290 (GC-MS), gas chromatography-mass spectrometry using

293 FOREWORD
294 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
295 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
296 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
297 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
298 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
299 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
300 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
301 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
302 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
303 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
304 consensus of opinion on the relevant subjects since each technical committee has representation from all
305 interested IEC National Committees.
306 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
307 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
308 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
309 misinterpretation by any end user.
310 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
311 transparently to the maximum extent possible in their national and regional publications. Any divergence between
312 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
313 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
314 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
315 services carried out by independent certification bodies.
316 6) All users should ensure that they have the latest edition of this publication.
317 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
318 members of its technical committees and IEC National Committees for any personal injury, property damage or
319 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
320 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
321 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
322 indispensable for the correct application of this publication.
323 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
324 rights. IEC shall not be held responsible for identifying any or all such patent rights.
325 International Standard IEC 62321-8 has been prepared by IEC technical committee 111:
326 Environmental standardization for electrical and electronic products and systems.
327 It has the status of a horizontal standard in accordance with IEC Guide 108.
328 This second edition cancels the first edition published in 2017 and replaces it with a technically
329 revised version.
330 In this second edition, the main technical changes with respect to the previous edition are as
331 follows :
332 a) the test methods have been evaluated by the test of PVC, PE, paint, rubber, and adhesive
333 in polymers of electrotechnical products.
334 b) determination of target phthalates in this second edition is expanded to 19 specific phthalates.

335 c) the GC-MS using a pyrolyser/thermal desorption (TD) accessory is used as quantitative
336 determination analysis of specific phthalates as well as screening analysis and semi-
337 quantitative analysis.
339 The text of this second edition is based on that of the first edition and the following documents:

354 INTRODUCTION
355 The widespread use of electrotechnical products has drawn increased attention to their impact
356 on the environment. In many countries all over the world this has resulted in the adaptation of
357 regulations affecting wastes, substances and energy use of electrotechnical products.
358 The use of certain substances (e.g. lead (Pb), cadmium (Cd), polybrominated diphenyl ethers
359 (PBDEs) and specific phthalates) in electrotechnical products is a source of concern in current
360 and proposed regional legislation.
361 The purpose of the IEC 62321 series is therefore to provide test methods that will allow the
362 electrotechnical industry to determine the levels of certain substances of concern in
363 electrotechnical products on a consistent global basis.
364 This second edition of IEC 62321-8 describes the test method for specific phthalates based on
365 REACH Annex XVII, RoHS Directive and US CPSIA in electrotechnical products by gas
366 chromatography-mass spectrometry (GC-MS) and the GC-MS using a pyrolyser/thermal
367 desorption (TD) techniques in the normative section.
368 In addition, information on ion attachment mass spectrometry (IAMS) and liquid
369 chromatography – mass spectrometry (LC-MS) are provided in Annex A (informative) and
370 Annex B (informative), respectively.
371 WARNING – Persons using this document should be familiar with normal laboratory practice.
372 This document does not purport to address all of the safety problems, if any, associated with
373 its use. It is the responsibility of the user to establish appropriate safety and health practices
374 and to ensure compliance with any national regulatory conditions.
