标准范围

ISO 4263:2006规定了测定ISO 6743-6中定义的CKC、CKD、CKS和CKT类齿轮油老化性能的方法。空气的存在和温度的升高加速了老化，通过100°C下运动粘度的变化、不溶物含量（沉淀数）以及酸值的增加、过滤产生的沉淀物含量、添加剂含量的变化和红外氧化来评估油的降解。

ISO 4263:2006 specifies a method for the determination of the ageing behaviour of gear oils of categories CKC, CKD, CKS and CKT as defined in ISO 6743-6. The ageing is accelerated by the presence of air and elevated temperatures, and the degradation of the oil is assessed by the change in kinematic viscosity at 100 °C, the insoluble content (precipitation number), and possibly the acid number increase, the sediment content by filtration, the additives content variation and the infra-red oxidation.
