According to public standard information, GB/T 2433-2001 "Determination of sulfate ash in additive and additive lubricating oils" stipulates a method for determining the ash content in additive and additive lubricating oils by sulfate ash method. This method calculates the mass fraction of sulfate ash by igniting, sulfurizing and burning the sample to a constant weight to evaluate the overall level of metal additives and impurities in the lubricating oil. It is an important indicator for judging the mass and additive stability of the oil. Analytical Balance, high temperature muffle furnace, porcelain crucible, drying device and electric heating plate are mainly used in the determination process. The operation needs to strictly control the burning temperature and constant weight conditions to ensure the accuracy and reliability of the results.
