ISO-4548-4 › Methods of test for full-flow lubricating oil filters for internal combustion engines -- Part 4: Initial particle retention efficiency, life and cumulative efficiency (gravimetric method)
The following bibliographic material is provided to assist you with your purchasing decision:
This part of ISO 4548 specifies tests for determining the performance of full-flow lubricating oil filters for internal combustion engines as follows.
Section 2: Initial particle retention efficiency. This gives the test procedures and parameters for the determination of the initial particle retention efficiency of lubricating oil filter elements under defined test conditions. By reporting the results in accordance with subclause 2.6, the probable retention efficiency for any particle size may be derived. The retention efficiency is determined by the gravimetric method.
Section 3: Life and cumulative efficiency. This gives the test procedures and parameters for the determination of element life and cumulative efficiency of lubricating oil filters. The cumulative efficiency is determined by the gravimetric method.
