Petroleum and related products. Determination of the ageing behaviour of inhibited oils and fluids. TOST test - Procedure for industrial gear oils Ingestion-build-83346 What is BS 5353 -1 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
