1.1 This test method covers the determination of the boiling range distribution of petroleum products and biodiesel formulations, B5, B10, and B20. It is applicable to petroleum distillates having a final boiling point not greater than 538C or lower at atmospheric pressure as measured by this test method. The difference between the initial boiling point and the final boiling point shall be greater than 55C. 1.2 The test method is not applicable for analysis of petroleum distillates containing low molecular weight components (for example naphthas, reformates, gasolines, and full-range crude oils). Materials containing heterogeneous components (for example alcohols, ethers, acids, or esters) or residue are not to be analyzed by this test method. See Test Methods D3710, D7096, D6352, or D7169. 1.3 This test method uses the principles of simulated distillation methodology. This test method uses gas chromatographic components that allow the entire analysis from sample to sample to occur in 5 min or less. In these instruments, the column is heated directly at rates 10-15 times that of a conventional gas chromatograph and, thus, the analysis time is reduced from sample to sample. 1.4 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are provided for information only and may be included as parenthetical values. 1.5 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.
This standard is needed because it saves time since the analysis is carried out in about 2-3 min from sample to sample. At present, the published method takes around 20 min.
