机械安全 - 电敏保护设备第1部分:一般要求和测试

[中文适用范围]： 本部分IEC 61496规定了针对特定设计用于作为安全相关系统的一部分检测人员或部分人员的非接触式电敏感防护设备（ESPE）的设计、构造和测试的一般要求。特别关注确保实现适当的安全相关性能的功能和设计要求。ESPE可以包括可选的安全相关功能，其要求见附录A。注：非接触式意味着感应时不需要物理接触。本文档应与IEC 61496的后续部分一起使用，该后续部分提供基于感应技术的具体要求。示例：本文档与IEC 61496-2一起用于AOPD（主动光敏防护设备）；本文档与IEC 61496-3一起用于AOPDDR（带光幕的主动光敏防护设备）。当不存在涵盖感应技术的部分时，使用IEC TS 62998-1。当IEC 61496系列不包含所有必要条款时，使用IEC TS 62998-1。除了IEC TS 62998-1之外，结合IEC 61496系列涵盖的那些方面也是一种额外的可能性。本文档不规定检测区及其相对于任何特定应用中危险的位置的维度或配置，也不规定任何机器的危险状态构成什么。它仅限于ESPE的功能以及它与机器接口的方式。虽然可以使用数据接口来控制可选的安全相关ESPE功能（附录A），但本文档不提供具体要求。这些安全相关功能的要求可以通过查阅其他标准（例如IEC 61508（所有部分）、IEC 62046、IEC 62061和ISO 13849-1）来确定。本文档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，可能适用不同的要求，例如当感应功能必须识别的材料与人员的材料具有不同属性时。本文档不涉及与人员保护无关的ESPE功能（例如利用感应单元数据进行导航）的要求。本文档不涉及电磁兼容（EMC）发射要求。 [外文原描述]： IEC 61496-1:2020 specifies general requirements for the design, construction and testing of non-contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or part of a person as part of a safety-related system. Special attention is directed to functional and design requirements that ensure an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given in Annex A. This document is intended to be used with a subsequent part of IEC 61496 that provides particular requirements based on the sensing technology. Where a part covering the sensing technology does not exist, IEC TS 62998-1 is used. Where the IEC 61496 series does not contain all necessary provisions, IEC TS 62998-1 is used. It is an additional possibility to combine those aspects covered by the IEC 61496 series in addition to IEC TS 62998-1. This document does not specify the dimensions or configuration of the detection zone and its disposition in relation to hazards in 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. While a data interface can be used to control optional safety-related ESPE functions (Annex A), this document does not provide specific requirements. Requirements for these safety-related functions can be determined by consulting other standards (for example, IEC 61508 (all parts), IEC TS 62046, IEC 62061, and ISO 13849-1). This document can be relevant to applications other than those for the protection of persons, for example for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that have to be recognized by the sensing function have different properties from those of persons. This document does not deal with requirements for ESPE functions not related to the protection of persons (e.g. using sensing unit data for navigation). This document does not deal with electromagnetic compatibility (EMC) emission requirements. IEC 61496-1:2020 cancels and replaces the third edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) It has been clarified that some requirements for ESPEs that are dependent on sensing technology are not included in IEC 61496-1. They are provided in a subsequent part of IEC 61496. b) Requirements for protection against environmental influences from subsequent parts of IEC 61496 that are common to all ESPEs have been consolidated into IEC 61496-1. c) Some test procedures in IEC 61496-1 were incomplete. They have been expanded with more detail and step by step procedures. d) Some requirements and procedures in IEC 61496-1 are now covered by new generic machine safety standards. The requirements in IEC 61496-1 have been harmonized with references to the new generic standards.
