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.
NOTE By agreement between filter manufacturer and purchaser, tests on large filters can be conducted on the basis of tests carried out on filters scaled-down in length. The relationship of the filter flow and test dust addition rate to the effective length of the filter medium should be the same in the scaled-down tests as in the full size filter. For the purposes of this part of ISO 4548, a filter having a test flow rate exceeding 100 l/min is considered large.
