ASTM F309-70(2000)

Standard Practice for Liquid Sampling of Noncryogenic Aerospace Propellants

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.

1. 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 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 appro-
priate safety and health practices and determine the applica-
bility of regulatory limitations prior to use. For hazard state-
ments see Sections 4 and 5.
