Title (German)

Raumfahrtproduktsicherung - Thermo-Vakuum-Ausgasungstest für die Auswahl von Raumfahrtmaterialien; Englische Fassung EN 16602-70-02:2014


The kinetics of an outgassing process is influenced by vacuum and temperature conditions. The method described in this standard gives reliable data for material screening use exclusively. The nominal temperature for the screening test, as described in this standard is 125 °C. Results from the nominal screening test can be used for the screening of materials that have an operational temperature below 50 °C, especially if they are exposed for an extended period of time (in the order of weeks and above). This standard describes a thermal vacuum test to determine the outgassing screening properties of materials proposed for use in the fabrication of spacecraft and associated equipment, for vacuum facilities used for flight hardware tests and for certain launcher hardware. This standard covers the following: critical design parameters of the test system; critical test parameters such as temperature, time, pressure; material sample preparation; conditioning parameters for samples and collector plates; presentation of the test data; acceptance criteria; certification of test systems and their operators by audits and round robin tests. The test described in this standard is applicable for all unmanned spacecraft, launchers, payloads, experiments. The test is also valid for external hardware of inhabited space systems and for hardware to be used in terrestrial vacuum test facilities. The outgassing and condensation acceptance criteria for a material depend upon the application and location of the material and can be more severe than the standard requirements as given in This standard may be tailored for the specific characteristics and constrains of a space project in conformance with ECSS-S-ST-00. This document (EN 16602-70-02:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document will supersede DIN EN 14091:2003-06. This document has been developed to cover specifically space systems and has therefore precedence over any European Standard covering the same scope but with a wider domain of applicability (for example: aerospace).
