ASTM D – 11 Standard Test Method for Volatility of Liquefied Petroleum (LP) Gases
This test method is a measure of the relative purity of the various types of liquefied petroleum LP gases and helps to ensure suitable volatility performance.
The test results, when properly related to vapor pressure and density of the product, can be used to indicate the presence of butane and heavier components in propane-type 1d837, and pentane and heavier components in propane-butane and butane-type fuels.
Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in October because the method is no longer being maintained and updated by a subcommittee. The following language was added editorially to the withdrawn statement in May This standard is withdrawn with no replacement.
D still references the use of mercury thermometers. Replacement of the armored mercury thermometer currently specified in D is not a simple replacement by a non-mercury liquid-in-glass thermometer or a digital contact thermometer.

Some initial test work showed serious discrepancies in temperature measurements, thus a significant work program would have to be carried out to validate a replacement, non-mercury thermometer. D was originally published in as a rudimentary means of limiting heavier components in LPG products.
Gas chromatography was in the early stages of development at that time, and was not available for routine commercial use.
Current gas chromatographic methods are far more accurate and precise in identifying and measuring heavy components in LPG products, and are the preferred analytical method to accurately determine the composition or presence of heavy components in LPG. There is no research report or other documentation showing that the current limits in D correlate with the quantified compositional limits specified in D, the specification for LPGs. Therefore Test Method D has been withdrawn.
ASTM D – 01 Standard Test Method for Volatility of Liquefied Petroleum (LP) Gases
A withdrawn ASTM test method is still available for use, and the last published issue D will continue to be available from ASTM International as an historical document after it is withdrawn.
The significance of withdrawing a standard is to identify that the method is no longer being maintained and updated by a subcommittee. Mercury, or its vapor, may be hazardous to d187 and corrosive to materials. Caution should be taken when handling mercury and mercury containing products.
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.
