Electromechanical elementary relays - Part 2-1: Reliability - Procedure for the verification of B＜sub＞10＜/sub＞ values 机电基本继电器.第2-1部分:可靠性.B＜sub＞10＜/sub＞值的验证程序

发布日期： 2017-05-30

当可靠性验证的增强要求适用时，IEC 61810-2-1:20 17规定了机电初级继电器的可靠性测试程序。
根据IEC 62061和ISO 13849-1，对机械安全相关控制系统中的继电器给出了特殊规定。对于此类继电器，危险故障的B10值（B10D值）源自本文件规定的试验。
与上一版相比，此版本包括以下重大技术变更:
-在第5条中将试验限制为10米循环；
-在特定情况下，将所需测试样本数目减少至5个；
-根据条款4引入WeiBayes分析用于常规测试。

IEC 61810-2-1:2017 specifies reliability test procedures for electromechanical elementary relays when enhanced requirements for the verification of reliability apply.

Particular provisions are given for relays incorporated in safety-related control systems of machinery in accordance with IEC 62061 and ISO 13849-1. For such relays, B10 values for dangerous failures (B10D values) are derived from the tests specified in this document.

This edition includes the following significant technical changes with respect to the previous edition:

- limitation of tests to 10 M cycles in Clause 5;

- reduction of required number of test samples to 5 in specified cases;

- introduction of WeiBayes analysis for routine test under Clause 4.
