METHODS OF TEST FOR FULL-FLOW LUBRICATING OIL FILTERS FOR INTERNAL COMBUSTION ENGINES - PART 2: ELEMENT BY-PASS VALVE CHARACTERISTICS
出版：International Organization for Standardization
專家解讀視頻
Defines tests for determination of the element by-pass valve characteristics of full-flow lubricating oil filters for internal combustion engines. Covers oils at two viscosities, for assessment of the performance of an element by-pass valve with a cold oil or for assessment of performance with an oil at typical operating temperature.
