29、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 sta
30、ndardization 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 prepara
31、tion 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 wi
32、th 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 sub
33、jects 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 technica
34、l 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
35、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 con
36、formity 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 dir
37、ectors, 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 arisi
38、ng 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 d
39、rawn 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 standar
40、dization 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 introduc
41、es 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. 62321-3-2 IEC
42、:2013 5 The text of this standard is based on the following documents: FDIS Report on voting 111/300/FDIS 111/310/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance wi
43、th the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62321 series can be found on the IEC website under the general title: Determination of certain substances in electrotechnical products. The committee has decided that the contents of this publication will remain unchanged until the st
44、ability 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. 6 62321-3-2 IEC:2013 INTRODUCTION The widespread use of electrotechnical
45、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
46、 polybrominated diphenyl ethers (PBDEs) 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 substan
47、ces 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 responsibil
48、ity of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions 62321-3-2 IEC:2013 7 DETERMINATION OF CERTAIN SUBSTANCES IN ELECTROTECHNICAL PRODUCTS Part 3-2: Screening Total bromine in polymers and electronics by Combustion Ion
49、Chromatography 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)
