Standard Test Methods for Volumetric Measurement of Gaseous Fuel Samples (Withdrawn 2017)

SIGNIFICANCE AND USE
The knowledge of the volume of samples used in a test is necessary for meaningful results. Validity of the volume measurement equipment and procedures must be assured for accurate results.
SCOPE
1.1 These test methods cover the volumetric measuring of gaseous fuel samples, including liquefied petroleum gases, in the gaseous state at normal temperatures and pressures. The apparatus selected covers a sufficient variety of types so that one or more of the methods prescribed may be used for laboratory, control, reference, or in fact any purpose where it is desired to know the quantity of gaseous fuel or fuel samples under consideration. The various types of apparatus are listed in Table 1.
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.
WITHDRAWN RATIONALE
Formerly under the jurisdiction of Committee D03 on Gaseous Fuels, this test method was withdrawn in January 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

7.1 Thestockcapacitiesofcalibratedgasometers(gasmeter
provers) are 2, 5, and 10 ft . The temperature and pressure at
which they can be operated must be close to the ambient
temperature and within a few inches of water column of
atmospheric pressure.The equivalent rates of flow that may be
attained, conveniently, are as follows:

NOTE 2—Gasometers having volumetric capacities up to several thou-
sand cubic feet have been made for special purposes. Their use is limited
to temperatures close to the ambient temperature, although some may be
operated as pressures slightly higher than mentioned above. These large
gasometers can hardly be classed as equipment for measuring gaseous
samples, and are mentioned only for the sake of completeness.
