[中文适用范围]： 本文件规定了与电工行业组织及其供应商产品和配件材料声明相关的程序、内容和形式。产品使用过程中的工艺化学品、排放物和产品包装材料不在本文件范围内。 本文件的主要用途是提供供应链上下游的数据，使组织能够： - 根据物质限制合规要求评估产品， - 在其环保设计过程和所有产品生命周期阶段使用此信息。 本文件规定了强制性声明要求，并提供了可选的声明要求。 本文件未建议在供应链中捕获材料声明数据的具体方法或流程，但提供了用于在供应链内传输信息的数据格式。组织可灵活确定最合适的方法来捕获材料声明数据，而不影响数据效用和质量。本文件旨在允许基于工程判断、供应商材料声明和/或抽样测试的报告。 [外文原描述]： IEC 62474:2018 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 62474:2018 specifies the procedure, content, and form relating to material declarations for products of companies operating in and supplying the electrotechnical industry. Process chemicals and emissions during product use are not in the scope of this International Standard. It provides data to downstream manufacturers that: - allows them to assess products against substance restriction compliance requirements; - they can use in their environmentally conscious design process and across all product life cycle phases. A database associated with this document is available at http://std.iec.ch/iec62474 . It contains the list of: - Declarable substance groups and declarable substances; - Reference Substances; - Material classes; - XML schema for data format and exchange and the accompanying developer table. IEC 62474:2018 cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. IEC 62474:2018 includes the following significant technical changes with respect to the previous edition: a) The material classes and exemption lists capabilities have been improved. b) The introduction and scope have new diagrams and information to give a better overview of the standard and identify what information is mandatory, optional or conditionally mandatory. c) Definitions have been added. Minimum requirements to be in conformance with the IEC 62474 standard are defined, including XML format as the officially accepted format. By defining an authority, list identity and list version, the standard format could be used for lists other than the IEC 62474 database. d) Terms have been aligned for consistency throughout the document. For example, the “IEC 62474 database” was previously referred to as “IEC 62474 database”, “IEC 62474”, “IEC 62474 Database”, “IEC 62474 DB”. e) The annexes have been removed as they are now contained within documents managed by the validation team 62474 (VT 62474). Annex A (Annex B in the previous edition) is provided for non-XML users as a reference only.
