Determination of certain substances in electrotechnical products - Part 6: Polybrominated biphenyls and polybrominated diphenyl ethers in polymers by gas chromatography-mass spectrometry (GC-MS) - Ion Attachment Mass Spectrometry (IAMS) and High Pressure Liquid Chromatography - Ultra Violet detection (HPLC-UV) (IEC 62321-6:2015)

This Part of IEC 62321 specifies one normative and two informative techniques for the
determination of polybrominated biphenyls (PBB) and diphenyl ethers (PBDE) in polymers of
electrotechnical products.
The gas chromatography–mass spectrometry (GC-MS) test method is suitable for the
determination of monobrominated to decabrominated biphenyls (PBB) and monobrominated to
decabrominated diphenyl ethers (PBDE).
Annexes A and C contain methods using ion attachment mass spectrometry (IAMS) coupled
with direct injection probe (DIP) and high-pressure liquid chromatography coupled to photo
diode array ultra violet detector (HPLC-PDA/UV). These techniques have utility as fast,
qualitative or semi-quantitative type methods but are subject to limitations including
interferences or the number or type of PBB and PBDE compounds within their scope.
The ion attachment mass spectrometry (IAMS) technique is limited to the determination of
decabromo biphenyl and technical mixtures of decabromodiphenyl ether, octabromodiphenyl
ether, and pentabromo diphenyl ether flame retardant compounds. The determination of other
PBBs or PBDEs by this method has not been evaluated.
The high-pressure liquid chromatography technique is limited to the determination of technical
mixtures of decabromodiphenyl ether, octabromo diphenyl ether, decabromo biphenyl and
octabromo biphenyl technical flame retardants. The determination of other PBBs or PBDEs by
this method has not been evaluated.
These test methods have been evaluated for use with PS-HI (polystyrene, high-impact) and
PC/ABS (a blend of polycarbonate and acrylonitrile butadiene styrene) containing individual
PBDEs between 20 mg/kg to 2 000 mg/kg and total PBDEs between 1 300 mg/kg to 5 000
mg/kg as depicted in this standard including in Annex F. The use of these methods for other
polymer types, PBBs or other PBDE compounds or concentration ranges other than those
specified above has not been specifically evaluated.

Verfahren zur Bestimmung von bestimmten Substanzen in Produkten der Elektrotechnik - Teil 6: Polybromierte Biphenyl- und Diphenylether in Polymeren durch Gaschromatographie-Massenspektrometrie (GC-MS) (IEC 62321-6:2015)

Détermination de certaines substances dans les produits électrotechniques - Partie 6: Diphényles polybromés et diphényléthers polybromés dans des polymères par chromatographie en phase gazeuse, Spectrométrie de masse (GC-MS) - Spectrométrie de masse à ions attachés (IAMS) et chromatographie liquide à haute pression - Détection des ultraviolets (HPLC-UV) (IEC 62321-6:2015)

L'IEC 62321-6:2015 spécifie une technique normative et deux techniques informatives de détermination de diphényles polybromés (PBB) et de diphényléthers polybromés (PBDE) dans des polymères de produits électrotechniques. Les méthodes de test sont: - La méthode d'essai de chromatographie en phase gazeuse - spectrométrie de masse (GC-MS); - La technique de la spectrométrie de masse à ions attachés (IAMS) et - La technique de la chromatographie liquide à haute pression. La première édition de l'IEC 62321:2008 était une norme "autonome" qui incluait une introduction, une vue d'ensemble des méthodes d'essai, la préparation mécanique des échantillons et différents articles relatifs à des méthodes d'essai. Cette première édition de l'IEC 62321-6 remplace en partie l'IEC 62321:2008, formant une révision structurelle et remplaçant en général l'Annexe A.

Določevanje posameznih substanc v elektrotehniških izdelkih - 6. del: Določevanje polibromiranih bifenilov in polibromiranih difeniletrov v polimerih s plinsko kromatografijo-masno spektrometrijo (GC-MS) - Masna spektrometrija s pripenjanjem iona (IAMS) in tekočinska kromatografija visoke ločljivosti z UV-detekcijo (HPLC-UV) (IEC 62321-6:2015)

Ta del standarda IEC 62321 določa eno normativno in dve informativni tehniki za določanje polibromiranih bifenilov (PBB) in difenil etrov (PBDE) v polimerih elektrotehničnih izdelkov.
Preskusna metoda plinske kromatografije z masno spektrometrijo (GC-MS) je primerna za določanje monobromiranih do dekabromiranih bifenilov (PBB) in monobromiranih do dekabromiranih difenil etrov (PBDE).
Dodatka A in C vsebujeta metode, v katerih se uporablja masna spektrometrija s pripenjanjem iona (IAMS) in sonda direktnega vbrizgavanja (DIP) ter visokotlačna tekočinska kromatografija v povezavi z UV-detekcijo (HPLC-PDA/UV). Te tehnike so uporabne kot hitre, kakovostne in semi-kvantitativne metode, vendar so predmet omejitev, ki vključujejo motnje ali število oz. vrsto spojin PBB in PBDE v okviru njihovega področja. Tehnika masne spektrometrije s pripenjanjem iona (IAMS) je omejena na določanje dekabromobifenila in na ogenj odpornih tehničnih mešanic dekabromodifeniletra, oktabromodifeniletra in pentabromodifeniletra. Določevanje drugih substanc PBB ali PBDE s to metodo ni ocenjeno. Tehnika visokotlačne tekočinske kromatografije je omejena na določevanje na ogenj odpornih tehničnih mešanic dekabromodifeniletra, oktabromodifeniletra, dekabromobifenila in oktabromobifenila. Določevanje drugih substanc PBB ali PBDE s
to metodo ni ocenjeno. Te preskusne metode so bile ocenjene za uporabo s PS-HI (polistiren visoke udarne žilavosti) in PC/ABS (mešanico polikarbonata in akrilonitril butadien stirena), ki vsebujejo posamezne substance PDBE od 20 mg/kg do 2000 mg/kg in skupnih PDBE od 1 300 mg/kg do 5000 mg/kg, kot je opisano v tem standardu, vključno z Dodatkom F. Uporaba teh metod za druge vrste polimerov, spojin PBB ali drugih spojin PBDE ali koncentracij, razen zgoraj navedenih, ni bila posebej ovrednotena.

DETERMINATION OF CERTAIN SUBSTANCES
IN ELECTROTECHNICAL PRODUCTS –
Part 6: Polybrominated biphenyls and polybrominated diphenyl ethers
in polymers by gas chromatography–mass spectrometry (GC-MS)
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

International Standard IEC 62321-6 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 62321-6 is a partial replacement of IEC 62321:2008, forming a

structural revision and generally replacing Annex A.

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.
