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.
