标准范围

IEC指南121:2023规定了标准编写者确定其标准中的评估方法是否可用于获得产品环境性能的指示并确保此类评估可信的原则、要求和指南。本指南适用于涵盖新产品环境性能的标准，并酌情适用于涵盖第二人生产品（如翻新或再制造）环境性能的标准。因此，本指南旨在确保标准作者开发的评估方法是可信的。环境相关绩效评估方法的可信度是通过考虑所有相关原则来确定的，即代表性、测量重复性、测量再现性、测量准确性、测试成本以及规避。与环境相关的性能评估方法可以存在于许多IEC标准中（例如，涵盖产品性能方面的标准），而不仅仅是那些关注环境的标准。本指南也适用于这些人。本指南不适用于包含未通过测试进行评估的环境相关性能评估方法的标准（例如，通过检查或模拟进行评估）。它也不适用于与环境无关的其他方面，如EMC和EMF。

IEC GUIDE 121:2023 specifies principles, requirements, and guidance for standard writers to identify whether an assessment method in their standard can be used to obtain an indication of the environmental performance of a product and to ensure that such assessment is credible.
This Guide applies to standards covering environmental performance of new products and as appropriate to standards covering environmental performance of second life products (e.g., refurbished or remanufactured).
This Guide is therefore intended to ensure that assessment methods developed by standard writers are credible. The credibility of an environmentally relevant performance assessment method is determined by taking into account all the related principles, namely representativeness, measurement repeatability, measurement reproducibility, measurement accuracy, cost of testing, as well as circumvention.
Environmentally relevant performance assessment methods can be present in many IEC standards (e.g., standards covering performance aspects of products), and not only those focused on the environment. This Guide will be applicable to those as well.
This Guide is not applicable to standards containing environmentally relevant performance assessment methods that are not assessed by test (e.g., assessment by inspection or simulation). Nor is it applicable to other aspects not linked to environment, such as EMC and EMF.
