标准范围

IEC 61810-2:20 17涵盖了使用适当的统计方法评估耐久性试验以获得继电器可靠性特性的试验条件和规定。本文件适用于被视为不可修复项目（即故障后不修复的项目）的机电初级继电器。本文件不包括适用可靠性验证增强要求的机电初级继电器的程序。与上一版相比，此版本包括以下重大技术变更:-不仅增加了图形方法，还增加了数值方法；-在特定情况下减少样本数量；-增加了新的置信区间子条款；-增加了WeiBayes方法，以更低的工作量促进合规性测试（常规测试）；-将附件重组为数据分析附件A（规范性）和附件B（资料性），其中提供了数据分析的各种实例；-原附件C已纳入经修订的附件B；-新的附件C取代旧的附件D。

 IEC 61810-2:2017 covers test conditions and provisions for the evaluation of endurance tests using appropriate statistical methods to obtain reliability characteristics for relays.
This document applies to electromechanical elementary relays considered as non-repaired items (i.e. items which are not repaired after failure).
This document does not cover procedures for electromechanical elementary relays where enhanced requirements for the verification of reliability apply.
This edition includes the following significant technical changes with respect to the previous edition:
- not only graphical but also numerical methods are added;
- reduction of number of samples in specified cases;
- new subclauses of confidence intervals are added;
- the WeiBayes approach is added to facilitate compliance tests (routine test) with lower effort;
- annexes have been restructured into an Annex A for data analysis (normative) and Annex B (informative) where various examples of the data analysis are given;
- the former Annex C has been incorporated into the modified Annex B;
- a new Annex C replaces the old Annex D.
