The new ISO 16890 standard is set to completely transform the way we think about air filters. And now it's here. MANN+HUMMEL's Industrial Air team has been involved in developing the new standard from the start. So we've been busily making preparations and now have a fully-functioning test laboratory ready for the new standard.
Testing an air filter according to ISO 16890 is a much more extensive process than the EN 779 standard being replaced. EN 779 challenged a filter with just one particle size-0.4 µm, which made the process straightforward, but didn't reflect what happens outside of the laboratory, in real life. Under ISO 16890, filters are tested against 12 different particle size groups from 0.3 µm up to 10 µm.
Testing a filter is done by challenging it with a test aerosol and comparing the number of particles going in against the number of particles that get past the filter on the clean air side. As ISO 16890 introduces a wider range of particle sizes, testing is no longer just a case of counting upstream versus downstream. Now, test rigs need to sort and analyse different sized particulate across 12 channels. This means that although the test is much more realistic, it does require the latest sophisticated equipment.
The added benefit of this is that the new equipment is much more accurate than the previous EN 779 test rigs. So it gives us a much clearer picture of a filter's performance too.
We have just completed the fit out of our Swedish research facility with an all new laboratory that's ready for ISO 16890. It's a 240 m² space with full air-conditioning control for temperature and humidity to create the perfect test environment. Contained within the laboratory is a brand new ISO 16890 test rig capable of carrying out the more demanding tests of the new standard. And alongside this, sits a raft of other testing equipment including a burst pressure test rig for pushing our products to the limit (and beyond).
Later this year, this new equipment will be joined by an oil mist rig for the testing of oil mist eliminators used in metalworking. And a water separation machine to test the performance of our range of marine weather louvers will be installed in 2017.
The aim of all this investment is to analyse the performance of our products in as realistic an environment as possible. That way, we can ensure that our products are ready for use in your air handling unit.
So, we have readied ourselves for the new ISO 16890 standard. But what about you? Are you ready? You can learn all you need to know about the new standard with our new guide. But if you're pressed for time, you can get the key facts in just three minutes with our in-brief article that outlines the most important aspects of ISO 16890.
