标准范围

IEC 61800-5-3:20 21是一项产品标准，从功能安全考虑、电气安全和环境条件方面为安全相关编码器（编码器（SR））的设计和开发、集成和验证规定了要求并提出了建议。它适用于编码器（SR），即作为PDS（SR）一部分的传感器。本文档也可以参考并用于任何其他安全相关应用中的编码器(SR)，例如安全相关位置监测。本文件适用于要求编码器功能安全且编码器（SR）主要在高需求或连续模式下运行的情况。IEC 61800-5-2:20 16对PDS（SR）的要求适用于编码器（SR）。本文档包括编码器（SR）的附加或不同要求。它根据IEC 61508（所有部分）的框架阐述了编码器（SR）的安全相关考虑因素，并介绍了编码器（SR）作为安全相关系统的子系统的要求。其旨在促进编码器(SR)的电气/电子/可编程电子(E/E/PE)和机械部件的实现，其与编码器(SR)的安全子功能的安全性能有关。

IEC 61800-5-3:2021, which is a product standard, specifies requirements and makes recommendations for the design and development, integration and validation of safety-related encoder (Encoder(SR)) in terms of their functional safety considerations, electrical safety and environmental conditions. It applies to Encoder(SR), being sensors as part of a PDS(SR). This document can also be referred to and used for Encoder(SR) in any other safety-related application, for example safety-related position monitoring.
This document is applicable where functional safety of an encoder is claimed and the Encoder(SR) is operating mainly in the high demand or continuous mode. The requirements of IEC 61800-5-2:2016 for PDS(SR) apply to Encoder(SR) as applicable.
This document includes additional or different requirements for Encoder(SR). It sets out safety-related considerations of Encoder(SR) in terms of the framework of IEC 61508 (all parts), and introduces requirements for Encoder(SR) as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/electronic/programmable electronic (E/E/PE) and mechanical parts of an Encoder(SR) in relation to the safety performance of safety sub-function(s) of an Encoder(SR).
