Oil Filter Pressure Difference-Flow Characteristic Tester ISO 4548-1:2002

Products Introduction：

The oil filter pressure difference-flow characteristic tester is a test used to measure the pressure difference-flow characteristic of the full-flow oil filter of the internal combustion engine. The test specifies the use of two oil viscosities to evaluate the performance of the filter with low temperature oil and normal operating temperature oil.

Test Principle：

The test solution is brought to the set temperature by means of a heater or cooler. The pressurizing pump pumps the test liquid into the test workpiece for circulation, during which 5-8 flow points and differential pressure values are read according to the test specifications. And through the same operation specification test and numerical admission of the two liquids. Automatically generate differential pressure and flow characteristic curves and test reports.

Standard:

ISO 4548-1:2002

Filter Under Test:

A. Spin-on filters that do not include a filter seat (which may or may not have a filter element bypass valve) are included in the replaceable assembly.

B. The replaceable assembly includes a filter seat and a spin-on filter with a filter element bypass valve.

C. Other filters, usually replaceable filters, often come with their own filter seat.
