AbolishedDetermination of apparent viscosity of engine oils using the cold-cranking simulator
发动机油表观黏度的测定 冷启动模拟机法
Application Summary AI generated
This standard specifies a test method for measuring the apparent viscosity of engine oils at low temperatures using a cold-cranking simulator (CCS). It is applied in the petroleum industry to evaluate the low-temperature flow properties of engine oils, ensuring they provide adequate cranking and starting performance in cold climates. The method is critical for quality control and formulation of lubricants used in automotive engines.
