标准摘要
[中文适用范围]: IEC 60947-5-3 系列提供了在 IEC 60947-5-2 中给出的要求的补充要求。它涉及具有规定故障行为(PDDB)的接近装置在故障条件下的故障性能方面。它不解决特定应用所需的其他任何特征。本标准不涵盖具有模拟输出的接近装置。本标准不处理任何特定的声学噪声要求,因为控制电路装置和开关元件的噪声排放不被视为相关危害。对于需要在其他标准中处理的其他特征的应用中使用的 PDDB,所有相关标准的要求均适用。单独使用本标准并不能证明适用于实施任何特定安全相关功能。特别是,本标准不提供 PDDB 致动特性或减少设备之间相互干扰影响(例如编码目标)的手段的要求。因此,这些以及任何其他特定应用的要求必须在本标准的要求之外进行考虑。注 1:由于其故障条件下的行为,PDDB 可用作联锁装置(见 ISO 14119)。注 2:用于检测人员的安全敏感保护设备的要求在 IEC 61496 系列中给出。 [外文原描述]: IEC 60947-5-3:2013 series provides additional requirements to those given in IEC 60947-5-2. It addresses the fault performance aspects of proximity devices with a defined behaviour under fault conditions (PDDB). It does not address any other characteristics that can be required for specific applications. This second edition replaces the first edition published in 1999 and its amendment published in 2005. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) general principles of IEC 61508 series; b) classification according to the requirements of IEC 62061; c) classification according to ISO 13849-1. This publication is to be read in conjunction with IEC 60947-1:2007 and IEC 60947-5-2:2007 .
