Seventy-two candidate space cabin materials were tested to determine weight-loss characteristics and to identify their gas-off products. The materials were screened initially, using thermogravimetric techniques for measuring weight loss at moderate temperatures ambient to 68C for 24 hours in 5 psia nitrogen, to select those candidate materials that lose from 0.001 to 1. 0 of their weight, excluding water. The gaseous contaminants evolved from the test materials were identified by combinations of gas chromatography and mass spectrometry. An additional study was made to determine the decomposition temperatures and products of degradation for carboxynitroso rubber.
