IEC 62474:2018

Material declaration for products of and for the electrotechnical industry

IEC 62474:2018 specifies the procedure, content, and form relating to material declarations for products of companies operating in and supplying the electrotechnical industry. Process chemicals and emissions during product use are not in the scope of this International Standard. It provides data to downstream manufacturers that:
- allows them to assess products against substance restriction compliance requirements;
- they can use in their environmentally conscious design process and across all product life cycle phases. A database associated with this document is available at http://std.iec.ch/iec62474. It contains the list of:
- Declarable substance groups and declarable substances;
- Reference Substances;
- Material classes;
- XML schema for data format and exchange and the accompanying developer table.
IEC 62474:2018 cancels and replaces the first edition published in 2012. This edition constitutes a technical revision.
IEC 62474:2018 includes the following significant technical changes with respect to the previous edition:
a) The material classes and exemption lists capabilities have been improved.
b) The introduction and scope have new diagrams and information to give a better overview of the standard and identify what information is mandatory, optional or conditionally mandatory.
c) Definitions have been added. Minimum requirements to be in conformance with the IEC 62474 standard are defined, including XML format as the officially accepted format. By defining an authority, list identity and list version, the standard format could be used for lists other than the IEC 62474 database.
d) Terms have been aligned for consistency throughout the document. For example, the “IEC 62474 database” was previously referred to as “IEC 62474 database”, “IEC 62474”, “IEC 62474 Database”, “IEC 62474 DB”.
e) The annexes have been removed as they are now contained within documents managed by the validation team 62474 (VT 62474). Annex A (Annex B in the previous edition) is provided for non-XML users as a reference only.

Déclaration de matières pour des produits de et pour l'industrie électrotechnique

La CEI 62474:2018 décrit la procédure, le contenu et la forme des déclarations de matières pour les produits des entreprises et des fournisseurs de l'industrie électrotechnique. Les produits chimiques et les émissions du processus pendant l'utilisation du produit n'entrent pas dans le domaine d'application de la présente Norme internationale. Elle fournit aux fabricants situés en aval des données qui:
- leur permettent d'évaluer des produits au vu des exigences de conformité et de restriction de substances;
- peuvent être utilisées dans le cadre de leur processus d'écoconception et dans toutes les phases du cycle de vie du produit. Une base de données associée au présent document est disponible à l'adresse http://std.iec.ch/iec62474. Elle contient la liste des:
- groupes de substances déclarables et les substances déclarables;
- substances de référence;
- classes de matières;
- schémas XML pour le format et l'échange de données et le tableau développeurs d'accompagnement.
IEC 62474:2018 annule et remplace la première édition parue en 2012. Cette édition constitue une révision technique.
IEC 62474:2018 inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Les possibilités des classes de matières et listes d’exemptions ont été améliorées.
b) L’introduction et le domaine d’application comportent de nouveaux schémas et de nouvelles informations permettant de donner un meilleur aperçu de la norme et d’identifier les informations obligatoires, facultatives ou obligatoires sous conditions.
c) Des définitions ont été ajoutées. Des exigences minimales devant être conformes à la norme IEC 62474 sont définies. Elles comprennent le format XML, considéré comme le format officiellement reconnu. En définissant une autorité, un identifiant et une version de liste, le format de la norme peut être utilisé pour des listes autres que celles de la base de données de l’IEC 62474.
d) Le document a été amélioré dans un souci d’homogénéisation des termes utilisés. Par exemple, la “base de données de l’IEC 62474” était référencée de différentes manières telles que “base de données de l’IEC 62474”, “IEC 62474”, “Base de données de l’IEC 62474”, “BD IEC 62474”.
e) Les annexes ont été supprimées car elles sont contenues dans des documents gérés par l’équipe de validation 62474 (VT 62474). L’Annexe A (Annexe B de l'édition précédente) est destinée aux utilisateurs non XML, comme référence seulement.

Overview

IEC 62474:2018 - Material declaration for products of and for the electrotechnical industry defines the procedure, required content and format for material declarations used across the electrotechnical supply chain. The standard helps suppliers and downstream manufacturers exchange consistent material- and substance-related data needed to assess products against substance restriction compliance requirements and to support environmentally conscious design across product life‑cycle phases. Process chemicals and emissions during product use are explicitly out of scope. An associated, maintained database and the official XML schema are available at http://std.iec.ch/iec62474.

Key topics and requirements

• Declaration scope and structure: Specifies base (mandatory) and additional (optional or conditionally mandatory) data elements covering business information, product and product‑part details, materials, and substances.
• Declarable substances and material classes: Lists in the IEC 62474 database include declarable substance groups (DSGs), declarable substances (DSs), reference substances and defined material classes.
• Reporting thresholds and criteria: Defines criteria, thresholds and reportable applications for DSs/DSGs and thresholds for material classes to determine when reporting is required.
• Composition and compliance declarations: Data models and required fields for composition declarations and declarations intended to demonstrate compliance with restriction rules.
• Data format and exchange: The officially accepted exchange format is XML. The standard includes an XML schema and developer guidance to enable consistent data exchange (one‑way and two‑way).
• Database maintenance and governance: Procedures and roles (validation team VT 62474) for maintaining the IEC 62474 database, exemption lists and data format, including list identity/versioning and authority metadata so the format can be used beyond the IEC database.
• Edition changes (2018): Technical revision from the 2012 edition - improved material class/exemption capabilities, clearer mandatory/optional information diagrams, added definitions and conformance minimums, aligned terminology, and annex management moved under VT 62474.

Applications and users

IEC 62474:2018 is practical for:

• Manufacturers and suppliers in the electrotechnical sector preparing and exchanging material declarations.
• Downstream manufacturers who need reliable data to assess supplier parts against substance-restriction regimes.
• Ecodesign and product‑lifecycle teams integrating material/substance data into design decisions.
• Compliance, procurement and supply‑chain managers responsible for sourcing, reporting and regulatory readiness.

Related standards (context)

IEC 62474 provides interoperable material‑declaration infrastructure for industry compliance and EHS reporting. It is commonly used alongside regional and national substance‑restriction regulations and organizational EHS reporting programs.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

INTRODUCTION
The electrotechnical industry tracks and declares specific information about the material
composition of its products for compliance and environmentally conscious design
requirements. The electrotechnical industry needs to gather information about the composition
of products and product parts that are purchased from suppliers for incorporation into their
products. Currently material declarations are driven by individual product manufacturer’s
specifications and there is no internationally accepted standardization. This results in
economic inefficiencies. To simplify requirements across the supply chain and to improve
economic efficiencies, it is necessary to standardize the exchange of material composition
data and provide requirements for material declarations.
This International Standard benefits the electrotechnical industry by establishing requirements
for reporting of substances and materials, standardizing protocols, and facilitating transfer
and processing of data.
This document benefits the electrotechnical industry by establishing requirements for
reporting of material declaration data, standardizing protocols, and facilitating the transfer and
processing of data. Material declarations are used by the electrotechnical industry to track
and declare specific product information used for compliance and/or environmentally
conscious design (ECD) considerations. To simplify requirements across the supply chain and
to improve economic efficiencies, it is important to standardize the exchange of product,
product part, material and substance data, and provide requirements within material
declarations.
IEC 62474 is made of two parts: this document, which contains requirements for material
declarations and a database containing information such as a declarable substance list (DSL),
exemption list and data exchange format (see Clause 8).
This document defines the two most common types of material declarations and their
requirements:
1) Declaration for compliance – is always at a product level in reference to the list of
declarable substances and declarable substance groups within the IEC 62474 declarable
substance list (DSL).
2) Composition declaration – is the much more detailed product part level reporting down to
individual substances contained within the IEC 62474 DSL.
The IEC 62474 database is maintained by the validation team (VT 62474) which updates
information in the IEC 62474 database based on requirements specified in the IEC 62474
standard (see Clause 8).
By fulfilling the requirements of the IEC 62474 standard and based on the information from
the IEC 62474 database, two types of declaration can be created as shown in Figure 1 below.
• a declaration for compliance which is the information required to determine product
compliance with substance regulations and market needs (see 4.4);
• a composition declaration that is the information required to assess where declarable
substances above threshold are contained in the product (see 4.5).
The transmission of information in the supply chain can be done in two modes:
• Distribution mode: The supplier provides material declaration data about their product(s)
to a recipient.
• Requester/responder mode: The requester determines the type of material declaration(s)
the responder will provide.

Figure 1 – IEC 62474 principles
The IEC 62474 principles are determined in the following clauses:
• Clause 4 specifies requirements for material declarations.
• Clause 5 specifies the criteria and thresholds for declarable substances (DSs), declarable
substance groups (DSGs) and material classes in the IEC 62474 database.
• Clause 6 specifies the criteria for exemption lists in the IEC 62474 database.
• Clause 7 specifies the IEC 62474 database data format and exchange requirements with
further information in Annex A (informative).
• Clause 8 specifies the IEC 62474 database maintenance process.

MATERIAL DECLARATION FOR PRODUCTS OF
AND FOR THE ELECTROTECHNICAL INDUSTRY

1 Scope
This document specifies the procedure, content, and form relating to material declarations for
products and accessories of companies organizations operating in and supplying to the
electrotechnical industry. Process chemicals, emissions during product use and product
packaging material are not in the scope of this document.
The main intended use of this document is to provide data to downstream manufacturers up
and down the supply chain that:
• allows them organizations to assess products against substance restriction compliance
requirements,
• they can use allows organizations to use this information in their environmentally
conscious design process and across all product life cycle phases.
Clause 4 specifies requirements for a material declaration.
Clause 5 specifies the criteria for declarable substances and material classes in the
IEC 62474 database associated with this standard.
Clause 6 specifies the data format and exchange requirements to be included in the
IEC 62474 database.
Clause 7 specifies the process to regularly update and maintain the IEC 62474 database.
Although this International Standard specifies base requirements, it offers flexibility to product
manufacturers and suppliers in the selection of additional requirements or information.
This document specifies mandatory declaration requirements and also provides optional
declaration requirements.
This document does not provide suggest any specific method or process to capture material
composition data declaration data in the supply chain. However, it provides a data format
used to transfer information within the supply chain. Organizations have the flexibility to
determine the most appropriate method to capture material composition declaration data
without compromising data utility and quality. This document is intended to allow reporting
based on engineering judgement, supplier material declarations, and/or on sampling and
testing.

4 Requirements for material declarations
4.1 General
This clause describes the base requirements and additional requirements for a material
declaration. Subclause 4.2 describes the base data requirements and Subclause 4.3
describes additional requirements, should the manufacturer and supplier agree to declare
more.
Clause 4 is organized in the order of the conceptual diagrams (see Figures 1 and 2) for ease
of understanding. Required information is shown with solid boxes and arrows. Options are
shown within dotted boxes. Product, substance groups or substances with a mandatory
reporting requirement in the IEC 62474 database are mandatory objects in this approach.
Product parts, material classes, materials, and substance groups or substances without a
mandatory reporting requirement in the IEC 62474 database are optional objects in this
approach. Substance groups and substances not listed in the IEC 62474 database are also
optional objects. Further mandatory requirements apply without being displayed in the
diagrams (e.g. mass or mass percent).
See informative Annex A for examples related to requirements for material declaration.

MATERIAL DECLARATION FOR PRODUCTS OF
AND FOR THE ELECTROTECHNICAL INDUSTRY

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62474 has been prepared by IEC Technical Committee 111:
Environmental standardization for electrical and electronic products and systems.
This second edition cancels and replaces the first edition published in 2012. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The material classes and exemption lists capabilities have been improved.
b) The introduction and scope have new diagrams and information to give a better overview
of the standard and identify what information is mandatory, optional or conditionally
mandatory.
c) Definitions have been added. Minimum requirements to be in conformance with the
IEC 62474 standard are defined, including XML format as the officially accepted format.
By defining an authority, list identity and list version, the standard format could be used
for lists other than the IEC 62474 database.

d) Terms have been aligned for consistency throughout the document. For example, the
“IEC 62474 database” was previously referred to as “IEC 62474 database”, “IEC 62474”,
“IEC 62474 Database”, “IEC 62474 DB”.
e) The annexes have been removed as they are now contained within documents managed
by the validation team 62474 (VT 62474). Annex A (Annex B in the previous edition) is
provided for non-XML users as a reference only.
The text of this International Standard is based on the following documents:
FDIS Report on voting
111/498/FDIS 111/503/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62474 series, published under the general title Material
declaration for products of and for the electrotechnical industry, can be found on the IEC
website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This document benefits the electrotechnical industry by establishing requirements for
reporting of material declaration data, standardizing protocols, and facilitating the transfer and
processing of data. Material declarations are used by the electrotechnical industry to track
and declare specific product information used for compliance and/or environmentally
conscious design (ECD) considerations. To simplify requirements across the supply chain and
to improve economic efficiencies, it is important to standardize the exchange of product,
product part, material and substance data, and provide requirements within material
declarations.
IEC 62474 is made of two parts: this document, which contains requirements for material
declarations and a database containing information such as a declarable substance list (DSL),
exemption list and data exchange format (see Clause 8).
This document defines the two most common types of material declarations and their
requirements:
1) Declaration for compliance – is always at a product level in reference to the list of
declarable substances and declarable substance groups within the IEC 62474 declarable
substance list (DSL).
2) Composition declaration – is the much more detailed product part level reporting down to
individual substances contained within the IEC 62474 DSL.
The IEC 62474 database is maintained by the validation team (VT 62474) which updates
information in the IEC 62474 database based on requirements specified in the IEC 62474
standard (see Clause 8).
By fulfilling the requirements of the IEC 62474 standard and based on the information from
the IEC 62474 database, two types of declaration can be created as shown in Figure 1 below.
• a declaration for compliance which is the information required to determine product
compliance with substance regulations and market needs (see 4.4);
• a composition declaration that is the information required to assess where declarable
substances above threshold are contained in the product (see 4.5).
The transmission of information in the supply chain can be done in two modes:
• Distribution mode: The supplier provides material declaration data about their product(s)
to a recipient.
• Requester/responder mode: The requester determines the type of material declaration(s)
the responder will provide.
Figure 1 – IEC 62474 principles
The IEC 62474 principles are determined in the following clauses:
• Clause 4 specifies requirements for material declarations.
• Clause 5 specifies the criteria and thresholds for declarable substances (DSs), declarable
substance groups (DSGs) and material classes in the IEC 62474 database.
• Clause 6 specifies the criteria for exemption lists in the IEC 62474 database.
• Clause 7 specifies the IEC 62474 database data format and exchange requirements with
further information in Annex A (informative).
• Clause 8 specifies the IEC 62474 database maintenance process.

MATERIAL DECLARATION FOR PRODUCTS OF
AND FOR THE ELECTROTECHNICAL INDUSTRY

1 Scope
This document specifies the procedure, content, and form relating to material declarations for
products and accessories of organizations operating in and supplying to the electrotechnical
industry. Process chemicals, emissions during product use and product packaging material
are not in the scope of this document.
The main intended use of this document is to provide data up and down the supply chain that:
• allows organizations to assess products against substance compliance requirements,
• allows organizations to use this information in their environmentally conscious design
process and across all product life cycle phases.
This document specifies mandatory declaration requirements and also provides optional
declaration requirements.
This document does not suggest any specific method or process to capture material
declaration data in the supply chain. However, it provides a data format used to transfer
information within the supply chain. Organizations have the flexibility to determine the most
appropriate method to capture material declaration data without compromising data utility and
quality. This document is intended to allow reporting based on engineering judgement,
supplier material declarations, and/or sampling and testing.

4 Requirements for material declarations
4.1 General
4.1.1 Overview
Clause 4 describes the requirements for material declarations as specified in 4.1 through 4.7.
Figure 2 below shows the concept of material declaration capabilities. Some subclauses, such
as business information, are required while other subclauses, such as material classes, are
optional. The material declaration shall include a declaration for compliance (4.4) or a
composition declaration (4.5). It may also include both.

Figure 2 – Material declaration capabilities
• Material declaration: specifies the basic rules for a material declaration (4.1).
• Business information: specifies the business information, such as company name and
contact information (4.2).
• Product information: specifies the product and its attributes associated with the material
declaration (4.3).
• Declaration for compliance: specifies the information required to assess product
compliance (4.4).
• Composition declaration: specifies the information about substances, materials, and/or
product parts contained in the product (4.5).
• Material class declaration: specifies the information required for an optional material class
declaration (4.6).
• Query list: specifies a list of statements with true/false responses (4.7.1).
• Attachments: specifies the capability to include supporting documents within a material
declaration (4.7.2).
Figure 3 summarizes what elements are mandatory, optional, or conditional in a declaration
for compliance and a composition declaration.

– 14 – IEC 62474:2018 © IEC 2018

Figure 3 – Material declaration structure
The conceptual diagrams (see Figure 4 and Figure 5) are high level views of the declaration
for compliance (Figure 4) and composition declaration models (Figure 5). In both figures,
required information is shown with solid boxes and arrows. Optional information is shown
within dotted boxes.
Figure 4 – Data model for a declaration for compliance
A declaration for compliance provides data at the product level. Product, DSs and DSGs with
mandatory reporting requirements in the IEC 62474 DSL are mandatory objects in the
declaration for compliance (see 4.4 and Figure 4).

Figure 5 – Data model for a composition declaration
A composition declaration provides substance data at a material and/or product part and/or
product level. This data can also be used to verify compliance of a product.
For simplicity, not all of the mandatory requirements are displayed in the diagrams (e.g. mass
or mass percent information or mandatory declaration of certain product parts or materials in
the composition declaration when the reporting threshold level refers to such product parts or
materials and the reporting threshold level is exceeded) (see 4.5 for details).
The developer’s table within the IEC 62474 database contains a full description of mandatory
and optional requirements. Annex A provides an informative reference for mandatory and
optional information. However, if there is a discrepancy between the IEC 62474 database and
Annex A, the IEC 62474 database shall take precedence.
4.1.2 Conformity to the IEC 62474 standard
For a material declaration to conform to the IEC 62474 standard, it shall utilize the IEC 62474
database consisting of the DSL, material class list and the data exchange format and meet
the requirements specified in this document. The material declaration shall specify the
declarable substance list authority as “IEC62474” and the list identity and list version as
specified within the IEC 62474 database.
This document enables the declaration against other lists. If a list contains, at minimum, the
IEC 62474 DSL, utilizes the IEC 62474 data exchange format, and meets the requirements
specified in the standard, it is in conformity with the standard. If other lists are used, they
shall contain a list authority, list identity and list version and should be based on industry
standard requirements. If a list does not contain at minimum the IEC 62474 DSL, it is not in
conformity with this document.

– 16 – IEC 62474:2018 © IEC 2018
4.1.3 General requirements
a) In the case where the requester requests more than the mandatory requirements of a
material declaration as specified in this document and the IEC 62474 database, the
contracting parties should agree to details, such as safeguards protecting supplier trade
secrets at the request of the supplier.
b) The International System of Units (SI) shall be used.
4.2 Business information
Business information shall include company information, contact information and date, as well
as other data specified in the data exchange format in the IEC 62474 database. The transfer
of material declaration information uses either the distribution mode, where only the
responder’s business information shall be provided or the requester/responder mode, where
both the requester’s and the responder’s business information shall be provided.
4.3 Product information
The following requirements shall apply to products:
a) A declaration for compliance or a composition declaration shall be provided for a product
or product family.
NOTE 1 Only the supplier is likely to know the appropriate product family groupings for material declaration
purposes based on their technical knowledge of product material content.
b) The product shall have an identification and a mass assigned. In the case of a product
family, the identification and mass of each product within the product family shall be
specified.
NOTE 2 When each product in the product family has the same mass, it is sufficient to provide this mass just
once.
c) If a product contains a DS or DSG substance(s) that:
– has a reporting threshold level based on ‘article’,
– is present at or above the reporting threshold level for a reportable application, and
– is within the declaration of the product,
then the product shall be identified as an article.
4.4 Declaration for compliance requirements
4.4.1 General information
A declaration for compliance provides information about the presence or absence of DSs and
DSGs as listed in the DSL for a product. Each DS and DSG entry within the DSL requires a
positive (“true”) or negative (“false”) response. This information allows the requester to assess
their product compliance with substance regulations and market needs at a product level.
4.4.2 DSs and DSGs with mandatory reporting requirements
DSs or DSGs with a mandatory reporting requirement in the IEC 62474 DSL shall be reported.
When reporting DSs or DSGs with a mandatory reporting requirement, the following
requirements apply:
a) The DSs and DSGs listed in the IEC 62474 DSL shall be assigned to the product.
b) Each such DS and DSG shall be named as given in the IEC 62474 DSL and shall include
the reportable application and the reporting threshold level. The DSL entry identity
associated with the DS or DSG entry in the DSL should be declared. Other identity(s)
such as the CAS Registry Number may also be declared.
c) A declaration on the presence of DSs and DSGs at or above the reporting threshold level
for an applicable reportable application provided in the IEC 62474 DSL shall have a
positive (“true”) response for all such DSs or DSGs.

d) A declaration on the absence of DSs and DSGs shall have a negative (“false”) response
for DSs or DSGs provided in the IEC 62474 DSL that are:
– not present, or
– present below the reporting threshold level for an applicable reportable application, or
– present and the reportable application is not applicable.
e) The presence of DSs or DSGs shall be quantified if they are present in the product at or
above the reporting threshold level for an applicable reportable application given in the
IEC 62474 DSL.
– The mass percent of each DS or DSG within the product shall be provided.
– The mass percent shall be calculated based on the reporting threshold relative to the
reporting threshold level (e.g. product part or material) as specified in mass
information requirements in the IEC 62474 DSL.
• If such DSs or DSGs have reporting threshold levels specified in the IEC 62474
DSL referring to the product part, the declaration of the DS or DSG shall include
the mass percent of the product part.
• If DSs or DSGs have reporting threshold levels specified in the IEC 62474 DSL that
refer to the material, the declaration of the DS or DSG shall include the material
mass percent. The material mass percent is the percentage of the DS or DSG in
the material.
• If the mass percent of a DS and/or DSG can occur within a range of values, then
the maximum (worst case) value shall be declared.
NOTE 1 If the mass percent of a declarable substance can range from 1,1 % to 1,2 %, then a value
of 1,2 % is declared.
NOTE 2 The IEC 62474 DSL lists some DSs and DSGs that require reporting as percentage of the
material mass.
NOTE 3 The reporting requirement as percentage of the material mass can differ, e.g. the numerator
for this percentage can be the sum of the masses of all DSs belonging to this DSG present or just the
mass of a specific element. Details are given in the IEC 62474 DSL.
– If the DSs or DSGs have a mass reporting requirement specified in the mass
information requirements field of the IEC 62474 DSL, then the mass of the DSs or
DSGs shall be declared.
NOTE 4 The declaration of mass is in addition to the requirements specified to declare mass percent.
NOTE 5 The mass of DSs and/or DSGs in the product is sometimes necessary to meet regulatory
requirements and can be used to assess recyclability of a product.
– If the responder (supplier) is uncertain on the applicability of the reportable application
to the product, then the DSs or DSGs shall be declared if they are present at or above
the reporting threshold level in the supplied product.
– If the declaration of a DS or DSG includes a mass percent, identification of the
material, product part or product that represents the denominator of such mass percent
may be provided and included in the material declaration that is passed through the
supply chain.
f) In general, if there is more than one occurrence of a DS or DSG within a reportable
application that is present at or above the reporting threshold within the product, the
occurrence with the highes

MATERIAL DECLARATION FOR PRODUCTS OF
AND FOR THE ELECTROTECHNICAL INDUSTRY

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
This consolidated version of the official IEC Standard and its amendment has been
prepared for user convenience.
IEC 62474 edition 2.1 contains the second edition (2018-11) [documents 111/498/FDIS
and 111/503/RVD] and its amendment 1 (2020-12) [documents 111/511/CDV and
111/561/RVC].
In this Redline version, a vertical line in the margin shows where the technical content
is modified by amendment 1. Additions are in green text, deletions are in strikethrough
red text. A separate Final version with all changes accepted is available in this
publication.
© IEC 2020
International Standard IEC 62474 has been prepared by IEC Technical Committee 111:
Environmental standardization for electrical and electronic products and systems.
This second edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) The material classes and exemption lists capabilities have been improved.
b) The introduction and scope have new diagrams and information to give a better overview
of the standard and identify what information is mandatory, optional or conditionally
mandatory.
c) Definitions have been added. Minimum requirements to be in conformance with the
IEC 62474 standard are defined, including XML format as the officially accepted format.
By defining an authority, list identity and list version, the standard format could be used
for lists other than the IEC 62474 database.
d) Terms have been aligned for consistency throughout the document. For example, the
“IEC 62474 database” was previously referred to as “IEC 62474 database”, “IEC 62474”,
“IEC 62474 Database”, “IEC 62474 DB”.
e) The annexes have been removed as they are now contained within documents managed
by the validation team 62474 (VT 62474). Annex A (Annex B in the previous edition) is
provided for non-XML users as a reference only.
f) Two types of material declarations, declaration for compliance and composition
declaration, and their requirements are defined.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62474 series, published under the general title Material
declaration for products of and for the electrotechnical industry, can be found on the IEC
website.
The committee has decided that the contents of the base publication and its amendment will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION
This document benefits the electrotechnical industry by establishing requirements for
reporting of material declaration data, standardizing protocols, and facilitating the transfer and
processing of data. Material declarations are used by the electrotechnical industry to track
and declare specific product information used for compliance and/or environmentally
conscious design (ECD) considerations. To simplify requirements across the supply chain and
to improve economic efficiencies, it is important to standardize the exchange of product,
product part, material and substance data, and provide requirements within material
declarations.
IEC 62474 is made of two parts: this document, which contains requirements for material
declarations and a database containing information such as a declarable substance list (DSL),
exemption list and data exchange format (see Clause 8).
This document defines the two most common types of material declarations and their
requirements:
1) Declaration for compliance – is always at a product level in reference to the list of
declarable substances and declarable substance groups within the IEC 62474 declarable
substance list (DSL).
2) Composition declaration – is the much more detailed product part level reporting down to
individual substances contained within the IEC 62474 DSL.
The standard contains the IEC 62474 data exchange format and IEC 62474 lists, including the
declarable substance list (DSL), material class list (MCL) and exemption list. IEC 62474
allows other lists to be used with the IEC 62474 data exchange format.
The IEC 62474 database is maintained by the validation team (VT 62474) which updates
information in the IEC 62474 database based on requirements specified in the IEC 62474
standard (see Clause 8).
By fulfilling the requirements of the IEC 62474 standard and based on the information from
the IEC 62474 database, two types of declaration can be created as shown in Figure 1 below.
• a declaration for compliance which is the information required to determine product
compliance with substance regulations and market needs (see 4.4);
• a composition declaration that is the information required to assess where declarable
substances above threshold are contained in the product (see 4.5).
The transmission of information in the supply chain can be done in two modes:
• Distribution mode: The supplier provides material declaration data about their product(s)
to a recipient.
• Requester/responder mode: The requester determines the type of material declaration(s)
the responder will provide.

1 Scope
This document specifies the procedure, content, and form relating to material declarations for
products and accessories of organizations operating in and supplying to the electrotechnical
industry. Process chemicals, emissions during product use and product packaging material
are not in the scope of this document.
The main intended use of this document is to provide data up and down the supply chain that:
• allows organizations to assess products against substance compliance requirements,
• allows organizations to use this information in their environmentally conscious design
process and across all product life cycle phases.
This document specifies mandatory declaration requirements and also provides optional
declaration requirements.
This document does not suggest any specific method or process to capture material
declaration data in the supply chain. However, it provides a data format used to transfer
information within the supply chain. Organizations have the flexibility to can determine the
most appropriate method to capture material declaration data without compromising data
utility and quality. This document is intended to allow reporting based on engineering
judgement, supplier material declarations, and/or sampling and testing.

4 Requirements for material declarations
4.1 General
4.1.1 Overview
Clause 4 describes the requirements for material declarations as specified in 4.1 through 4.7.
Figure 2 below shows the concept of material declaration capabilities. Some subclauses, such
as business information, are required while other subclauses, such as material classes, are
optional. The material declaration shall include a declaration for compliance (4.4) or a
composition declaration (4.5). It may also include both.

© IEC 2020
Figure 2 – Material declaration capabilities
• Material declaration: specifies the basic rules for a material declaration (4.1).
• Business information: specifies the business information, such as company name and
contact information (4.2).
• Product information: specifies the product and its attributes associated with the material
declaration (4.3).
• Declaration for compliance: specifies the information required to assess product
compliance (4.4).
• Composition declaration: specifies the information about substances, materials, and/or
product parts contained in the product (4.5).
• Material class declaration: specifies the information required for an optional material class
declaration (4.6).
• Query list: specifies a list of statements with true/false responses (4.7.1).
• Attachments: specifies the capability to include supporting documents within a material
declaration (4.7.2).
Figure 3 summarizes what elements are mandatory, optional, or conditional in a declaration
for compliance and a composition declaration.

Figure 3 – Material declaration structure
The conceptual diagrams (see Figure 4 and Figure 5) are high level views of the declaration
for compliance (Figure 4) and composition declaration models (Figure 5). In both figures,
required information is shown with solid boxes and arrows. Optional information is shown
within dotted boxes.
Figure 4 – Data model for a declaration for compliance
A declaration for compliance provides data at the product level. Product, DSs and DSGs with
mandatory reporting requirements in the IEC 62474 DSL are mandatory objects in the
declaration for compliance (see 4.4 and Figure 4).

© IEC 2020
Figure 5 – Data model for a composition declaration
A composition declaration provides substance data at a material and/or product part and/or
product level. This data can also be used to verify compliance of a product.
For simplicity, not all of the mandatory requirements are displayed in the diagrams (e.g. mass
or mass percent information or mandatory declaration of certain product parts or materials in
the composition declaration when the reporting threshold level refers to such product parts or
materials and the reporting threshold level is exceeded) (see 4.5 for details).
The developer’s table within the IEC 62474 database contains a full description of mandatory
and optional requirements. Annex A provides an informative reference for mandatory and
optional information. However, if there is a discrepancy between the IEC 62474 database and
Annex A, the IEC 62474 database shall take precedence.
4.1.2 Conformity to the IEC 62474 standard
For a material declaration to conform to the IEC 62474 standard, it shall utilize the IEC 62474
database consisting of the DSL, material class list and the data exchange format and meet
the requirements specified in this document. The material declaration shall specify the
declarable substance list authority as “IEC62474” and the list identity and list version as
specified within the IEC 62474 database.
Acceptable statements of IEC 62474 conformance are also:
• conformance to the "IEC 62474 data exchange format";
• conformance to the "IEC 62474 DSL".

– 16 – IEC 62474:2018+AMD1:2020 CSV
© IEC 2020
This document enables the declaration against other lists. If a list contains, at minimum, the
IEC 62474 DSL, utilizes the IEC 62474 data exchange format, and meets the requirements
specified in the standard this document, it is in conformity with the standard this document. If

other lists are used, they shall contain a list authority, list identity and list version and should
be based on industry standard requirements. If a list does not contain at minimum the
IEC 62474 DSL, it is not in conformity with this document.
However, if the material declaration meets the requirements of the IEC 62474 data exchange
format, but utilizes an alternate DSL, the material declaration can be claimed to conform to
the "IEC 62474 data exchange format".
4.1.3 General requirements
a) In the case where the requester requests more than the mandatory requirements of a
material declaration as specified in this document and the IEC 62474 database, the
contracting parties should agree to details, such as safeguards protecting supplier trade
secrets at the request of the supplier.
b) The International System of Units (SI) shall be used.
4.2 Business information
Business information shall include company information, contact information and date, as well
as other data specified in the data exchange format in the IEC 62474 database. The transfer
of material declaration information uses either the distribution mode, where only the
responder’s business information shall be provided or the requester/responder mode, where
both the requester’s and the responder’s business information shall be provided.
4.3 Product information
The following requirements shall apply to products:
a) A declaration for compliance or a composition declaration shall be provided for a product
or product family.
NOTE 1 Only the supplier is likely to know the appropriate product family groupings for material declaration
purposes based on their technical knowledge of product material content.
b) The product shall have an identification and a mass assigned. In the case of a product
family, the identification and mass of each product within the product family shall be
specified.
NOTE 2 When each product in the product family has the same mass, it is sufficient to provide this mass just
once.
c) If a product contains a DS or DSG substance(s) that:
– has a reporting threshold level based on ‘article’,
– is present at or above the reporting threshold level for a reportable application, and
– is within the declaration of the product,
then the product shall be identified as an article.
4.4 Declaration for compliance requirements
4.4.1 General information
A declaration for compliance provides information about the presence or absence of DSs and
DSGs as listed in the DSL for a product. Each DS and DSG entry within the DSL requires a
positive (“true”) or negative (“false”) response. This information allows the requester to assess
their product compliance with substance regulations and market needs at a product level.

© IEC 2020
4.4.2 DSs and DSGs with mandatory reporting requirements
DSs or DSGs with a mandatory reporting requirement in the IEC 62474 DSL shall be reported.
When reporting DSs or DSGs with a mandatory reporting requirement, the following
requirements apply:
a) The DSs and DSGs listed in the IEC 62474 DSL shall be assigned to the product.
b) Each such DS and DSG shall be named as given in the IEC 62474 DSL and shall include
the reportable application and the reporting threshold level. The DSL entry identity
associated with the DS or DSG entry in the DSL should be declared. Other identity(s)
such as the CAS Registry Number may also be declared.
c) A declaration on the presence of DSs and DSGs at or above the reporting threshold level
for an applicable reportable application provided in the IEC 62474 DSL shall have a
positive (“true”) response for all such DSs or DSGs.
d) A declaration on the absence of DSs and DSGs shall have a negative (“false”) response
for DSs or DSGs provided in the IEC 62474 DSL that are:
– not present, or
– present below the reporting threshold level for an applicable reportable application, or
– present and the reportable application is not applicable.
e) The presence of DSs or DSGs shall be quantified if they are present in the product at or
above the reporting threshold level for an applicable reportable application given in the

IEC 62474 DSL.
– The mass percent of each DS or DSG within the product shall be provided.
– The mass percent shall be calculated based on the reporting threshold relative to the
reporting threshold level (e.g. product part or material) as specified in mass
information requirements in the IEC 62474 DSL.
• If such DSs or DSGs have reporting threshold levels specified in the IEC 62474
DSL referring to the product part, the declaration of the DS or DSG shall include
the mass percent of the product part.
• If DSs or DSGs have reporting threshold levels specified in the IEC 62474 DSL that
refer to the material, the declaration of the DS or DSG shall include the material
mass percent. The material mass percent is the percentage of the DS or DSG in
the material.
• If the mass percent of a DS and/or DSG can occur within a range of values, then
the maximum (worst case) value shall be declared.
NOTE 1 If the mass percent of a declarable substance can range from 1,1 % to 1,2 %, then a value
of 1,2 % is declared.
NOTE 2 The IEC 62474 DSL lists can list some DSs and DSGs that require reporting as percentage
of the material mass.
NOTE 3 The reporting requirement as percentage of the material mass can differ, e.g. the numerator
for this percenta
