ASTM F359-82(1994)e1

1.1 This practice covers the evaluation of the compatibility of nitrogen tetroxide (N 2 O 4 ) rocket engine propellant with materials which will be used in aerospace systems. The practice includes immersion procedures in the vapor phase, liquid phase, critical vapor, and vapor-liquid interface for metals, elastomers, plastics, lubricants, and other materials as applicable.

1.2 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
