METHODS OF TEST FOR FULL-FLOW LUBRICATING OIL FILTERS FOR INTERNAL COMBUSTION ENGINES - PART 5: COLD START SIMULATION AND HYDRAULIC PULSE DURABILITY TEST (ISO 4548-5:1990, IDT)
This Malaysian Standard specifies a method of testing the ability of full-flow lubricating oil filters for internal combustion engines to withstand an internal pressure surge such as occurs when an engine is started from cold, and cyclic internal pressure variations experienced during Operation.
These tests are intended for application to spin-on type filters and detachable filters with disposable elements with a maximum flow rate of 100 l/min. The tests may be applied to other filters if thought appli- cable by agreement between the filter manufacturer and the purchaser.
