Sample dissolved in a mixed solvent containing a small amount of water, with a standard solution of potassium hydroxide isopropanol as a titrator for potential titration, the used pair of electrodes for glass indicating electrodes glycemic reference electrodes, on the hand-drawn or automatic drawn curve of potential titration dose only the obvious jump point as the end point, if no obvious jump point, then the corresponding new assigned potential value of non-aqueous acid or alkaline buffer solution as the end point of titration.

1. Acid components of new or used oils refer to additives or oils in the process of use degradation products such as oxidation products etc., these substances can be measured by alkaline titration and their relative content, acid value is in specified conditions to measure the amount of these substances in oils, acid value can be used to control the quality of lubricating oil, sometimes can also be used to measure the degradation of lubricating oil in the process of use, but acid value as a lubricating oil waste indicator must be determined by experience.
2.Since oxidation products can affect acid values, while organic matter also changes significantly in corrosion conditions, this method cannot be used to predict the corrosion performance of oils during use, such as acid values and the degree of corrosion of oils to metals.
