IEC 62506:2023 CMV包含官方标准及其注释版本。注释版本为您提供了一种快速简单的方法来比较IEC 62506:2023版2.0和之前的IEC 62506:2013版1.0之间的所有更改。此外，还提供了IEC TC 56专家的意见，以解释最相关变更的原因，或澄清内容的任何部分。 IEC 62506:2023为测量或改进项目可靠性的各种加速测试技术的应用提供了指导。识别在使用物品时可能经历的潜在故障模式及其缓解有助于确保物品的可靠性。这些方法的目的是识别潜在的设计弱点或提供关于项目可靠性的信息，或者实现必要的可靠性和可用性改进，所有这些都在压缩或加速的时间段内。本文件涉及不可修复和可修复系统的加速测试。它可用于概率比顺序测试、固定持续时间测试和可靠性改进/增长测试，其中可靠性的度量可以不同于故障发生的标准概率。本文件还扩展到提出加速测试或生产筛选方法，这些方法将识别由制造错误引入项目的弱点，这些弱点可能会损害项目的可靠性。但是，本文档不包括服务和人员。

IEC 62506:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62506:2023 edition 2.0 and the previous IEC 62506:2013 edition 1.0. Furthermore, comments from IEC TC 56 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content.

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.
