ASTM D1837 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 LPG weathering tester 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 LP-gas, and pentane and heavier components in propane-butane and butane type fuels. The presence of hydrocarbon compounds less volatile than those of which the LP-gas is primarily composed is indicated by an increase in the 95% evaporated temperature.
ASTM D2158 IP 317 RESIDUES IN LIQUEFIED PETROLEUM (LP)GASES
This LPG tester covers the determination of extraneous materials weathering above 38C (100F) that are present in liquefiedpetroleum gases. The extraneous materials will generally be dissolved in the weathering test of LPG, but may have phase-separated in some instances.
