Methods of Test for Full-Flow Lubricating Oil Filters for Internal Combustion Engines - Part 1: Differential Pressure/Flow Characteristics
|Publication Date:||15 September 1997|
|ICS Code (Internal combustion engines):||27.020|
This part of IS0 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.
