Space product assurance - Relifing procedure - EEE components

This standard specifies the requirements, also known as "relifing requirements", for the planned, intentional storage, control, and removal from storage of electronic, electrical and electromechanical parts which are intended to be used for space applications.
This standard covers the relifing of all components as defined by ECSS-Q-ST-60 and ECSS-Q-ST-60-13.
The relifing process is a lot quality control activity.  The inspections and tests defined do not constitute an up-screening or up-grading of components to a higher level of quality than procured to.
In line with ECSS-Q-ST-60, this standard differentiates between classes of components through different sets of standardization requirements.
The classes provide levels of trade-off between assurance and risk. The highest assurance and lowest risk is provided by Class 1 and the lowest assurance and highest risk by Class 3. Procurement costs are typically highest for Class 1 and lowest for Class 3. Mitigation and other engineering measures can decrease the total cost of ownership differences between the three classes. The project objectives, definition and constraints determine which class or classes of components are appropriate to be utilised within the system and subsystems.
-   Class 1 components are described in Clause 4, 5 and 6
-   Class 2 components are described in Clause 4, 5 and 6
-   Class 3 components are described in Clause 4, 5 and 7
The requirements of this document apply to all parties involved at all levels in the integration of EEE components into space segment hardware and launchers.
This standard is applicable to all EEE parts covered by ECSS-Q-ST-60 and used in space programmes.
This standard is not applicable to dice.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Raumfahrtproduktsicherung - Wiederbelebungsprozeduren für EEE-Komponenten

Assurance produit des projets spatiaux - Procédure de déstockage - Composants EEE

La présente norme définit les exigences (également désignées « exigences de remise en
état ») relatives au stockage, à la manutention et au déstockage planifiés et volontaires
des composants électroniques, électriques et électromécaniques destinés aux
applications spatiales.
La présente norme couvre la remise en état de tous les composants tels que définis par
l’ECSS-Q-ST-60 et l’ECSS-Q-ST-60-13.
Le processus de remise en état relève de la maîtrise de la qualité. Les contrôles et essais
définis ne constituent pas une valorisation ou une mise à niveau des composants à un
seuil de qualité supérieur à celui pour lequel ils ont été fournis.
Conformément à l’ECSS-Q-ST-60, la présente norme différencie les classes de
composants au moyen de différents ensembles d’exigences de normalisation.
Les classes fournissent des niveaux de comparaison entre l’assurance et le risque.
L’assurance optimale et le risque minimal sont fournis par la classe 1, tandis que
l’assurance la plus faible et le risque le plus élevé relèvent de la classe 3. Les coûts
d’approvisionnement sont en général les plus élevés pour la classe 1 et les plus bas pour
la classe 3. Des mesures d’atténuation et autres mesures techniques peuvent faire baisser
les différences de coût total de possession entre les trois classes. Les objectifs, la définition
et les contraintes du projet déterminent la ou les classes de composants appropriée(s) à
utiliser dans le système et les sous-systèmes.
· Les composants de classe 1 sont décrits dans l’Article 4, l’Article 5 et l’Article 6.
· Les composants de classe 2 sont décrits dans l’Article 4, l’Article 5 et l’Article 6.
· Les composants de classe 3 sont décrits dans l’Article 4, l’Article 5 et l’Article 7.
Les exigences du présent document s’appliquent à l’ensemble des parties impliquées à
tous les niveaux de l’intégration des composants EEE dans le matériel spatial et les
lanceurs.
La présente norme s'applique à l'ensemble des composants EEE concernés par l'ECSS-QST-
60 et utilisés dans le cadre de programmes spatiaux.
Elle ne concerne pas les microplaquettes.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d’un
projet spatial, conformément à l’ECSS-S-ST-00.

European Foreword
This document (EN 16602-60-14:2020) has been prepared by Technical Committee
CEN-CENELEC/TC 5 “Space”, the secretariat of which is held by DIN.
This document (EN 16602-60-14:2020) originates from ECSS-Q-ST-60-14C Rev.1
Corrigendum 1.

This European Standard shall be given the status of a national standard, either by

publication of an identical text or by endorsement, at the latest by March 2021,
and conflicting national standards shall be withdrawn at the latest by March
2021.
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 supersedes EN 16602-60-14:2014.
The main changes with respect to EN 16602-60-14:2014 are:
 Creation of two relifing flows: one covering Class 1 and Class 2
components and the other covering Class 3 components
 Harmonization with EN 16602-60:2015 (based on ECSS-Q-ST-60C Rev.2)
 Introduction of the applicability of the relifing requirements to commercial
components
 Change of timing requirements for relifing (from 7+3 to 7+4+4 years)
increasing the maximum elapsed time between date code and time of
mounting from 10 to 15 years
 Transformation of normative Annex A "Relifing report - DRD" by into
informative Annex C "Guidelines for a Relifing report"
 Deletion of informative Annex B "ESD".
This document has been prepared under a standardization request 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 EN covering the same scope but with a wider
domain of applicability (e.g. : aerospace).
According to the CEN-CENELEC Internal Regulations, the national standards
organizations of the following countries are bound to implement this European
Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic,
Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia,

higher level of quality than procured to.
In line with ECSS-Q-ST-60, this standard differentiates between classes of
components through different sets of standardization requirements.
The classes provide levels of trade-off between assurance and risk. The highest
assurance and lowest risk is provided by Class 1 and the lowest assurance and
highest risk by Class 3. Procurement costs are typically highest for Class 1 and
lowest for Class 3. Mitigation and other engineering measures can decrease the
total cost of ownership differences between the three classes. The project
objectives, definition and constraints determine which class or classes of
components are appropriate to be utilised within the system and subsystems.
 Class 1 components are described in Clause 4, 5 and 6
 Class 2 components are described in Clause 4, 5 and 6
 Class 3 components are described in Clause 4, 5 and 7
