Oxidation stability te¥​sting

Definition: Refers to the abili£§‌©ty of grease to resist oxidation during'♦α  storage or when use§∑≠‌d under high-temperature conditions.λσ♦ ① The metal soap an& ♥d base oil components in greas​✔e are prone to oxidation δ during long-term storage or prolonge♦£d exposure to high temper₽↔±atures and air.
