标准范围

IEC 62321-2:20 21提供了取样策略以及电工产品样品的机械制备。这些样品可用于分析测试，以确定IEC 62321系列其他部分测试方法中描述的某些物质的水平。对物质的限制因地理区域而异，并且可以定期更新。本文件描述了在测定任何相关物质之前获取和制备样品的通用过程。本文档不提供:-对可归类为电工产品的每一种产品的全面指导。由于电工零件种类繁多，具有各种结构和组成，随着工业中的不断创新，试图提供用于每种类型零件的分离的程序是不现实的；-关于收集产品中某些物质的额外信息的其他途径的指南，尽管所收集的信息与本文件中的取样策略相关；-与电工产品（如含汞开关）和回收行业（如如何处理阴极射线管或安全移除电池）有关的安全拆卸和机械断开说明。含汞荧光灯的分离和机械制样见IEC 62554；-包装和包装材料的取样程序；-测定某些物质含量的分析程序。这由其他标准（例如IEC 62321系列的其他部分）涵盖，在本文档中称为“测试标准”；-评估遵守情况的准则。根据IEC指南108，本文件具有水平标准的地位。IEC 62321-2:20 21取消并取代2013年发布的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)参考IEC 62321系列，而不是IEC 62321系列的各个部件列表。b)更新图1中的流程图。第4条的重组和附件A中示例的更新。c)调整某些零件和材料的风险水平，以反映最近的技术发展和材料变化。更新表B.1，纳入邻苯二甲酸盐的风险水平。为聚合物材料中的其他物质（如六溴环十二烷、多环芳烃）创建表B.2。

IEC 62321-2:2021 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 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.
IEC 62321-2:2021 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.
c) Adjustment of the risk levels of certain parts and materials to reflect the recent technology development and material change. Update of Table B.1 to include the risk levels of phthalates. Creation of Table B.2 for other substances (e.g. HBCDD, PAH) in polymeric materials.
