This practice establishes the apparatuses and materials needed, possible hazards, and two standard procedures for taking samples of cryogenic aerospace fluids for analysis. For the Dewar flask procedure, a clean Dewar flask is used to collect a sample of cryogenic aerospace fluid either from a sampling valve, or poured from a Dewar flask used for storage. Whereas, for the cryogenic sampler procedure, the sampler is used to withdraw a small amount of liquefied gas from a large supply, and is then allowed to cool until a steady stream of cryogenic liquid exists in the sampler. Once the sampling valves are closed, the trapped liquid will convert to gas and pressurize the sampling vessel.

1.1 This practice describes procedures for taking a sample of cryogenic aerospace fluid for analysis.

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 requirements prior to use. For hazard statement, see Section 5.
