BS EN 15199-1 This document specifies a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. The standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and a boiling range of at least 100 °C. The standard is applicable to distillates with initial boiling points (IBP) above 100 °C and final boiling points (FBP) below 750。C, for example, middle distillates and lubricating base stocks. The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphtha’ s, reformates, gasolines) or middle distillates like Diesel and Jet fuel. Petroleum or petroleum products containing blending components which contain heteroatoms [for example alcohols, ethers, acids, or esters) or residue are not to be analysed by this test method. NOTE For the purposes of this document, the terms “% (m/m)” and“% (V/V)” are used to represent respectively the mass fraction and the volume fraction. WARNING一The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.A test portion is introduced into a gas chromatographic column, which separates hydrocarbons in the order of increasing boiling point. The column temperature is raised at a linear reproducible rate and the area under the chromatogram is recorded throughout the analysis. Bolling points are assigned to the time-axis from a calibration curve obtained by running a mixture of known n-alkanes, covering the sample boiling range, under the same conditions. From these data, the boiling range distribution is obtained. Several SIMDIS methods are standardized test methods and each one is dedicated to a certain boiling point range or product. EN ISO 3924 [1] is limited to products having an initial boiling point greater than 55。C, a final boiling ; point lower than 538。C and having a vapour pressure sufficiently low to permit sampling at ambient temperature. EN 15199-2 is applicable to materials with initial boiling points (IBP]) above 100 °C and final boiling points (FBP) above 750 °C，for example, heavy distillate fuels and residuals. The method is not applicable to bituminous samples. EN 15199-3 is applicable to crude oils. The boiling range distribution and recovery (3.8) up to C100 or C120 can be determined.BS EN 15199-1 pdf download.
