1.1 This test method covers the quantitative determination of individual hydrocarbons in liquefied petroleum (LP) gases and mixtures of propane and propene, excluding high-purity propene in the range of C1 to C5. Component concentrations are determined in the range of 0.01 to 100 volume percent. 1.2 This test method does not fully determine hydrocarbons heavier than C5 and non-hydrocarbon materials, and additional tests may be n
