ECSS-Q-70-02A – Thermal vacuum outgassing test for the screening of space materials (26 May 2000)

This standard has been cancelled and replaced by ECSS-Q-ST-70-02C (15 November 2008).

Scope

This Standard describes a thermal vacuumtest to determine the outgassing 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:

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 acceptance criteria for a material, based upon the outgassing test data, depends upon the application and location of the material and may be more severe than the standard requirements as given in subclause 7.2.
