The gas chromatographic determination of the boiling point distribution of hydrocarbon solvents can be used as an alternative to conventional distillation methods for control of solvents quality during manufacture, and specification testing.
Boiling point distribution data can be used to monitor the presence of product contaminants and compositional variation during the manufacture of hydrocarbon solvents.
Boiling point distribution data obtained by this test method are not equivalent to those obtained by Test Methods D 86
1.1 This test method covers the determination of the boiling point distribution of hydrocarbon solvents by capillary gas chromatography. This test method is limited to samples having a minimum initial boiling point of 37°C (99°F), a maximum final boiling point of 285°C (545°F), and a boiling range of 5 to 150°C (9 to 270°F) as measured by this test method.
1.2 For purposes of determining conformance of an observed or calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E 29
1.3 The values stated in SI units are standard. The values given in parentheses are for information purposes only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
