Test method development - Guidelines for substance selection

IEC TR 62936:2016(E) provides guidelines for the selection of substances for the development of test method standards. The substances and substance groups listed in the IEC 62474 database are the primary source of candidate substances. Other substances that are under regulatory roadmap and market requirements can also be considered for this filtering and selection process.

TEST METHOD DEVELOPMENT –
GUIDELINES FOR SUBSTANCE SELECTION

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a Technical Report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 62936, which is a Technical Report, has been prepared by IEC technical
committee 111: Environmental standardization for electrical and electronic products and
systems.
The text of this Technical Report is based on the following documents:

111/410A/DTR 111/441/RVC
Full information on the voting for the approval of this Technical Report can be found in the
report on voting indicated in the above table.

INTRODUCTION
The large number of chemical substances currently regulated or under consideration for
regulation necessitates the need for the development of reliable and acceptable test methods
to be used as one approach for conformity assessment. For conformance demonstration, it is
vital that interested parties agree that a particular test method is technically correct (i.e.
provide reliable analytical results), is appropriate for the samples to be analysed, tested and
vetted by technical experts, and is unbiased in its application. These criteria are generally
fulfilled by test methods that are developed and published by a standards development
organization (SDO) (e.g. IEC, ISO). Because of limited resources and the length of time
needed to develop and validate these procedures, only a limited number of substances can be
addressed at any given time for test method development.
This document provides a process for logically filtering, prioritizing and selecting candidate
substances for development of test method standards. The objective of the filtering process is
to partition the list of candidate substances into groups based on relative importance. Given
that this document is intended for electrotechnical products, the candidate substances are
largely drawn, but not exclusively, from the substance lists recorded in the IEC 62474
database [1] on material declaration. The substances listed in the database are grouped into
3 categories with brief descriptions given below:
• IEC Criteria 1 – “currently regulated” or “explicitly included within an existing national law
or regulation in an IEC member country”. The law or regulation is applicable to
electrotechnical products and goes into force at a specific date.
• IEC Criteria 2 – “for assessment” or substance or substance group that meets criteria 1
with the exception that the law or regulation does not cite a specific effective date for the
requirements.
• IEC Criteria 3 – “for information only” or does not meet requirement for either criteria 1 or
2. However, “there is a recognized industry-wide common market requirement for reporting
this substance or substance group in electrotechnical products”.
NOTE Criterion/criteria is used in this document to denote a rule/principle for evaluating a substance against a
set of requirements. The use of the term IEC criteria is specific to the regulatory status of a particular substance as
defined in the IEC 62474 standard.
In addition to those substances that are under regulatory scrutiny, market requirements may
also be of major consideration for the development of IEC test method standards. There are
several very important influences that may dictate the ability of a product to enter or be
introduced into the marketplace. Examples of market driven requirements may include ®
EPEAT (Electronic Product Environment Assessment Tool), Low Halogen initiative set by the ®
electronics industry, Energy Star for energy efficient products and others. Although there
are no legal obligations that electrotechnical equipment meet the requirements set forth in
these initiatives, failure to do so may put the supplier at a severe competitive disadvantage. In
many cases, the supplier’s product may be disqualified for purchasing consideration for failu
