Determination of certain substances in electrotechnical products - Part 3-2: Screening test methods - Screening of total bromine in polymers and electronics by combustion - Ion chromatography (C-IC)

EN-IEC 62321-3-2 specifies the screening analysis of the total bromine (Br) in homogeneous materials found in polymers and electronics by using the analytical technique of combustion ion chromatography (C-IC). This test method has been evaluated for ABS (acrylonitrile butadiene styrene), EMC (epoxy molding compound), and PE (polyethylene) within the concentration ranges as specified in Table 1. The use of this method for other types of materials or concentration ranges outside those specified below has not been evaluated.

Standard EN-IEC 62321-3-2 določa presejalne analize skupnega broma (Br) v homogenih materialih, ki jih najdemo v polimerih in elektroniki, s pomočjo analitične tehnike zgorevalne ionske kromatografije (C-IC). Ta preskusna metoda je bila ocenjena za ABS (akrilonitril-butadien-stiren), EMC (epoksi zmesi za oblikovanje) in PE (polietilen) v koncentracijah, določenih v tabeli 1. Uporaba te metode za druge vrste materialov ali razpon koncentracij zunaj tistih, navedenih spodaj, ni bila ocenjena.

DETERMINATION OF CERTAIN SUBSTANCES

Part 3-2: Screening – Total bromine in polymers and electronics
by Combustion – Ion Chromatography

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 62321-3-2 has been prepared by IEC technical committee 111:
Environmental standardization for electrical and electronic products and systems.
The first edition of IEC 62321:2008 was a 'stand alone' standard that included an introduction,
an overview of test methods, a mechanical sample preparation as well as various test method
clauses.
This first edition of IEC 62321-3-2 introduces a new clause in the IEC 62321 series.
Future parts in the IEC 62321 series will gradually replace the corresponding clauses in
IEC 62321:2008. Until such time as all parts are published, however, IEC 62321:2008 remains
valid for those clauses not yet re-published as a separate part.

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 certain substances (e.g. lead (Pb), cadmium (Cd) and polybrominated diphenyl
ethers (PBDE’s)) in electrotechnical products, is a source of concern in current and proposed
regional legislation.
The purpose of the IEC 62321 series is therefore to provide test methods that will allow the
electrotechnical industry to determine the levels of certain substances of concern in
electrotechnical products on a consistent global basis.
WARNING – Persons using this International Standard should be familiar with normal
laboratory practice. This standard 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

1 Scope
Part 3-2 of IEC 62321 specifies the screening analysis of the total bromine (Br) in
homogeneous materials found in polymers and electronics by using the analytical technique
of combustion ion chromatography (C-IC).
This test method has been evaluated for ABS (acrylonitrile butadiene styrene), EMC (epoxy
molding compound), and PE (polyethylene) within the concentration ranges as specified in
Table 1.
The use of this method for other types of materials or concentration ranges outside those
specified below has not been evaluated.

4 Principle
4.1 Overview
The concept of 'screening' has been developed to reduce the amount of testing. Executed as
a predecessor to any other test analysis, the main objective of screening is to quickly
determine whether the screened part or section of a product:
– contains a certain substance at a concentration significantly higher than its value or values
chosen as criterion, and therefore may be deemed unacceptable;
– contains a certain substance at a concentration significantly lower than its value or values
chosen as criterion, and therefore may be deemed acceptable;
contains a certain substance at a concentration so close to the value or values chosen as
criterion that when all possible errors of measurement and safety factors are considered, no
conclusive decision can be made about the acceptable absence or presence of a certain

substance and, therefore, a follow-up action may be required, including further analysis using
verification testing procedures.
This test method is designed specifically to screen for bromine (Br) in polymers and
electronics in electrotechnical products. C-IC provides information on the total quantity of
bromine present in the sample, but does not identify compounds or valence states of the
bromine. Therefore, special attention shall be paid when screening for bromine, where the
result will reflect only the total bromine present. The presence of brominated flame retardants
PBB or PBDE shall be confirmed by a verification test procedure. When applying this method
to electronics “as received”, which, by the nature of their design, are not uniform, care shall
be taken in interpreting the results.
4.2 Principle of test
A sample of known weight or volume is placed into a sample boat and introduced at a
controlled rate into a high-temperature combustion tube. There the sample is combusted in an
oxygen-rich pyrohydrolyti
