OS GSO ISO 4263-4:2008 Scope
This part of ISO 4263 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[5]. 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.
