With cleanrooms often protecting mission critical environments, filter integrity and efficiency is vital; HEPA filters are tested to 99.99% @ 0.3 micron efficiency with ULPA filters tested to 99.9995% @ 0.12 micron. Dispersed Oil Particulate ( DOP ) testing, also known as filter integrity testing, is the process in which the integrity of your HEPA (High Efficiency Particulate Air) or ULPA (Ultra Low Penetration Air) filter is challenged through introducing particulates and measuring the output. The bottom line of this standard is that filters that meet the specification are able to successfully filter particulates in the air to an efficiency of 99.97%. It is important that the proper flow rate through the filters is established prior to testing. In-Situ Filter Testing (DOP ) uses a smoke generator, injecting a standard Aerosol upstream of the filters. It is believed that the original HEPA filters were tested at a mass mean diameter of ~ 0.3 ╬╝m, since this was the size of the radionuclides of concern. Geeignet sind Photometer oder die Kombination von Partikelzähler und Verdünnungsapparatur gemäß Prüfungsart prEN 12469.Die Kombination von Partikelzähler und Verdünnungsapparatur ist aufwendiger als das Photometer, erlaubt aber Messungen von Laminar-Flow Anlagen mit Luftvolumenströmen bis zu 100.000 m³/h.Bei Laminar-Flow Geräten oder Anlagen mit einem grossen Umluftanteil ist nur mit dieser Testmethode eine Aussage über den Zustand der Anlage zu erreichen. Typically, HEPA filters capture up to 99.97% of particles as small as 0.3 microns. Für diesen Test benötigen sie den Aerosol-Generator und ein geeignetes Mess-System mit einem Messbereich über 5 bis 6 Dekaden. HEPA efficiency is rated using a thermal dioctyl phthalate (DOP) test.
