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.
IEC 62321-3-3 has been prepared by IEC technical committee 111: Environmental
standardization for electrical and electronic products and systems. It is an International
Standard.

INTRODUCTION
The widespread use of electrotechnical products has drawn increased attention to their impact
on the environment. In many countries all over the world, this has resulted in the adaptation of
regulations affecting wastes, substances and energy use of electrotechnical products.
The use of polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs) and
certain phthalates in electrotechnical products is of concern in many regions of the world.
The purpose of this document is therefore to provide a test method that will allow the
electrotechnical industry to determine the levels of polybrominated biphenyls (PBBs),
polybrominated diphenyl ethers (PBDEs), di-isobutyl phthalate (DIBP), di-n-butyl phthalate
(DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate
(DNOP), di-isononyl phthalate (DINP) and di-isodecyl phthalate (DIDP) in electrotechnical
products on a consistent global basis.
WARNING – Persons using this document should be familiar with normal laboratory
practice. This document does not purport to address all of the safety problems, if any,
associated with its use. It is the responsibility of the user to establish appropriate safety
and health practices and to ensure compliance with any national regulatory conditions.

Part 3-3: Screening – Polybrominated biphenyls,
polybrominated diphenyl ethers and phthalates in polymers
by gas chromatography-mass spectrometry using a
pyrolyser/thermal desorption accessory (Py/TD‑GC‑MS)



1 Scope
This part of IEC 62321 specifies the screening analysis of polybrominated biphenyls (PBBs),
polybrominated diphenyl ethers (PBDEs), di-isobutyl phthalate (DIBP), di-n-butyl phthalate
(DBP), benzylbutyl phthalate (BBP), di-(2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate
(DNOP), di-isononyl phthalate (DINP), and di-isodecyl phthalate (DIDP) in polymers of
electrotechnical products using the analytical technique of gas chromatography-mass
spectrometry using a pyrolyser/thermal desorption accessory (Py/TD-GC-MS).
This test method has been evaluated through the analysis of PP (polypropylene), PS
(polystyrene), and PVC (polyvinyl chloride) materials containing deca-BDE between 100 mg/kg
and 1 000 mg/kg and individual phthalates between 100 mg/kg to 4 000 mg/kg as depicted in
Annex J. Use of the methods described in this document for other polymer types, PBBs
(mono-deca), PBDEs (mono-deca) and phthalates or concentration ranges other than those
specified above has not been specifically evaluated.
