What is ISO 4548-5 about?
ISO 4548-5 is the fifth part of the multi-series standard that 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.
Tests described in ISO 4548-5 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 the customer.
Who is ISO 4548-5 for?
ISO 4548-5 on cold start simulation and hydraulic pulse durability test is useful for:
- Mechanical engineers
- Chemical engineers
- Manufacturers of combustion engines
- Researchers and testers of engineers
Why should you use ISO 4548-5?
The internal combustion (IC) engine is a class of heat engine wherein the chemical energy of the fuel is transformed into shaft work.
The ISO 4548-5 specifies a method of calculating the ability of full-flow lubricating oil filters manufactured with metal pressure vessel material to withstand internal pressure surges.
ISO 4548-5 provides tests that can be conducted on separate filters to simulate in-service conditions and to verify the capacity of the filter canister and seal to withstand these conditions.
Overall, ISO 4548-5 guidelines cover a wide range of rigs test and fluid tests, durability tests, and accuracy tests that improve the efficiency of combustion engines and bring them to a sustainable and cost-effective level.
What’s changed since the last update?
BS EN ISO 4548-5:2020 supersedes BS EN ISO 4548-5:2013. BS EN ISO 4548-5:2020 includes some technical changes concerning BS EN ISO 4548-5:2013. These include:
- The test system schematic has been revised to include updated instrumentation
- The cold start simulation test and hydraulic pulse durability procedures have been combined into Clause 8
- The names of the tests have been revised to the “extreme” and “normal” pressure surge tests
- The test system setup has been defined in more detail
- A round-robin test has been added to be performed to validate the changes. The results have been summarized in a new informative annex (see Annex B)
