Hydrocarbon Concentration In

1.1 this test method covers the determination of hydrocarbon types over the concentration ranges from 5 to 99 by volume aromatics, 0.3 to 55 by volume olefins, and 1 to 95 by volume saturates in petroleum fractions that distill below 315 c.This test method may apply to concentrations outside these ranges, but the precision has not been determined.
