标准摘要
[中文适用范围]： IEC 62321-3-1:2026 RLV 包含 IEC 国际标准的正式版本及其标红修订版。标红修订版仅提供英文文本，便于快速、便捷地比对正式标准与其前一版本之间的所有变更。 IEC 62321-3-1:2026 规定了电子电气产品中均匀材料内特定物质的筛查分析，具体涉及：铅（Pb）、汞（Hg）、镉（Cd）、总铬（Cr）、总溴（Br）、总磷（P，假设其来源与三氯乙基磷酸酯 TCEP（CAS 115‑96‑8）、三二甲苯基磷酸酯（CAS 25155‑23‑1）相关）、总氯（Cl，假设其来源与短链氯化石蜡 SCCP（CAS 85535‑84‑8）及 TCEP（CAS 115‑96‑8）相关）、三丁基锡（TBTC，CAS 1461‑22‑9）、总锡（Sn，假设其来源与受限有机锡化合物相关）、总锑（Sb，假设其来源与烧锆矿 Pyrochlore 及锑铅黄（CAS 8012‑00‑8）相关）。该标准采用 X 射线荧光光谱法（XRF）进行分析。 相较于 IEC 62321-3-1:2013 及 IEC 62321:2008 的前一版本，本版本包含以下重要技术变更： a) 本第二版增加了若干元素作为新增物质的指标进行分析，元素选择依据为 IEC TR 62936:2016。同时，文档还就采用相同方法筛查关键原材料（CRMs）含量提供了相关说明。 本文件已按照 ISO/IEC 导则第 1 部分的规定，被确立为水平文件。 [外文原描述]： IEC 62321-3-1:2026 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 62321-3-1:2026 describes the screening analysis of substances, specifically lead (Pb), mercury (Hg), cadmium (Cd), total chromium (Cr), total bromine (Br), total phosphorus (P), assuming the source of P is related to TCEP (CAS 115‑96‑8), Trixylyl-phosphate (CAS 25155‑23‑1), total chlorine (Cl), assuming the source of Cl is related to SCCP (CAS 85535‑84‑8), TCEP (CAS 115‑96‑8) , TBTC (CAS 1461‑22‑9), total tin (Sn), assuming the source of Sn is related to restricted organo-tin compounds, total antimony (Sb), assuming the source of Sb is related to Pyrochlore, and antimony lead yellow (CAS 8012‑00‑8) in uniform materials found in electrotechnical products, using the analytical technique of X‑ray fluorescence (XRF) spectrometry. This edition includes the following significant technical changes with respect to the previous editions of IEC 62321-3-1:2013 and IEC 62321:2008: a) This second edition of IEC 62321-3-1 includes the analysis of additional elements as indicators for additional substances. The selection is based on IEC TR 62936:2016. There are also comments about using the same methology for screening for content of critical raw materials (CRMs). This document has been given the status of a horizontal document in accordance with the ISO/IEC Directives, Part 1.
