介绍了检查重复使用零件的可靠性和功能性以及它们在新产品中的使用情况的概念。还提供了关于含有此类重复使用零件的产品所需的测试/分析的信息和标准，这些零件在产品的设计寿命内被宣布为“与新零件一样合格”。 本标准的目的是通过测试和分析，确保包含重复使用零件的新产品的可靠性和功能性与仅包含新零件的产品相当。

Introduces the concept to check the reliability and functionality of reused parts and their usage within new products. Also provides information and criteria about the tests/analysis required for products containing such reused parts, which are declared "qualified-as-good-as-new" relative to the designed life of the product. The purpose of this standard is to ensure by tests and analysis that the reliability and functionality of a new product containing reused parts is comparable to a product with only new parts.
