JASO M348 ATF and T903 Motorcycle Engine Oil Friction (high speed plate clutch) In addition to lubricant evaluation, the SAE No. 2 test stands can be configured to evaluate clutch material frictional characteristics.

두 고체가 각각의 다른 운동을 하면서 맞닿아 있거나, 외력이 있는 상황에서 상대적인 움직임으로 운동을 시작하거나 할 때에 마찰력은 운동에 반대 방향으로 접촉면을 따라 발생한다. 이 힘의 특징은 마찰특성의 특징이 될 수 있다. 본 규격에서는 마찰 크러치를 사용하여 동적 및 정적 마찰시험을 통해 얻어진 마찰계수 에 의해 자동 변속 윤활유 성능에 관계된 마찰특성을 표현하고자 한다. b. 기준의 변속 유체(RTF) 참고용 자동 변속 유체로는 T-lll을 사용하여 시험. 마찰계수는 동적 그리고 정적 …

We provide standardized and bespoke tests of transmission fluids, gear lubricants, tractor, industrial hydraulic and more. We can also evaluate the components that use these fluids. Standardized protocols include industry standard procedures from SAE International, ASTM International and JASO (Japanese Automotive Standards Organization).

JASO-M348 Friction Characteristics Test Method for Automatic Transmission Fluids, Material & Sur

Full-scale clutch tests, such as the JASO M348 or any other OEM-specific test protocol run on the SAE No. 2 Friction Test Machine, are typically used to obtain friction data, but these tests are both expensive and time consuming.
