本文件规定了一种荧光指示剂吸附法，用于测定 在315℃以下蒸馏的石油馏分中，浓度范围为5%（V/V）至99%（V/V）的芳烃、0,3%（V/V）至55%（V/V）的烯烃和1%（V/V）至95%（V/V）的饱和烃。该方法可适用于这些范围以外的浓度，但精度尚未确定。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 %(V/V)to 99 %(V/V)aromatic hydrocarbons, 0,3 %(V/V)to 55 %(V/V)olefins, and 1 %(V/V)to 95 %(V/V)saturated hydrocarbons in petroleum fractions that distil below 315 °C. This method can apply to concentrations outside these ranges, but the precision has not been determined.All current amendments available at time of purchase are included with the purchase of this document.
