1.1 ,This test method covers the determination of the boiling range distribution of petroleum distillate fractions. The test method is applicable to petroleum distillate fractions having an initial boiling point greater than 174 ,°,C (345 ,°,F) and a final boiling point of less than 700 ,°,C (1292 ,°,F) (C10 to C90) at atmospheric pressure as measured by this test method.
