产品加速测试方法

[中文适用范围]： 本文件提供了各种加速测试技术在测量或改进项目可靠性方面的应用指南。识别项目使用中可能遇到的潜在故障模式及其缓解措施对于确保项目的可靠性至关重要。这些方法的目的是在压缩或加速的时间内识别潜在的设计弱点，提供关于项目可靠性的信息，或实现必要的可靠性和可用性改进。本文件涉及不可修复和可修复系统的加速测试。它可用于概率比序贯测试、固定持续时间测试和可靠性改进/增长测试，其中可靠性的测量可能与标准故障发生概率不同。本文件还扩展到当前的加速测试或生产筛选方法，这些方法可以识别由制造错误引入项目的弱点，这可能影响项目可靠性。然而，本文件不包括服务和人员。 [外文原描述]： IEC 62506:2023 provides guidance on the application of various accelerated test techniques for measurement or improvement of item reliability. Identification of potential failure modes that can be experienced in the use of an item and their mitigation is instrumental to ensure dependability of an item. The object of the methods is to either identify potential design weakness or provide information on item reliability, or to achieve necessary reliability and availability improvement, all within a compressed or accelerated period of time. This document addresses accelerated testing of non-repairable and repairable systems. It can be used for probability ratio sequential tests, fixed duration tests and reliability improvement/growth tests, where the measure of reliability can differ from the standard probability of failure occurrence. This document also extends to present accelerated testing or production screening methods that would identify weakness introduced into the item by manufacturing error, which can compromise item reliability. Services and people are however not covered by this document.
