本文件规定了用火焰离子化检测毛细管气相色谱法测定石油产品沸点分布的方法。本标准适用于蒸汽压力低到足以允许在环境温度下取样，且沸点范围至少为100°C的材料。本标准适用于初始沸点（IBP）高于100°C，最终沸点（FBP）高于750°C的材料，例如，重馏分燃料和残渣。该方法不适用于沥青样品。 本试验方法不适用于含有低分子量组分（例如石脑油、重整油、汽油）或柴油和喷气燃料等中间馏分的石油或石油产品的分析。 不使用本试验方法分析含有杂原子（例如醇类、醚类、酸类或酯类）或残渣的混合成分的石油或石油产品。 注:在本文件中，术语“%（m/m）”和“%（V/V）”分别表示质量分数和体积分数。 警告-使用本文件可能涉及危险材料、操作和设备。本文件并非旨在解决与其使用相关的所有安全问题。本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性。

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 which have a boiling range of at least 100 °C. The standard 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. The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines) or middle distillates like Diesel and Jet fuel. Petroleum or petroleum products containing blending components, which contain hetero atoms (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 - The use of this document may 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.
