|Publication Date:||10 April 2002|
|ICS Code (Gaseous fuels):||75.160.30|
1.1 This practice covers, by compositional analysis, the approximate determination of the following physical characteristics of commercial propane and special-duty propane (covered by Specification D 1835): vapor pressure, relative density, and motor octane number (MON).
1.2 This practice is not applicable to any product exceeding specifications for nonvolatile residues. (See Test Method D 2158.)
1.3 For calculating motor octane number, this practice is applicable only to mixtures containing 20 % or less of propene.
1.4 For calculated motor octane number in method, this practice is based on mixtures containing only components shown in .
1.5 The values stated in SI units are to be regarded as the standard.
