BSI | 2021 | 30 |
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 Ā°C. The standard is applicable to distillates with initial boiling points (IBP) above 100 Ā°C and final boiling points (FBP) below 750 Ā°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 naphthaās, 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.
For the purposes of this document, the terms ā% ( m/ m)ā and ā% ( V/ V)ā are used to represent respectively the mass fraction and the volume fraction.
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.
