Summary of Method
The volatility of liquefied petroleum (LP) gases is determined by allowing
a precooled sample to weather under specified conditions and observing
the temperature when 95% has evaporated. Residues in LP gases are
determined by weathering of a precooled sample and determination of the
volume remaining at 100°F (37.8°C).
