    Abstract - (Show below) - (Hide below)

    Defines tests for determination of the differential pressure/flow characteristics of full-flow lubricating of filters for internal combustion engines. Deals with oils at two viscosities, one for assessment of the filter performance with a cold oil and the other for assessment of its performance with an oil at typical operating temperature.

    Scope - (Show below) - (Hide below)

    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.
