标准摘要
[中文适用范围]: 本文档提供了许多优化的测试计划、相应的边界线和特性。此外,还给出了使用电子表格程序设计测试计划的算法,以及如何选择测试计划的指导。 本文档规定了测试观察值是否符合给定要求的程序,包括: - 故障率 - 故障强度 - 平均运行时间到故障(MTTF) - 平均运行时间间隔故障(MTBF) 假设在累积测试时间内,故障时间或故障间隔时间是独立且同指数分布的。这个假设意味着故障率或故障强度被假定为常数。 描述了四种测试计划类型: - 截断序贯概率比测试(SPRT) - 固定时间/故障终止测试(FTFT) - 无替换的固定日历时间终止测试 - 组合测试 本文档不涵盖如何计划、执行、分析和报告测试的指导。这些信息可以在IEC 60300-3-5中找到。 本文档不描述测试条件。这些信息可以在IEC 60605-2和IEC 60300-3-5中找到。 [外文原描述]: IEC 61124:2023 gives a number of optimized test plans, the corresponding border lines and characteristics. In addition, the algorithms for designing test plans using a spreadsheet program are also given, together with guidance on how to choose test plans. This document specifies procedures to test whether an observed value of failure rate, failure intensity, mean operating time to failure (MTTF), mean operating time between failures (MTBF), conforms to a given requirement. It is assumed, except where otherwise stated, that during the accumulated test time, the times to failure or the operating times between failures are independent and identically exponentially distributed. This assumption implies that the failure rate or failure intensity is assumed to be constant.
