This International Standard introduces the concept to check the reliability and functionality of reused parts and their usage within new products. It 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.

In this standard, the term "product" covers electrical, electro-mechanical, mechanical parts or hardware that may contain software. "Qualified-as-good-as-new" does not apply to software products, concepts and ideas.

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. This would justify the manufacturer granting the next customer the full warranty of the product with "qualified-as-good-as-new" parts.
