Abstract:

Ninety-eight candidate materials for space cabin construction were tested to establish possible volatile gas-off and oxidation products. Test conditions were designed to simulate the normal space cabin environment. After pretreatment at 0.1 torr and at 25C, candidate materials were stored in bench-scale simulators for 14 days at 68C, and for 30, 60, and 90 days at 25C, in a 5 psia oxygen atmosphere with 20-40 relative humidity. Individual components of the volatile contaminants were identified and the quantities evolved were estimated by gas chromatographic and mass spectrometric analyses. In addition to the gas-off experiments, a cryogenic system for serial trapping of atmospheric contaminants was constructed. Gas chromatographic and mass spectrometric analyses were performed on four samples of atmospheres from bio-environmental systems. Author
