ActiveStandard test method for determining the friction and wear properties of manual transmission fluid using a high-frequency—Linear-oscillation（SRV）test machine
手动变速箱润滑油摩擦磨损性能的测定 SRV试验机法
Application Summary AI generated
This standard specifies a laboratory test method using a high-frequency, linear-oscillation (SRV) test machine to evaluate the friction and wear properties of manual transmission fluids. It is applied in the automotive lubricant industry for quality control, product development, and performance benchmarking of gear oils used in manual transmissions. The test simulates the oscillating sliding contact conditions found in manual transmission components to assess lubricant effectiveness under controlled temperature and load.
