Space product assurance - Mechanical testing of metallic materials

This Standard specifies requirements for mechanical testing of metallic materials to be used in the fabrication of spacecraft hardware.
This Standard establishes the requirements for most relevant test methods carried out to assess the tensile, fatigue and fracture
properties of metallic materials. It does not give a complete review of all the existing test methods for the evaluation of mechanical
properties of metallic materials.
Furthermore, this Standard specifies requirements for the evaluation, presentation and reporting of test results.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.

Zagotavljanje varnih proizvodov v vesoljski tehniki - Mehansko preskušanje kovinskih materialov

Ta standard določa zahteve za mehansko preskušanje kovinskih materialov, ki se uporabljajo pri izdelovanju vesoljske strojne opreme.  Ta standard določa zahteve za najustreznejše preskusne metode, ki se izvajajo za oceno nateznih lastnosti, lastnosti utrujenosti in pokanja kovinskih materialov. Ne podaja popolnega pregleda vseh obstoječih preskusnih metod za oceno mehanskih lastnosti kovinskih materialov.  Poleg tega ta standard določa zahteve za oceno, predstavitev in sporočanje rezultatov preskusa. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

Foreword
This document (EN 16602-70-45:2014) has been prepared by Technical
Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN.
This standard (EN 16602-70-45:2014) originates from ECSS-Q-ST-70-45C.
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 2015,
and conflicting national standards shall be withdrawn at the latest by April
2015.
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 EN covering the same scope but with a wider
domain of applicability (e.g. : aerospace).

organizations of the following countries are bound to implement this European
Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic,
