标准摘要
[中文适用范围]： 第 1 部分的本条款由以下内容替代： IEC 61496 的本部分规定了电敏防护设备 (ESPE) 的设计、构造和测试要求，该设备专门设计用于检测人员，作为安全相关系统的一部分@采用主动用于传感功能的光电保护装置（AOPD）。特别关注确保实现适当的安全相关性能的功能。 ESPE 可以包括可选的安全相关功能@，其要求在 IEC 61946-1:2012 和本部分的附录 A 中给出。 IEC 61496 的这一部分没有指定检测区域的尺寸或配置及其与任何特定应用的危险部件相关的配置，也没有指定任何机器的危险状态的构成。它仅限于 ESPE 的功能及其与机器的接口方式。本部分不包括使用 400 nm 至 1500 nm 范围之外波长辐射的 AOPD。 IEC 61496 的这一部分可能与人身保护以外的应用相关@例如@保护机械或产品免受机械损坏。在这些应用中，可能需要额外的要求，例如，当传感功能识别的材料具有与人不同的特性时。 IEC 61496 的这一部分不涉及 EMC 发射要求。 [外文原描述]： IEC 61496-2:2013 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 may include optional safety-related functions, the requirements for which are given in Annex A of IEC 61946-1:2012 and of this part. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision and includes the following significant technical changes with respect to the previous edition: - Requirements have been corrected and made easier to understand. - Test procedures have been revised to make them easier to perform and to improve repeatability. - Guidance is provided for the evaluation and verification of AOPDs using design techniques for which the test procedures of this part are not sufficient. This publication is to be read in conjunction with IEC 61496-1:2012 .
