(Practice)Standard Practice for Liquid Sampling of Noncryogenic Aerospace Propellants
Standard Practice for Liquid Sampling of Noncryogenic Aerospace Propellants
ABSTRACT
This practice covers procedures for obtaining a sample of noncryogenic aerospace propellant. Two procedures are covered as follows: procedure 1 (closed system) and procedure 2 (open-end procedure).
SCOPE
1.1 This practice covers procedures for obtaining a sample of noncryogenic aerospace propellant. Two procedures are covered as follows:
Procedure 1Closed System (Section 6), and
Procedure 2Open-End Procedure (Section 7).
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. For hazard statements see Sections 4 and 5.
