Abstract : Nonmetallic materials considered for application in enclosed habitable spaces are analyzed to identify thermal decomposition and gas-off products for the assessment of potential toxic hazards. A thermogravimetric analyzer-mass spectrometer system capable of establishing environments for the sample that simulate either normal usage or catastrophic situations is used for these investigations. The threshold values obtained indicate that the instrumentation described is capable of providing extremely useful data which are essential for subsequent toxicological evaluations.
