Methods of test for full-flow lubricating oil filters for internal combustion engines — Part 5: Test for hydraulic pulse durability
Preview
Summary
This document specifies a method of testing the ability of full-flow lubricating oil filters manufactured
with metal pressure vessel materials for internal combustion engines to withstand an internal pressure
surge. Normally surges occur 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.
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.
