GENERIC SPECIFICATION OF INFORMATION ON PRODUCTS –
Part 1: Principles and methods
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.

INTRODUCTION
This PAS is intended as the first part of a standard series defining methods and guidelines for
the establishing of generic electronic specifications of information for products (including
plants, systems, equipment or components, in the following all called products), along its life
cycle for later use e.g. in the procurement, operating and maintenance.
This series is prepared to transfer the former paper-based applications of blank detail
specifications or product descriptions towards supporting the electronic business allowing the
evaluation and management of described items by computers.
This PAS establishes general principles required for the other parts of this series. It specifies
the infrastructure required to manage the product-related information as described in the
following parts along the life cycle.
Part 2 provides a generally applicable structure of a generic specification of information on
products presenting those common clauses which are independent of any specific equipment,
component and device. It serves as a guide for the preparation of technical specifications for
various items. Due to its generic type, particular issues referring to specific product classes
are excluded. These need to be obtained from the specific product descriptions within product
standards.
Part 2 is the basis for an XML based electronic template, serving as generic template for the
development of product-specific specifications of information by product committees within
IEC and ISO, industrial consortia or other industrial organizations.
The result of such product-specific blank detail specifications may be made available as a
web-based collection of product-specific specifications for information, allowing users and
technical committees to upload and/or download detail specifications for industrial use in the
business process.
A prerequisite of the above series is the existence of an international available data
dictionary, providing collections of data element types following common methods as defined
in the IEC 61360 series.
Referring from product descriptions to previously defined semantic data element type
descriptions is the key issue of an effective and secure electronic business. For the relations
among data element types, the associated data dictionary and the different specifications see
Figure 1.

Figure 2 shows a business scenario about the usage of a detail specification (based on the
generic specification) for information on products between business partners.
Figure 2 − Business scenario between partners
If a specification for information in the form of an electronic template is associated with a
schema for data exchange, e.g. an XML schema or any other tagged electronic file format, the
content of the product-specific detail specification can be easily used for import and export of
data values in conjunction with data bases for material management systems. See Figure 3.
A specification template can also be imported for the setting up of the internal structures
within a data base without having the need to import associated values.
Vice versa detail specifications can be generated to export data using a predefined template
based on the generic specification for information on products.

GENERIC SPECIFICATION OF INFORMATION ON PRODUCTS –
Part 1: Principles and methods
1 Scope
The IEC 62569 series of publications will provide principles and methods for the specification
of products by properties, e.g. in data sheets. It uses data element types defined in the data
dictionary of IEC 61360.
This PAS provides qualifiers to be used in addition to the properties considering life cycle and
other aspects. It is a prerequisite for the other parts of this series.

3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
NOTE Definitions taken from other standards (issued or in preparation) are not necessarily literally cited, but the
form is adapted.
3.1.1
product
result of labour or of a natural or industrial process
[IEC 61360-1, 2.11]
3.1.2

property
defined parameter suitable for the description and differentiation of objects
[ISO/IEC Guide 77-2, modified]
NOTE The term property used in this standard is not identical with the term data element type used in IEC 61360.
A data element type is a unit of data for which the identification, description and value representation have been
specified in the context of a dictionary, while the term property is used for an occurrence of such a data element
type in the context of a specification of an object. This distinction makes it possible to qualify a property in an
object specification and still refer to the same data element type definition in the dictionary.
3.1.7
specification
document that states requirements, functionally related characteristics, processes, or rules
related to a unique quality that an in-process part, a finished part, or a product shall possess
[IEC 62079, modified]

generic specification of information on products
product class independent specification of the properties of a product by the use of data
element types
3.1.9
product-class-specific specification (of information)
generic specification of information on products adapted to a specific product class
NOTE A product-class-specific specification is often used as a basis for the development of templates for use in
engineering activities. Depending on the tools in use different templates can be developed for the same purpose.
3.1.10
product-type-specific specification (of information)
product-class-specific specification of information adapted to a specific product type

4 Specifications
Product class or product type specific specifications, often also known as functional
specifications, device profiles or blank detail specifications, are used widely in industry. Such
specifications apply predefined properties of products. The properties are independent of any
specific product specimen at the time of preparing the specification.
During the life cycle of a product, each property will be associated with specific values which
are either specific to the referred product type or product specimen. The values of a property
may be selected from a range of predefined values.
Normally, such specifications are for the first time in the life cycle of a product (type) used in
the context of a (functional) specification.
This PAS takes provisions in order to reuse the once defined properties of a referred product
for different purposes at different points in time, e.g. starting with the inquiry, offer, contract,
delivery, operation, maintenance, etc.
In the past product class specific specifications have been used mostly on paper or in
electronic form intended for human reading only.
It is realized that such specifications need also be made available as computer interpretable
templates downloadable from a web server or other future web-based applications.
An electronic template is structured, grouping information in the form of sets of properties
required for specification, procurement, engineering planning and construction, operation and
maintenance along the life cycle of the referred product.
It is recommended to apply a generic structure for all specifications for products independent
of their types in order to ease and accelerate the use of a template also by humans.
Due to occurring changes of the value(s) associated with the same property of the same
product type in the development process, it is necessary to keep track of those changes, done
at the different stages in the life cycle. Therefore each change in such a specification and/or
property need be stored and clearly distinguished. This allows to keep track of changes of
values between different stages in the development process and to refer back to the originally
required values.
This PAS provides generic methods with respect to content–related issues contained in
product class specific specification.
It is of high industrial value to make the resulting electronic templates available for download
by market actors.
---------------------- Page: 13 ----------------------
– 12 – PAS 62569-1 © IEC:2009(E)
This standard series establishes general requirements with respect to:
– the structural content of a specification independent of a specific product class;
– the specification of properties describing a specific product class;
– the reuse of existing specifications and existing properties along the life cycle of a
described product;
– the general requirements with respect to a computer sensible evaluation of the data
contained in such an electronic template independent of their visual presentation in a
specification document;
– import and export requirements from and to data bases for the generation of electronic
detail specifications.
