标准摘要
[中文适用范围]: 本国际标准规定了测试观察值是否符合以下条件的程序: - 故障率; ——失效强度; - 平均无故障时间; ——平均故障间隔时间;符合给定的要求。假设(除非另有说明)在观察期间(累计相关测试时间),故障的时间间隔或故障之间的时间间隔是独立的,并且呈相同的指数分布。注:该假设意味着故障率或故障强度是恒定的。规定了三种类型的测试计划如下: ——顺序测试计划; - 时间/故障终止测试计划,包括固定时间/故障终止测试计划和可设计以满足特定需求的替代时间/故障终止测试计划; - 固定日历时间/失败终止测试计划。 IEC 60605-1 的 7.3 中给出了测试计划选择的一般指南。 [外文原描述]: Specifies procedures to test whether an observed value of: - failure rate; - failure intensity; - mean time to failure; - mean operating time between failures; complies with a given requirement. Three types of test plans are prescribed as follows: - sequential test plans; - time/failure terminated test plan; - fixed calendar time/failure terminated test plans. Cancels and replaces IEC 60605-7, published in 1978, and its amendment 1 (1990), of which its constitutes a technical revision.
英文名称Reliability testing - Compliance tests for constant failure rate and constant failure intensity
