电气电子产品和系统生命周期评估的产品类别规则

[中文适用范围]： IEC 63366:2025 为电气和电子产品及系统（EEPS）定义了产品类别规则（PCR），用于制定电气和电子产品及系统（EEPS）的 III 型环境声明。该标准规定了在环境声明背景下进行生命周期评估（LCA）的流程和要求。本文件提供了以下方面的通用规则：a）生命周期评估（LCA），包括开发默认情景的要求；b）生命周期评估报告；c）产品特定规则（PSR）的制定。本文件还提供了有关环境声明的进一步指南。生命周期评估的原则和框架基于 ISO 14040 和 ISO 14044，因此本文件不包含这些内容。产品类别规则（PCR）通过补充产品特定规则（PSR）加以完善，这些规则进一步明确了产品特定情境下的功能单位和默认情景。因此，本文件还为相应技术委员会制定产品特定规则（PSR）提供了指导。根据 IEC 指南 108，本文件具有横向出版物的地位。根据 IEC 指南 108，该通用基本横向标准旨在作为产品委员会制定产品特定规则（PSR）标准的起点。产品委员会在产品特定规则（PSR）标准中制定的具体要求将优先于本标准中的要求。当产品委员会中没有可用的产品特定规则（PSR）时，生命周期评估从业者可以应用本通用基本横向标准，并记录补充规格。 [外文原描述]： IEC 63366:2025 defines product category rules (PCR) for electrical and electronic products and systems (EEPS) to develop Type III environmental declarations for electrical and electronic products and systems (EEPS). It specifies the process and requirements on how to conduct life cycle assessment (LCA) in the context of environmental declarations. This document provides common rules for: a) LCA, including the requirements for developing default scenarios; b) the LCA report; c) the development of PSR. This document provides further guidelines for environmental declarations. The LCA principles and framework are based on ISO 14040 and ISO 14044, and are therefore out of scope of this document. PCR is complemented by additional product-specific rules (PSR), which further define, for example, functional units and default scenarios in the product-specific context. Therefore, this document also provides guidance on how to develop PSR in corresponding technical committees. This document has the status of a horizontal publication in accordance with IEC Guide 108. In accordance with IEC Guide 108, this generic essential horizontal standard is intended for use by product committees as a starting point in preparing PSR standards. Specific requirements developed by product committees in PSR standard take precedence over requirements in this standard. When there is no PSR available in a product committee, this generic essential horizontal standard could be applied by LCA practitioners with recorded complementary specifications.
