标准摘要
[中文适用范围]： 本文件描述了测定未使用过的含添加剂润滑油和配制用添加剂浓缩液中的硫化物灰分质量分数的方法。这些添加剂通常包含以下一种或多种金属：钡、钙、镁、锌、钾、钠和锡。元素硫、磷orus和氯也可以以结合形式存在。本文件也适用于脂肪酸甲酯（FAME）。该试验方法适用于硫化物灰分含量在质量分数为 \(0.005\%\) 到 \(25.00\%\) 之间的产品。对于硫化物灰分含量低于质量分数 \(0.02\%\) 的情况，本文件仅限于分析不含添加剂的润滑油产品。本文件不用于含铅发动机油的分析，也不用于非含添加剂润滑油的分析，对于这些润滑油，ISO 6245 是适用的。 [外文原描述]： This document describes a procedure for the determination of the mass percentage of sulfated ash from unused lubricating oils containing additives and from additive concentrates used in compounding. These additives usually contain one or more of the following metals: barium, calcium, magnesium, zinc, potassium, sodium and tin. The elements sulfur, phosphorus and chlorine can also be present in combined form. This document is also applicable to fatty acid methyl esters (FAME). This test method is applicable to products having sulphated ash contents in the range mass fraction of 0,005 % to 25,00 %. Application of this procedure to sulfated ash levels below a mass fraction of 0,02 % is restricted to oil products containing ashless additives. This document is not intended for the analysis of used engine oils containing lead, nor for the analysis of non-additive lubricating oils, for which ISO 6245 is suitable.
