2、riginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope*1.1 This test method covers the determination of the boilingrange dist
3、ribution of petroleum products and biodieselformulations,B5,B10,and B20.It is applicable to petroleumdistillates having a final boiling point not greater than 538 Cor lower at atmospheric pressure as measured by this testmethod.The difference between the initial boiling point and thefinal boiling po
4、int shall be greater than 55 C.1.2 The test method is not applicable for analysis ofpetroleum distillates containing low molecular weight compo-nents(for example naphthas,reformates,gasolines,full rangecrude oils).Materials containing heterogeneous mixtures(forexample,alcohols,ethers,acids or esters
5、,except biodiesels)orresidue are not to be analyzed by this test method.See TestMethods D3710,D7096,D6352,or D7169.1.3 This test method uses the principles of simulated distil-lation methodology.This test method uses gas chromato-graphic components that allow the entire analysis from sampleto sample
6、 to occur in 5 min or less.In these instruments thecolumn is heated directly at rates 10 to 15 times that of aconventional gas chromatograph and thus the analysis time isreduced from sample to sample.1.4 The values stated in SI units are to be regarded asstandard.No other units of measurement are in
