IEC 62309-2004 pdf – Dependability of products containing reused parts – Requirements for functionality and tests.
1 Scope 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. NOTE This standard can also be applied in producing product specific standards by technical committees responsible for an application sector. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050(191):1990, International Electrotechnical Vocabulary (IEV) – Chapter 191: Depend- ability and quality of service 3 Terms and definitions For the purposes of this document, the following terms and definitions apply, some of which are taken from IEC 60050-191. Figure A.3 shows the relationship between the lifetimes defined below. Lifetimes can be measured in operating time-scale or in operating time per calendar time-scale (e.g. cycles per year). 3.1 process set of interrelated or interacting activities which transforms inputs into outputs NOTE 1 Inputs to a process are generally outputs of other processes.
3.2 product result of a process [ISO 9000:2000, 3.4.2] NOTE In this standard the term “product” covers hardware (e.g. engine, mechanical part) and processed materials (e.g. lubricant). 3.3 new product product as a whole, including all of its constituent parts, that has not yet been put into normal use NOTE A new product may contain one or more “qualified-as-good-as-new” parts. 3.4 qualified-as-good-as-new quagan state of a part, which has been put into normal use on one or more occasions but differs from a second-hand part in that it is not just a re-sale, but it is also reconditioned and subjected to fully defined and documented quality checks prior to re-sale, such that it is in all dependability issues as good as new for the as-new designed life of the product (ANDL) NOTE Qualified-as-good-as-new parts have been qualified as fit for purpose and as dependable as new parts for the as-new designed life (ANDL) of a product. The necessary level of documentation and quality checks depends on the application and the market requirements. 3.5 useful life under given conditions, time interval beginning at a given instant of time, and ending when the failure intensity becomes unacceptable or when the item is considered un-repairable as a result of a fault [IEV 191-10-06] NOTE Equipment may have a useful life of 40 years with certain components changed periodically, thus the useful life of the equipment would be 40 years. 3.6 new designed life NDL intended life of a product containing only new parts for the first use within a specific set of operating conditions NOTE The “new designed life” may depend on the usage of the product, market requirements, efficiency, economy, technology, etc. 3.7 as-new designed life ANDL intended life of a product containing at least one reused part for use within a specific set of operating conditions NOTE The NDL and the ANDL need not be of equal length nor be in any set ratio but it is desirable that the ANDL should not be less than the NDL.
