18、e fields, the component life time compared to the lengthy life cycle of finished products and the arrival of new regulations drive organisations into structuring obsolescence management. This need has become important in these fields as a result of: the effort necessary for the qualification of mate
19、rials and processes (due to a high level of performance and security requirements, to the complexity of interactions between systems, to the large number of industrial actors, to the multinational nature of programmes, etc.), the regulation requirement of conformity from the produced configuration t
20、o the qualified configuration (for example of certification by an official organization). These characteristics reinforce three aerospace industry priorities: Traceability, Stability of technical choices, Anticipation of evolutions. New regulations such as RoHS or REACH, creating potential obsolesce
21、nces (related to authorization and substance use restriction processes), force to take this obsolescence risk into account. They created increasingly stronger concerns for organisations willing to express a need of information from the aerospace industry information within themselves, and within eac
22、h of their programmes and with respect to their suppliers regarding necessary and accessible data that shall be supplied, shared and tracked. For example, information exchange principles are given in Annex A. Obsolescence risk is meant as a potential or proven event, resulting from the non-availabil
23、ity of a product. The submentioned differentiation will be observed in obsolescence cases: Potential: obsolescence is predicted without a known deadline Proven: obsolescence is indicated with a known deadline Endured: obsolescence was unexpected, it is assessed. Obsolescences of chemicals and their
24、effects on products, especially materials, processes and mechanical part are tackled in this General Recommendation, developed within the “Programme Management” working group to which representatives of aerospace and armament industries participated. The obsolescences related to chemicals originate
25、in: New regulations or evolution of existing laws (environment, health, safety, etc.), Evolution for suppliers: changes of reference, evolutions of products, manufacturing processes, formulation, rationalising of product ranges, manufacturing halts, etc., Supplier failure: bankruptcies, evolution of
26、 industrial organisation, industrial accidents (fire, flooding, etc.), Import export obligations (ITAR, export controls, export licence, etc.), Market laws or industrial rules (volume of production too low, ageing technology, etc.), Etc. prEN 9278:2017 (E) 5 1 Scope Obsolescence is a significant ris
27、k 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 strateg
28、y 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
29、obsolescence risks related to chemical products and to their effects on products, especially on materials, processes and mechanical parts. Can be subject to obsolescences: all categories of equipments as well as their components, materials and processes used to produce, operate or maintain a product
30、, all that can be bought, manufactured, repaired, be it done internally or externally, 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). 2 Normative references Not applicabl

Note 1 to entry: Such a product is qualified as obsolete Note 2 to entry: An obsolescence can have different origins: regulations, technical evolution, suppliers failure, industrial evolution
32、s, etc. Note 3 to entry: The supplying impossibility can be permanent, temporary or potential. 3.2 programme coordinated set of technical, administrative and financial tasks, intended to design, develop, produce and use a product, satisfying a need under the best economic conditions, as well as ensu

38、aces, its main functions and requirements, etc. It must not be confused with the point of use which is the location of use of a component in a product. 3.10 substance chemical element and its compounds in the natural state or obtained by any manufacturing process SOURCE: according to Reach Guide GIF
39、AS prEN 9278:2017 (E) 7 3.11 life cycle this describes the whole series of developments of the product throughout its life starting from the expression of its need until the disposal, whatever the form is Note 1 to entry: The life cycle includes the following phases: Initial statement of requirement
40、, Feasibility, Definition, Development, Production, Use, Withdrawal. SOURCE: according to EN 9200 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 (maintena
41、nce, 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
42、 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 we
43、ll 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
44、 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, a
45、nalysed, 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). Detectability is especially important and belongs to the organisation and the programme. In the aerosp
46、ace field, action plans to be implemented in order to resolve obsolescences are often long and costly. Thus, an obsolescence detected early enough allows an easier implementation while ensuring a safety margin. Furthermore, the sooner the impacts are identified, the sooner it is possible to make sur
47、e that all applications are taken care of, and, in this way, to avoid “bad surprises” when the time comes to implement the replacement solution or to stop the current solution. Obsolescence risk management is part of a process that is similar to risk management as described in the EN 9239, given in
48、the following Figure as a reminder. prEN 9278:2017 (E) 8 Stage 1 Setting up the framework of risk management Stage 2 Identifying Stage 3 Assessing Stage 4 Treating Stage 6 Capitalising MonitoringandControllingStage5CommunicatingStage7Figure 1 Main stages of risk management This process relates both
49、to the organisation (then including, for example, all obsolete products at the same time) and the programmes (affected by their own obsolescences). One of the issues is optimising the structure between actions carried on by the organisation and those dealt with by each programme. Another issue is to share the efforts between various programmes within one organisation, or even between several organisations. The organisation is the owner of the Obsolescence Management Process, and the programme is in c
