DIN EN 1822 and DIN EN ISO 29463
Test standard for HEPA filters
(EPA, HEPA and ULPA)
Filter classes of the DIN standard EN 1822
The DIN standard EN 1822 is a filter standard for HEPA filters and includes the filter classes:
- EPA filter (Efficient Particulate Air filter) = high-performance particle filter
- HEPA filter (High-efficient Particulate Air filter) = suspended matter filter
- ULPA filter (Ultra Low Penetration Air) = high-performance particulate matter filter
The standard enables a method for testing the separation efficiency based on a particle counting method using a liquid (or alternatively a solid) test aerosol and enables a uniform classification of the HEPA filters according to the separation efficiency. It covers testing the filtration performance of high performance particulate filters (EPA), particulate matter filters (HEPA) and high performance particulate matter filters (ULPA) at the manufacturing plant.
Innovation DIN EN ISO 29463
The test standard DIN EN 1822 forms the basis for the new ISO 29463 and applies to high-performance particle filters and high-performance particulate matter filters (EPA, HEPA and ULPA). At the same time, the new standard replaces parts of DIN EN 1822. The introduction of ISO 29463 has the consequence that air filters are classified according to EN 1822 Part 1, but tested according to ISO 29463 Parts 2-5.
