The DOP test is used to evaluate particle penetration and air flow resistance properties for a variety of filtration materials, including HEPA filters, NIOSH respirators and filter media. The test is performed in compliance with 42 CFR Part 84 and NIOSH Procedure No. RCT-APR-STP-0051-0056, 2005 and is necessary for pre-qualification for NIOSH certification of respirators. Nelson Laboratories has extensive experience testing filters and other filtration devices.

Study OutlineThe DOP aerosol test is a widely accepted method for evaluating particle penetration and air flow resistance properties of a variety of filtration materials (e.g., breathing system filters, NIOSH respirators and face masks). The procedure employs an aerosol of DOP using a TSI® CERTITEST® Model 8130 Automated Filter Tester.
Test articles are challenged with particles of the most penetrating particle size range, 0.3 µm. Filtration efficiency measurements can be determined up to 99.999%. Samples can be tested at flow rates up to 90 liters per minute (LPM). The filtration requirement for HEPA filters is 99.97% at 0.3 µm using the DOP test.
