Cabin filters are used for comfort purposes but also as safety equipment. Especially the use of gas filters in protection cabins requires knowledge about the cleaning efficiency at the expected ambient air conditions. With a series of experimentally determined test results the ILK Dresden shows the influence of air temperature, humidity, air velocity and test gas concentration on the gas separation.
By upgrading a test rig designed according to ISO 11155 it became possible to test filters and adsorptive materials also at low flowrates, high humidity and with toxic gases like SO2, NH3 and H2S. The ILK proposes a test routine to qualify cabin filters, which should be tested in a comparable way to standards for mask filters of personal protection equipment. Essential parts of actual standards are included or adapted in the new test routine. So a basis was made to create a new official test standard...
