[中文适用范围]： 本部分IEC 62257为灯具和照明器具的产品规范建立了框架，作为评估特定环境下质量的基础。产品规范包括质量标准的最低要求、保修要求和/或性能标准。产品根据测试结果和其他产品信息与规范进行比较。产品规范框架灵活，可以适应不同组织和机构的目标。 本文件适用于具有以下特性的离网电力系统的灯具和照明器具： - 电源为交流或直流： - 交流标称电压最高为250V； - 直流标称电压最高为48V。 - 光源为CFL、线性荧光灯或LED。 - 灯具或照明器具的操作不需要测试实验室提供的任何组件，除了灯座、电线、连接器和电源。 - 灯具或照明器具不包括电池或能源（例如光伏模块或机电发电机）。 如果灯具与灯具一起包装，则灯具包括在“照明器具”的定义中。不带灯具的灯具不包括在本文件的范围内。 [外文原描述]： IEC TS 62257-12-1:2020 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 TS 62257-12-1:2020 establishes the framework for creating a product specification for lamps and lighting appliances to serve as the basis for evaluating quality for a particular context. Product specifications include minimum requirements for quality standards, warranty requirements, and/or performance criteria. Products are compared to specifications based on test results and other information about the product. The product specification framework is flexible and can accommodate the goals of diverse organizations and institutions. This third edition cancels and replaces the second edition published in 2015. This edition includes the following significant technical changes with respect to the previous edition. - Annex A and Annex B were combined into a single Annex A to eliminate duplicate tables and simplify the document.
