Description / Abstract:
This part of ISO 4548 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 can be applied to other filters, if thought
applicable, by agreement between the filter manufacturer and the
purchaser.
NOTE This test is not intended to replace simulated
environmental testing (e.g. at very low temperatures). If such
testing is required, it will be the subject of negotiation between
the supplier and customer.
