Popis

BS EN ISO 4263-4:2006


This standard BS EN ISO 4263-4:2006 Petroleum and related products. Determination of the ageing behaviour of inhibited oils and fluids. TOST test is classified in these ICS categories:
  • 75.100 Lubricants, industrial oils and related products

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.
