F07.90 - Executive

SCOPE
1.1 These definitions cover the flow properties of gelled propellants of interest to the aerospace industry.

SCOPE
1.1 This test method covers the determination of the sensitivity of liquid monopropellants to the impact of a drop weight.
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.

SCOPE
1.1 This test method covers the evaluation of two properties of a high-energy liquid propellant. In one form, the critical internal diameter is determined in a given type of metal or plastic tubing below which propagation of stable high-velocity detonation will not take place. In the alternative form, which uses more material, detonation rate is concurrently measured. The composite donor of either size may be used in most instances to initiate detonation in experimental trap designs.
1.2 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.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

SCOPE
1.1 This test method covers the measurement of solid propellant specific impulse values.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

SCOPE
1.1 These definitions cover the flow properties of gelled propellants of interest to the aerospace industry.

SCOPE
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.

SCOPE
1.1 This test method covers the determination of the relative reactivity of materials with liquid oxygen under impact using the AFAPL impact tester. It is designed to yield an evaluation of the potential fire or explosive hazard of the material in contact with liquid oxygen under impact energy only, and shall not be used to predict such hazard from other forms of energy.
1.2 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.

SCOPE
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.

SCOPE
1.1 This test method  covers the determination of the minimum pressure at which a monopropellant ignites in the vapor phase.

SCOPE
1.1 This practice covers the threshold procedure for impact testing in high-energy propellants, and differs from Test Method D2512 only in the additional safeguards and restraints required when handling these dangerous materials, both for safety and for prevention of interfering reactions.
