[System of hygienic testing of non-metallic materials used to equip space craft]

In view of a wide use of polymers in the spacecraft interior and their potential hazard, a system of hygienic control over their safety at every manufacture stage has been introduced. The system includes: an analysis of a list of polymers; laboratory testing of samples under standard conditions; bench testing of various polymers used in the hardware and software under operational conditions; an examination of space cabin environments in real flights. The system of hygienic control allows selection of the safest polymers, i.e. those with minimum outgasing.
