ASTM D1837

Standard Specification for Liquefied Petroleum (LP) Gases
This specification covers liquefied petroleum gases consisting of propane, propene (propylene), butane, and mixtures of these materials. The products are intended for use as domestic, commercial and industrial heating, and engine fuels. Care must be taken to in sampling of the liquefied gases for test results to be significant. All four types of liquefied petroleum gases covered by this specification should conform to the specified requirements for vapor pressure, volatile residue, residue matter, relative density, and corrosion.
This specification covers those products commonly referred to as liquefied petroleum gases, consisting of propane, propene (propylene), butane, and mixtures of these materials. Four basic types of liquefied petroleum gases are provided to cover the common use applications.

ASTM D2158

Standard Test Method for Residues in Liquefied Petroleum (LP) Gases
Control over the residue content (required by Specification D1835) is of considerable importance in end-use applications of LPG. In liquid feed systems, residues can lead to troublesome deposits and, in vapor withdrawal systems, residues that are carried over can foul regulating equipment. Residues that remain in vapor-withdrawal systems will accumulate, can be corrosive, and will contaminate subsequent product. Water, particularly if alkaline, can cause failure of regulating equipment and corrosion of metals.
