41、02-70-45:2015-05 EN 16602-70-45:2014 (E) 6 1 Scope 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, fati

42、gue 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.

43、This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
