标准范围

IEC 61486-1:20 20规定了非接触式电敏防护设备（ESPE）的设计、构造和测试的一般要求，该设备专门设计用于检测作为安全相关系统一部分的人员或人员的一部分。特别关注功能和设计要求，以确保实现适当的安全相关性能。ESPE可以包括可选的安全相关功能，其要求见附录A。本文档旨在与IEC 61496的后续部分一起使用，该部分提供了基于传感技术的特定要求。如果不存在涵盖传感技术的部分，则使用IEC TS 62998-1。如果IEC 61496系列不包含所有必要的规定，则使用IEC TS 62998-1。除了IEC TS 62998-1之外，还可以组合IEC 61496系列涵盖的方面。本文件没有规定检测区的尺寸或配置及其与任何特定应用中的危险相关的配置，也没有规定任何机器的危险状态。它仅限于ESPE的功能及其与机器的接口方式。虽然数据接口可用于控制可选的安全相关ESPE功能（附录A），但本文件未提供具体要求。这些安全相关功能的要求可以通过参考其他标准（例如，IEC 61508（所有部分）、IEC TS 62046、IEC 62061和ISO 13849-1）来确定。本文件可以与保护人员以外的应用相关，例如保护机器或产品免受机械损坏。在那些应用中，不同的要求可能是合适的，例如当必须由感测功能识别的材料具有与人的特性不同的特性时。本文件不涉及与人员保护无关的ESPE功能的要求（例如，使用传感单元数据进行导航）。本文件不涉及电磁兼容性（EMC）发射要求。IEC 61486-1:20 20取消并取代了2012年发布的第三版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)已经澄清，IEC 61496-1中不包括依赖于传感技术的ESPE的一些要求。它们在IEC 61496的后续部分中提供。b)所有ESPE共有的IEC 61496后续部分的环境影响防护要求已合并到IEC 61496-1中。c)IEC 61496-1中的一些测试程序不完整。它们已经被更详细和一步一步的程序扩展。d)IEC 61496-1中的一些要求和程序现已包含在新的通用机器安全标准中。IEC 61496-1中的要求已参考新的通用标准进行了协调。

IEC 61486-1:2020 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 61486-1:2020 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.
