I emailed them after you posted the question so here is the "proof" :
Thank you for the email and question. We use ISO-4548 section 12 - Multi-Pass Efficiency Test. This test is performed by 3rd party lab in TX. ISO 4548-12 is an established standard test procedures to measure the performance of full-flow lubricating oil filters for internal combustion engines. Basically, the test equipment includes a simulation of lubricant flow from one side of the filter, where containment is added to the lubricant (preset mix in accordance with ISO 12103-A3) and it flows through the filters, to the clean side. The test system is includes highly sensitive particle counters that records the amount of contaminate by particle size, before and after the filter. In other words, containment is added to clean oil, the particle counters record the quantity by particle size before and after the filter. Typical the flow rate is set to at a rate of 3 gallons per min or 12L/M.. The test is terminated once the deferential pressure (the deference is pressure between the upstream and downstream) reaches a preset level (typically 8-10 PSI),. The termination point is set based on the specification of the opening pressure of the by-pass relief valve. The test results covers 3 key areas:
Efficiency - is reported by particle size.. typically the results are reported at those levels unless otherwise requested 7 micron, 10, 15, 20, 25, 30, 35, 40
Capacity in grams, which measure the amount of containment captured by the filter media
Differential pressure throughout the test
I hope this is what you were looking for.
Thanks again.
