(Main)Space product assurance - Materials, mechanical parts and processes obsolescence management handbook
Space product assurance - Materials, mechanical parts and processes obsolescence management handbook
This Handbook provides guidelines to manage obsolescence of Materials, Mechanical Parts and Processes (in-house and sub-contracted).
It is useful for any actor of the European Space sector.
It covers Materials, Mechanical Parts and Processes (MMPP) used in flight hardware as well as ground support equipment (including test systems) and materials or tools used during process (not in the final product) and skills (knowhow).
It is not within the scope of this Handbook to address EEE components and software.
This document describes the general causes of obsolescences and introduces the concepts of proactive and reactive obsolescence management, depending of the programme phase.

European Foreword
This document (CEN/CLC/TR 17602-70-23:2021) has been prepared by Technical Committee
CEN/CLC/JTC 5 “Space”, the secretariat of which is held by DIN.
It is highlighted that this technical report does not contain any requirement but only collection of data
or descriptions and guidelines about how to organize and perform the work in support of EN 16602-
70-23.
This Technical report (CEN/CLC/TR 17602-70-23:2021) originates from ECSS-Q-HB-70-23A.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such
patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association.
This document has been developed to cover specifically space systems and has therefore precedence
over any TR covering the same scope but with a wider domain of applicability (e.g.: aerospace).
Scope
This Handbook provides guidelines to manage obsolescence of Materials, Mechanical Parts and
Processes (in-house and sub-contracted).
It is useful for any actor of the European Space sector.
It covers Materials, Mechanical Parts and Processes (MMPP) used in flight hardware as well as
ground support equipment (including test systems) and materials or tools used during process (not in
the final product) and skills (know-how).
It is not within the scope of this Handbook to address EEE components and software.
This document describes the general causes of obsolescences and introduces the concepts of proactive
and reactive obsolescence management, depending of the programme phase.

1. mechanical part
2. process
3.2 Terms specific to the present handbook
3.2.1 bill of MMPP

product
NOTE This is reported in Declared Materials List (DML), Declared Processes
List (DPL) and Declared Mechanical Parts List (DMPL).
3.2.2 criticality
measure of severity of the consequences of MMPP obsolescence with regard to its use
3.2.3 obsolescence
transition from availability to unavailability of a material, mechanical part or process from the
manufacturer or supplier
NOTE The unavailability can be permanent or temporary.
3.2.4 obsolescence management network
network of persons in charge of collecting, transmitting and recording all the information concerning
obsolescence issues and responsible to implement risk mitigation actions and obsolescence treatment
actions
NOTE Members of the obsolescence network can represent different
functions (e.g. procurement, quality, production, and design office)
3.2.5 obsolescence manager
person in charge of coordinating and supervising obsolescence management at company level and
following up obsolescence treatment projects progress
3.2.6 obsolescence risk analysis
assessment of the probability and severity of the risk of obsolescence and prioritization of the
obsolescence risk
3.2.7 proactive obsolescence management
actions to anticipate obsolescence and to mitigate the risks linked to obsolescence issues
3.2.8 reactive obsolescence management
reactive strategy consists in reacting only when the obsolescence is proven
1 Obsolescence is considered as proven when a discontinuance date is
known.
2 The discontinuance date can be transmitted through a formal
document by the supplier or related to date of ban determined by a
regulation.
