BS EN 9278:2018 pdf download.Aerospace series – General Principles of Obsolescence Management of chemicals, materials and processes
1 Scope
Obsolescence is a significant risk factor for an organisation and/or a programme activity regarding the continuity of productions, services and maintenance in operational conditions of equipments and systems. It can appear in any phase of the product life cycle. Thus it is essential that the organisation determines the best strategy to be implemented in order to control these risks, implying its customers and suppliers in the definition of this strategy.
This recommendation is a document meant to be used as guidelines, for an organisation and/or a given programme, for the implementation of a coordinated management process of obsolescence risks related to chemical products and to their effects on products, especially on materials, processes and mechanical
parts.
Can be subject to obsolescences:
一all categories of equipments as well as their components;
一materials and processes used to produce, operate or maintain a product;
一all that can be bought, manufactured, repaired, be it done internally or externally;
一means of production, test and maintain.
This document excludes obsolescences related to electronic components and softwares (for more information on that subject, see EN 62402).
4 Objectives of the obsolescence management process
The aim of this process is to ensure that the product, subject of the programme, can be manufactured and supported throughout its life cycle (maintenance, spares, reparations, etc.). It enables to anticipates obsolescences and minimise their impact and their cost on the products of the organisation (actual and in the near future). The process consists in scheduled and coordinated actions intended to ensure the availability of a product during its operating life， through technically and economically practicable means of replacement. The process shall include the strategic vision of the operators of the supply chain (this vision can differ from an operator to another), the organisation-supplier balance of power (suppliers’ certification) as well as global environment (media pressure, brand image). All the actors of the supply chain are responsible for obsolescence management throughout the life cycle of a finished product with regards to customers or users. In particular, a purchaser shall state to his suppliers the requirements to which he shall himself comply. However, beyond these considerations, the key of obsolescence management is the circulation of information so that information received by any operator of the organisation, programme or supply chain can be reported, centralised in one unique focal point, and then treated, analysed, made used of and finally passed on at programme or service levels. The aim of this process is to give priority as far as possible to proactive treatment above reactive treatment (endured).
