标准摘要
[中文适用范围]: IEC 61496-2:2020规定了对设计、制造和测试光敏安全防护设备(ESPE)的要求,该设备专门用于作为安全相关系统的一部分检测人员,并采用有源光敏保护器件(AOPDs)作为传感功能。特别关注确保实现适当的安全相关性能的 features。ESPE可以包括可选的安全相关功能,其要求见IEC 61496-1:2020和本文件的附件A。本文件不规定任何特定应用中检测区域的尺寸或配置及其相对于危险部件的布置,也不定义机器的任何危险状态。它仅限于ESPE的功能及其与机器的接口。本文件排除了使用波长在400 nm至1 500 nm范围之外的辐射的AOPDs。本文件可能与保护人员以外的应用有关,例如保护机器或产品免受机械损伤。在这些应用中,可能需要额外的要求,例如当传感功能要识别的材料具有不同于人员的属性时。本文件不处理电磁干扰(EMC)发射要求。 [外文原描述]: IEC 61496-2:2020 specifies requirements for the design, construction and testing of electro-sensitive protective equipment (ESPE) designed specifically to detect persons as part of a safety-related system, employing active opto-electronic protective devices (AOPDs) for the sensing function. Special attention is directed to features which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A of IEC 61496-1:2020 and of this document. This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine. Excluded from this document are AOPDs employing radiation at wavelengths outside the range 400 nm to 1 500 nm. This document can be relevant to applications other than those for the protection of persons, for example, the protection of machinery or products from mechanical damage. In those applications, additional requirements can be necessary, for example, when the materials that are to be recognized by the sensing function have different properties from those of persons. This document does not deal with electromagnetic compatibility (EMC) emission requirements. IEC 61496-2:2020 cancels and replaces the third edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Requirements and test procedures in Part 2 that were found to be common to all ESPEs have been moved to Part 1. Test procedures that are dependent on the sensing technology remain in Part 2.
