ASTM F309-04(2018)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F309 − 04 (Reapproved 2010) F309 − 04 (Reapproved 2018)
Standard Practice for
Liquid Sampling of Noncryogenic Aerospace Propellants
This standard is issued under the fixed designation F309; the number immediately following the designation indicates the year of original
adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript
epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice covers procedures for obtaining a sample of noncryogenic aerospace propellant. Two procedures are covered
as follows:
Procedure 1—1Closed—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 appropriate safety safety, health, and healthenvironmental practices and determine the
applicability of regulatory limitations prior to use. For hazard statements see Sections 4 and 5.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
2. Referenced Documents
2.1 ASTM Standards:
F311 Practice for Processing Aerospace Liquid Samples for Particulate Contamination Analysis Using Membrane Filters
3. Summary of Practice
3.1 Samples are withdrawn from the system by (1) a closed vessel capture, and (2) an open-end vessel (see Fig. 1). Both
procedures are practical for most liquid aerospace propellants not excessively corrosive or toxic.
4. Apparatus
4.1 Stainless Steel Pressure Sampling Cylinders, 1-L capacity, equipped with stainless steel valves on each end.
4.1.1 Caution—Pressure sampling cylinders must be marked for the liquid being sampled. Cylinders for one material must not
be interchanged with sampling cylinders of other materials because of the possibility of incompatibility.
4.2 Full Protective Suits.
4.2.1 Caution—Due to the toxic and corrosive nature of most propellent fluids and their vapors, extreme care must be exercised
in handling. Full protective suits must be worn when sampling these fluids.
4.3 Polyethylene Wash Bottle, 1-L capacity, filled with demineralized water, filtered in the manner described in Practice F311.
4.4 Stainless Steel Bucket.
4.5 Miscellaneous Fittings, as needed for sample point adaption.
5. Hazards
5.1 Care should be taken when handling propellants since most of them are toxic to some degree. Care should also be taken
when sampling fluids from a system under dynamic conditions.
This practice is under the jurisdiction of ASTM Committee E21 on Space Simulation and Applications of Space Technology and is the direct responsibility of
Subcommittee E21.05 on Contamination.
