Determination of certain substances in electrotechnical products - Part 2: Disassembly, disjointment and mechanical sample preparation

This part of IEC 62321 provides strategies of sampling along with the mechanical preparation of samples from electrotechnical products. These samples can be used for analytical testing to determine the levels of certain substances as described in the test methods in other parts of the IEC 62321 series. Restrictions for substances will vary between geographic regions and can be updated on a regular basis. This document describes a generic process for obtaining and preparing samples prior to the determination of any substance of concern. This document does not provide: - full guidance on each and every product that could be classified as electrotechnical product. Since there is a huge variety of electrotechnical parts, with various structures and compositions, along with the continuous innovations in the industry, it is unrealistic to attempt to provide procedures for the disjointment of every type of part; - guidance regarding other routes to gather additional information on certain substances in a product, although the information collected has relevance to the sampling strategies in this document; - safe disassembly and mechanical disjointment instructions related to electrotechnical products (e.g. mercury-containing switches) and the recycling industry (e.g. how to handle CRTs or the safe removal of batteries). See IEC 62554 [1] 1 for the disjointment and mechanical sample preparation of mercury-containing fluorescent lamps; - sampling procedures for packaging and packaging materials; - analytical procedures to measure the levels of certain substances. This is covered by other standards (e.g. other parts of the IEC 62321 series), which are referred to as "test standards" in this document; - guidelines for assessment of compliance. This document has the status of a horizontal standard in accordance with IEC Guide 108 [2].

Verfahren zur Bestimmung von bestimmten Substanzen in Produkten der Elektrotechnik – Teil 2: Demontage, Zerlegung und mechanische Probenvorbereitung

Détermination de certaines substances dans les produits électrotechniques - Partie 2: Démontage, défabrication et préparation mécanique de l'échantillon

L'IEC 62321-2:2021 fournit des stratégies d'échantillonnage ainsi que de préparation mécanique d'échantillons de produits électrotechniques. Ces échantillons peuvent être utilisés pour un essai analytique visant à déterminer les niveaux de certaines substances, comme cela est décrit dans les méthodes d'essai des autres parties de la série IEC 62321. Les restrictions concernant les substances varient selon les régions géographiques et peuvent régulièrement être mises à jour. Le présent document décrit un processus générique qui permet d'obtenir et de préparer des échantillons avant de déterminer toute substance d’intérêt. Le présent document ne fournit pas: – de recommandations exhaustives pour l’ensemble des produits qui peuvent être considérés comme produits électrotechniques. Étant donné qu'il existe une très grande diversité de pièces électrotechniques, avec différentes structures et compositions, ainsi que des innovations continues de l'industrie, il est irréaliste de tenter de fournir des procédures pour la défabrication de chaque type de pièce; – de recommandations concernant d'autres voies de collecte d’informations supplémentaires sur certaines substances présentes dans un produit, bien que les informations recueillies soient pertinentes pour les stratégies d'échantillonnage du présent document; – d’instructions pour un démontage et une défabrication mécanique sécurisés dans le domaine des produits électrotechniques (par exemple des commutateurs qui contiennent du mercure) et de l'industrie du recyclage (par exemple, comment manipuler des TRC (tubes à rayons cathodiques) ou éliminer des batteries en toute sécurité). Voir l'IEC 62554 pour la défabrication et la préparation mécanique d'échantillons issus de lampes fluorescentes qui contiennent du mercure; – de procédures d'échantillonnage pour l’emballage et les matériaux d’emballage; – de procédures analytiques qui permettent de mesurer les niveaux de certaines substances. Ceci est couvert par d'autres normes (par exemple d'autres parties de la série IEC 62321) qui sont appelées “normes d'essai” dans le présent document; – de lignes directrices d'évaluation de la conformité. Le présent document a le statut d'une norme horizontale conformément au Guide 108 de l'IEC. L'IEC 62321-2:2021 annule et remplace la première édition parue en 2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente. a) Référence à la série IEC 62321 en lieu et place des normes IEC 62321 individuelles. b) Mise à jour de l’organigramme de la Figure 1. Restructuration de l'Article 4 et des exemples de l'Annexe A en conséquence. c) Ajustement des niveaux de risque de certaines parties et matériaux afin de refléter les dernières avancées technologiques et changements de matériaux. Mise à jour du Tableau B.1 pour inclure les niveaux de risque liés aux phtalates. Création du Tableau B.2 pour les autres substances (HBCDD, PAH, par exemple) présentes dans les matériaux polymères.

Določevanje posameznih snovi v elektrotehničnih izdelkih - 2. del: Razstavljanje, odklop in mehanska priprava vzorca

Ta del standarda IEC 62321 določa strategije vzorčenja skupaj z mehansko pripravo vzorcev iz elektrotehničnih izdelkov. Te vzorce je mogoče uporabiti za analitično preskušanje za določitev vsebnosti nekaterih snovi, kot je opisano v preskusnih metodah v drugih delih skupine standardov IEC 62321. Omejitve za snovi se razlikujejo med geografskimi območji in se lahko redno posodabljajo. Ta dokument opisuje splošen postopek za pridobitev in pripravo vzorcev pred določitvijo katere koli zadevne snovi. Ta dokument ne podaja: – popolnih smernic za vsak izdelek, ki ga je mogoče razvrstiti kot elektrotehnični izdelek. Ker hkrati z nenehnimi industrijskimi inovacijami obstaja veliko različnih elektrotehničnih delov z različno konstrukcijo in sestavo, je nerealno, da bi poskušali zagotoviti postopke za razstavljanje vsakega tipa dela pri stikališčih; – smernic glede drugih poti za zbiranje dodatnih informacij o nekaterih snoveh v izdelku, čeprav so zbrane informacije pomembne za strategije vzorčenja v tem dokumentu; – navodil za varno razstavljanje in mehansko razstavljanje pri stikališčih, povezanih z elektrotehničnimi izdelki (npr. stikala, ki vsebujejo živo srebro) in reciklažno industrijo (npr. kako ravnati z zasloni CRT ali varno odstraniti baterije). Glej standard IEC 62554 [1] 1 za razstavljanje pri stikališčih in pripravo mehanskih vzorcev fluorescenčnih sijalk, ki vsebujejo živo srebro; – postopkov vzorčenja za embalažo in embalažne materiale; – analitičnih postopkov za merjenje vsebnosti nekaterih snovi. To je zajeto v drugih standardih (npr. drugih delih skupine standardov IEC 62321), ki so navedeni kot »preskusni standardi« v tem dokumentu; – smernic za oceno skladnosti. Ta dokument ima status usklajenega horizontalnega standarda v skladu z vodilom IEC 108 [2].

DETERMINATION OF CERTAIN SUBSTANCES
IN ELECTROTECHNICAL PRODUCTS –
Part 2: Disassembly, disjointment and mechanical sample preparation
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 62321-2 has been prepared by IEC technical committee 111: Environmental

standardization for electrical and electronic products and systems. It is an International

Standard.

This second edition cancels and replaces the first edition published in 2013. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) Reference to the IEC 62321 series instead of to a list of individual parts of the IEC 62321

series.

b) Update of the flow chart in Figure 1. Restructure of Clause 4 and update of examples in

Annex A.

INTRODUCTION

The widespread use of electrotechnical products has drawn increased attention to their impact

on the environment. In many countries this has resulted in the adaptation of regulations

affecting wastes, substances and energy use of electrotechnical products.

The use of certain substances in electrotechnical products is a source of either concern or

importance in current and proposed regional legislations.

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 in electrotechnical

products on a consistent global basis. This document, as an important part of the IEC 62321

series, covers strategies of sampling along with the mechanical preparation.
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.

DETERMINATION OF CERTAIN SUBSTANCES
IN ELECTROTECHNICAL PRODUCTS –
Part 2: Disassembly, disjointment and mechanical sample preparation
1 Scope

This part of IEC 62321 provides strategies of sampling along with the mechanical preparation

of samples from electrotechnical products. These samples can be used for analytical testing to

determine the levels of certain substances as described in the test methods in other parts of

the IEC 62321 series. Restrictions for substances will vary between geographic regions and

can be updated on a regular basis. This document describes a generic process for obtaining

and preparing samples prior to the determination of any substance of concern.
This document does not provide:

– full guidance on each and every product that could be classified as electrotechnical product.

Since there is a huge variety of electrotechnical parts, with various structures and

compositions, along with the continuous innovations in the industry, it is unrealistic to

attempt to provide procedures for the disjointment of every type of part;

– guidance regarding other routes to gather additional information on certain substances in a

product, although the information collected has relevance to the sampling strategies in this

document;

– safe disassembly and mechanical disjointment instructions related to electrotechnical

products (e.g. mercury-containing switches) and the recycling industry (e.g. how to handle

CRTs or the safe removal of batteries). See IEC 62554 [1] for the disjointment and

mechanical sample preparation of mercury-containing fluorescent lamps;
– sampling procedures for packaging and packaging materials;

– analytical procedures to measure the levels of certain substances. This is covered by other

standards (e.g. other parts of the IEC 62321 series), which are referred to as "test

standards" in this document;
– guidelines for assessment of compliance.

This document has the status of a horizontal standard in accordance with IEC Guide 108 [2].
