GB/T 28876.2-2014Flammability of materials in space experimental facilities—Part 2: Test methods (English PDF)

1 Scope

This section GB/T 28876 specifies the equipment Spacecraft aerobic environment laboratory equipment to test the use of combustible materials

And sample requirements, the upward propagation of flame test, flammability test wire insulation material, the material upward flammability test in the gaseous oxygen, heat and

Visible smoke release rate test, flammability test configuration, the flammable limit test, test temperature spontaneous combustion, heat of combustion test, and the oxygen index test

Methods fire mechanism test, flammability test evaluation criteria and the contents of the report.

This section applies to flammability testing and evaluation Spacecraft aerobic environment laboratory equipment materials used. Spacecraft, related to

Surface support equipment and special test equipment using combustible materials can be tested and evaluated with reference to use.
