I thought this was interesting, as some company has to make these certified test machines. Here's one, in India of all the places. If anyone is interested in taking a 2nd mortgage out on their house and buying a certified ISO 4548-12 test bench to do oil filter efficiency testing in their garage, then this is for you. I have no idea what the cost is, couldn't find it on the website ... but I'm sure is a ton of cash. Would probably have to email the place to find out what it really costs.
Here's the website of the company that builds and sells them. They also have other test benches for other ISO 4548 tests.
