IEC 62321-2:2021 pdf download,Determination of certain substances in electrotechnical products
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 ] 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 1 08 [2].
3 Terms, definitions and abbreviated terms
3.1 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 62321 -1 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1.1 composite testing testing of two or more materials as a single sample that could be mechanically disjointed if necessary 3.1.2 certain substance substance subject to test methods developed or under development in IEC 62321 (all parts), such as cadmium, lead, mercury, hexavalent chromium, polybrominated biphenyl, polybrominated diphenyl ether, phthalates Note 1 to entry: IEC 62321 -1 includes test methods for the evaluation of each of the substances identified in the definition above. 3.1.3 disassembly process whereby an item is taken apart in such a way that it could subsequently be reassembled and made operational 3.1.4 disjointment process whereby materials are separated by mechanical means such that the item cannot subsequently be reassembled to make it operational 3.1.5 homogeneous material one material of uniform composition throughout or a material, consisting of a combination of materials, that cannot be disjointed or separated into different materials by mechanical actions such as unscrewing, cutting, crushing, grinding and abrasive processes [SOURCE: EU RoHS DIRECTIVE 201 1 /65/EU [3]] 3.1.6 sampling process of obtaining a sample of an electrotechnical product intended for the analysis for the presence of certain substance(s)
4 Introduction to sampling
4.1 Introductory remarks Testing of certain substances in products is performed for different reasons including: – commercial release of a product (e.g. in fulfillment of a contractual agreement between an OEM and a part manufacturer); – assessment of conformity with regulatory limits; – forensics, in case non-conformity is questioned (why the product does not satisfy contractual or legal requirements, when did this happen, and how many products are affected?). Appropriate sampling is crucial when analysing electrotechnical products for the presence of certain substances. The strategy and process of sampling are often as important as the analytical test itself. Hence an effective sampling strategy requires a clear understanding of the electrotechnical product, reasons for the analysis and the requirements to be met. 4.2 Requirements for certain substances While many regulators, industries and other stakeholders have their own, often non-uniform requirements for certain substances, it is not the intention of this document to discuss fully these differences. However, awareness of different requirements for certain substances is an important step in the sampling strategy. Subclause 4.2 highlights the differences in requirements concerning certain substances.
