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].
