ASTM F309-04

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 1-- Closed System (Section 6), and
Procedure 2--Open-End Procedure (Section 7).
1.2  This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
