ActiveMethods of test for full-flow lubricating oil filters for internal combustion engines - Part 9: Inlet and outlet anti-drain valve tests
内燃机全流式机油滤清器试验方法 第9部分：进、出口止回阀试验
Application Summary AI generated
This standard specifies test methods for evaluating the performance of inlet and outlet anti-drain valves in full-flow lubricating oil filters for internal combustion engines. It is applied in the automotive and industrial engine sectors to ensure that oil filters prevent oil drainage from the filter housing when the engine is off, maintaining oil system priming and reducing dry-start wear. The tests are conducted during filter development, quality control, and type approval to verify valve sealing effectiveness under specified pressure and flow conditions.
