Evaluation of Materials for Manned Vessels to Assure Habitable Atmospheres.

摘要

Materials used for construction, upkeep,and routine operations of submersibles,undersea chambers,and diving complexes must be considered in view of their potential to pollute the atmosphere. Two preliminary tests,Flammability and Outgas,are used to initially screen materials. More extensive testing of materials is accomplished with a thermal gravimetric apparatus used in conjunction with gas chromatography and mass spectrometry to measure the chemicals given off by a material under thermal stress from 70to 400C.
