GB/T 8243.1-2003 Methods of test for full-flow lubricating oil filters for internal combustion engines--Part 1: Differential pressure/flow characteristics (English Version)
This part of GB/T 8243 specifies the test for determining the differential pressure-flow characteristics of full-flow oil filters for internal combustion engines. The test specifies the use of oils of two viscosities to evaluate the performance of the filter when using low temperature oils and normal operating temperature oils.
