Space systems. Safety and compatibility of materials. Method to determine the flammability thresholds of materials1 Scope This Technical Specification provides a method to determine the oxygen concentration threshold when a material exposed to a standard ignition source self extinguishes at a given constant total pressure, temperature, convective flow, and gravity level conditions. The method can also be used to determine other flammability limits, such as the total pressure or forced convective velocity thresholds, while maintaining other test conditions
