Methods of test for full-flow lubricating oil filters for internal combustion engines -- Part 1: Differential pressure/flow characteristics
This part of ISO 4548 specifies tests for determining the differential pressure/flow characteristics of full-flow lubricating oil filters for internal combustion engines.
Tests are specified with oils at two viscosities, one to assess the performance of a filter with a cold oil and the other to assess its performance with an oil at a typical operating temperature.
