The TSI Automated Filter Testers 8127 & 8130 were designed for the American test method. NIOSH uses these testers for certification measurements and therefore many filter manufacturers supplying to the American market use them for their quality control as well as for the development of new filter media. We thought out a way to modify these testers to give EN 143 equivalent test results. In November 2007, a measurement campaign was run at BGIA (accredited German respirator filter certification laboratory at Sankt Augustin).

Based on the results of the measurement campaign, BGIA approved that the modified TSI 8130 can be used for quality control measurements in accordance with EN 143 (3).Click here to view a copy of the test reportand an English translation. Later this year, we plan another measurement campaign with BGIA to add approval for EN 143 certification testing to the approval for quality control testing.
