ISO 4548-14 Lubricating Oil Filters - Cold Start Simulation Test for Composite Filter Housings

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4548-14 testing. ISO 4548-14 specifies a method for testing the ability of full-flow lubricating oil filters manufactured with composite pressure vessel materials for internal combustion engines to withstand an application-experienced internal pressure surge and cyclic internal pressure variations at certain operating temperatures.

These tests are designed to apply to spin-on filters and detachable filters with disposable elements made of composite materials.

ISO 4548-14 is a standard that specifies methods for testing the durability of full-flow lubricating oil filters for internal combustion engines with composite filter housings.

Specifically, this standard covers two types of tests:

• Cold Start Simulation: This test evaluates the filter's ability to operate effectively in cold weather conditions. The filter is cooled to a certain temperature and then a stream of hot oil is passed through it to simulate the thermal shock that occurs during cold start-up. During this test, the filter's ability to remove contaminants from the oil is evaluated.
• Hydraulic Shock Endurance: This test evaluates the filter's ability to withstand pressure surges that occur during engine operation. The filter is subjected to a series of hydraulic pulses that simulate pressure changes while the engine is running. During this test, the filter's ability to maintain its structural integrity and filtration efficiency is evaluated.

Both tests are performed using composite filter housings made from a combination of different materials such as plastics, metals and fibers. Such filter housings are widely used in modern engines because they offer a number of advantages over traditional metal housings, such as lower weight, better corrosion resistance and lower cost.

ISO 4548-14 provides detailed instructions on how to conduct these tests, including the specific equipment and conditions that should be used. By following these methods, manufacturers can ensure that full-flow lubricating oil filters can meet the demands of modern engines and provide reliable performance under a variety of conditions.
