Ces niveaux peuvent inclure les véhicules spatiaux automatisés ou à pilotage manuel, les lanceurs, les satellites, les charges utiles, les expérimentations, les équipements sol de tests électriques et mécaniques et les organisations correspondantes.
La présente Norme peut être adaptée aux caractéristiques et contraintes spécifiques d'un projet spatial, conformément à l'ECSS-S-ST-00.

Zagotavljanje varnih proizvodov v vesoljski tehniki - Materiali, mehanski deli in procesi

Namen tega standarda je opredelitev zahtev in izjav, ki se uporabljajo za materiale, mehanske dele in postopke, za izpolnjevanje zahtev glede ciljev misije.  Ta standard opredeljuje tudi ustrezne zahteve glede dokumentacije in postopke za pridobivanje odobritve za uporabo materialov, mehanskih delov in postopkov pri izdelavi vesoljskih sistemov in z njimi povezane opreme.  Ta standard obravnava naslednje elemente: • upravljanje, vključno z organizacijo, pregledi, stanjem odobritve in nadzorom dokumentacije; • izbirne kriterije in pravila; • ocenjevanje, potrjevanje in kvalifikacijo oziroma preverjanje; • zagotavljanje kontrole in vhodna kontrola; • kriterije uporabe in pravila. Razmerje med dejavnostmi in fazami programa je opredeljeno v dodatku E.
Določbe tega standarda se uporabljajo za vse izvajalce, vključene na vseh ravneh proizvodnje vesoljskih sistemov. Ti lahko zajemajo vesoljska plovila s posadko ali brez nje, lansirnike, satelite, tovore, poskuse, električno podporno opremo na tleh, mehansko podporno opremo na tleh in njihove ustrezne ureditve. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

European foreword

This document (EN 16602-70:2016) has been prepared by Technical Committee CEN-CENELEC/TC 5

“Space”, the secretariat of which is held by DIN.
This European Standard (EN 16602-70:2016) originates from ECSS-Q-ST-70C Rev.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 April 2017, and conflicting national standards shall be

withdrawn at the latest by April 2017.

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 13291-3:2003.
The main changes with respect to EN 13291-3:2003 are listed below:
- new EN number and modified title,

- Reorganization of the content of the document to separate descriptive text and requirements,

including clarification, modification of requirements and implementation of change requests,

- Alignment of the three Standards EN 16603-32-08 (based on ECSS-E-ST-32-08C Rev.1),

EN 16602-70 (based on ECSS-Q-ST-70C Rev.1) and EN 16602-70-71 (based on ECSS-Q-ST-70-

71C),

- Additon of Subclauses 5.1.18 "Bacterial and fungus growth", 5.1.19 "Hydrogen embrittlement"

and 5.1.20 "Manned environment" coming from ECSS-Q-ST-70-71A Rev.1.

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 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, Slovakia, Slovenia, Spain,

Sweden, Switzerland, Turkey and the United Kingdom.

European Foreword

This document (FprEN 16602-70:2016) has been prepared by Technical Committee CEN/CLC/TC 5

“Space”, the secretariat of which is held by DIN (Germany).
This document (FprEN 16602-70:2016) originates from ECSS-Q-ST-70C Rev.1.
This document is currently submitted to the Unique Acceptance Procedure.
This document will supersede EN 13291-3:2003.

This document has been developed to cover specifically space systems and will the­ refore have

precedence over any EN covering the same scope but with a wider do­ main of applicability (e.g. :

aerospace).

Scope
This Standard specifies the requirements and statements applicable to
materials, mechanical parts and processes to satisfy the mission performance
requirements.
This Standard also specifies the documentation requirements and the
procedures relevant to obtaining approval for the use of materials, mechanical
parts and processes in the fabrication of space systems and associated
equipment.
This Standard covers the following:
• management, including organization, reviews, acceptance status and
documentation control;
• selection criteria and rules;
• evaluation, validation and qualification, or verification testing;
• procurement and receiving inspection;
• utilization criteria and rules.
The relationship between activities and programme phases is defined in Annex E.

The provisions of this Standard apply to all actors involved at all levels in the

production of space systems. These can include manned and unmanned
spacecraft, launchers, satellites, payloads, experiments, electrical ground
support equipment, mechanical ground support equipment, and their
corresponding organizations.

This standard may be tailored for the specific characteristics and constraints of a

space project in conformance with ECSS-S-ST-00.
