BS EN 16270:2015规定了汽油中高沸点成分的测定方法 EN 228[1]和符合CEN/TS 15293[2]的乙醇（E85）汽车燃料，通过毛细管气体 使用火焰离子化检测的色谱法。该方法适用于高沸点材料，例如 脂肪酸甲酯（FAME）或柴油，沸点大于或等于1-甲基萘。本欧洲标准适用于蒸汽压力低到足以在室温下取样的材料 环境温度，涵盖至少100°C的沸腾范围。 这种方法特别注意脂肪 酸甲酯。在汽油中，高沸点馏分的测量范围约为0.7%（m/m）至2.5%（m/m）。对于FAME分数，范围为约0.2%（m/m）至约2%（m/m）。在乙醇（E85）汽车燃料中，高沸点馏分的测量范围约为0.2% （m/m）至约2,2%（m/m），对于FAME分数，范围为约0,05%（m/m）至约1,5%（m/m）。注1:计算FAME分数时，该方法仅考虑C18 FAME化合物。注2:在本欧洲标准中，术语“%（m/m）”和“%（V/V）”用于表示 分别是质量分数和体积分数。警告——使用本欧洲标准可能涉及危险材料、操作和安全 设备本欧洲标准并非旨在解决所有相关的安全问题 与它的使用。本标准的使用者有责任建立适当的安全和环境保护措施 并在使用前确定监管限制的适用性。交叉引用:EN 14214EN ISO 3170ISO 3170EN ISO 3171ISO 3171EN 228CEN/TS 15293EN ISO 4259ISO 4259购买本文件时提供的所有现行修订版均包含在购买本文件中。

BS EN 16270:2015 specifies a determination method of high boiling components in petrol according to EN 228 [1] and ethanol (E85) automotive fuels according to CEN/TS 15293 [2] by capillary gas chromatography using flame ionization detection. This method is applicable to high boiling material, such as fatty acid methyl ester (FAME) or diesel fuel, having a boiling point greater than or equal to 1-methylnaphthalene.This European Standard is applicable to materials having a vapour pressure low enough to permit sampling at ambient temperature and covers a boiling range of at least 100 °C. This method pays special attention to fatty acid methyl esters.In petrol the measurement range for the high boiling fraction is from about 0,7 % (m/m) to about 2,5 % (m/m).For the FAME fraction the range is from about 0,2 % (m/m) to about 2 % (m/m).In ethanol (E85) automotive fuel the measurement range for the high boiling fraction is from about 0,2 % (m/m) to about 2,2 % (m/m), for the FAME fraction the range is from about 0,05 % (m/m) to about 1,5 % (m/m)NOTE 1 When calculating the FAME fraction, this method only takes the C18 FAME compounds into account.NOTE 2 For the purposes of this European Standard, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.WARNING -The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard 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.Cross References:EN 14214EN ISO 3170ISO 3170EN ISO 3171ISO 3171EN 228CEN/TS 15293EN ISO 4259ISO 4259All current amendments available at time of purchase are included with the purchase of this document.
