Test Data for Objectively Selecting Oil Filters

[RustyJC]

The following is from Noria's Filtration Tips e-newsletter and should be of interest in future oil filter wars threads:

Apart from the data on the multipass filter test, what other ISO standards exist for the evaluation of filter performance that I can use to objectively select a filter?"



The ISO standard for multipass testing (ISO 16889) has changed to require filter manufacturers to publish their data for the beta ratios across a wide size range, that is, at 2, 20, 75, 100, 200 and 1,000 microns.



Historically, filter beta ratios were published at either 75 or 200 with an absolute rating (per ISO 4572). The new standard gives a better interpretation of the filter's overall performance, and can be better compared against competitor offerings.



In addition to the new multipass data, consider the following data:



ISO 2941 - 1974 - Verification of collapse/burst resistance.



ISO 2942 - 1994 - Verification of fabrication integrity and determination of the first bubble point.



ISO 2943 - 1998 - Verification of material compatibility with fluids.



ISO 3723 - 1976 - Method for end load test.



ISO 3724 - 1976 - Verification of flow fatigue characteristics.



ISO 3968 - 1981 - Evaluation of pressure drop versus flow characteristics.



These additional tests are useful for comparison where the installation may be an unusual lubricant, an extreme contaminant-sensitive workpiece, a high-pressure fluid power system or a safety-critical application. When selecting for a noncritical system with no unusual requirements, evaluation of filter suppliers' multipass data, in addition to other commercial criteria, will normally suffice.

Dang, you are quick on the draw! I read your post before I got the email!

Wouldn't it be easier just to get the one that says "Fleetguard" on it?

Actually, Ken, that's what I do. Then again, we always have those threads stating "Acme brand oil filters are just as good/better than Fleetguard". Well, here's how oil filter performance is measured, so now those on either side of the issue know what data to request to prove their case.

Actually, ISO 16889:1999 is for Hydraulic fluid filters.

The one that covers Oil filters for internal Combustion Engines is:



ISO 4548-12:2000

Methods of test for full-flow lubricating oil filters for internal combustion engines -- Part 12: Filtration efficiency using particle counting, and contaminant retention capacity.



If you go to their web page www.ISO.org you can read all the ISO related tests. Specificly this page.
