AS IEC 62402:2014 pdf free.Obsolescence management – Application guide
As a general principle, the obsolescence phase of a product begins immediately after the information about discontinuance is issued and the product is considered as obsolescent, as shown in Figure 1. The information at the obsolescent phase change is often in the form of a product discontinuance notice (PDN)， end-of-life (EOL) notification or lifetime buy (LTB) notification. A product change notice (PCN) may also cause a product to enter the obsolescence phase for certain manufacturers (OCM or OEM). For a software product, the obsolescence phase commences once the original software manufacturer indicates that the software is no longer supported.
A product may be considered obsolete once it is no longer available from the original manufacturer, even thought some product is still in the supply chain.
Dependability management encompasses obsolescence management, which is the process of assuring that the product is manufacturable and supportable for the intended life,see Figure 2. The process consists of planned and co-ordinated activities for providing availability of a product during its intended life, by the economic and practicable provision of replacement components and support activities. Figure 3 shows the relationship between obsolescence management and product life cycle.
Some obsolescence-related activities may be determined by contractual, regulatory and statutory requirements. Personnel assigned to obsolescence tasks should be aware of such situations and act accordingly. Typical contractual, regulatory and statutory issues involving obsolescence are long-term delivery obligations and those given in IEC 60300-2 Subclause 5.3 and IEC/TS 62239 for electronic component management plans.
In the framework of the dependability management planning, an obsolescence management plan should be used to ensure adequate selection and timely implementation of relevant obsolescence activities.
The objective of the obsolescence management plan should be to describe strategies for identification and mitigation of the effects of obsolescence through all stages of the product life cycle. The plan can be part of another plan or a separate document.AS IEC 62402 pdf free download.
