ActiveLubricating oils--Determination of aging characteristics--Conradson carbon residue method
润滑油老化特性测定法 (康氏残炭法)
Application Summary AI generated
This standard specifies a method for determining the aging characteristics of lubricating oils by measuring the Conradson carbon residue formed under controlled heating conditions. It is applied in the petroleum industry for quality control and performance evaluation of lubricating oils, particularly in assessing their tendency to form carbon deposits during use in engines, turbines, or hydraulic systems. The method is used in laboratory testing contexts to predict oil degradation and deposit formation under thermal stress.
