Standard Test Method for Shock Sensitivity of Liquid Monopropellants by the Card-Gap Test

2017-08-16 /Historical
Superseeded by:

1.1 In considering the handling properties of a liquid propellant, serious consideration is given to the possibility of hazard initiated by hydrodynamic shock. The consequences of such a shock may include: (1) nonpropagating explosion, (2) propagating but low-velocity detonation, and (3) propagating high-velocity detonation. All three are hazards; the test described herein is useful for one hazard only, namely propagating high-velocity detonation.

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.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
