Test Method for the Determination of Total Acidity in Polyol Ester and Diester Gas Turbine Lubricants by Automatic Potentiometric Titration 用自动电位滴定法测定多元醇酯和柴油机润滑油中总酸度的试验方法
发布日期: 2024-03-18
该试验方法描述了通过电位滴定技术测定新型和降解的多元醇酯和二酯基燃气轮机润滑剂的总酸值(TAN)的程序。经验证,该方法的酸度范围为0.05至6.0 mg KOH g-1。该方法也可适用于测定该范围以外的酸度和其他类别的润滑剂。
The test method describes the procedure for determination of the total acid number (TAN) of new and degraded polyol ester and diester-based gas turbine lubricants by the potentiometric titration technique. The method was validated to cover an acidity range of 0.05 to 6.0 mg KOH g-1. The method may also be suitable for the determination of acidities outside of this range and for other classes of lubricants.
