ISO 4548-14:2016 establishes standardized procedures for testing full-flow lubricating oil filters with composite pressure-vessel housings for internal combustion engines. It evaluates their ability to withstand internal pressure surges and repeated pressure variations at specified operating temperatures.
The standard covers test equipment, test liquids, temperature conditions, instrumentation accuracy, cold-start simulation, hydraulic pulse durability testing, pressure-cycle waveforms, inspection procedures, and test-report requirements. It also provides default test pressures and cycle counts for light-duty spin-on filters, heavy-duty spin-on filters, and detachable filters with disposable elements.
Application Scope: Applicable to spin-on filters and detachable filters with disposable elements constructed from composite materials and used in full-flow lubricating oil systems for internal combustion engines.
