Respirators intended for submission to NIOSH may require NaCl, DOP, valve leak, and inhalation/exhalation tests to verify conformity to NIOSH standards prior to submission. Nelson Labs offers these pre-submission testing services.
The Sodium Chloride Aerosol Challenge (NaCl) – This test uses a widely accepted method for evaluating particle penetration and airflow resistance properties of a variety of filtration materials. Respirators must be tested by the manufacturer or a third-party laboratory before submitting to NIOSH for certification; other materials, such as breathing system filters, face masks, etc. are tested to determine filtration efficiency for marketing purposes.
The Dioctyl Phthalate (DOP) test is used to evaluate particle penetration and airflow 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 prior to submission for NIOSH certification of respirators. Nelson Labs has extensive experience testing filters and other filtration devices.
Testing is performed in compliance with 42 CFR Part 84 and NIOSH Procedure No. RC-APR-STP-0057, 0058 and 0059. Nelson Labs has extensive experience testing filters and other filtration devices.
