Respirators intended for submission to NIOSH may require NaCl, DOP, valve leak, and inhalation/exhalation tests to verify that the respirator meets the minimum performance requirements. These tests can be performed by the manufacturer or a third-party laboratory and must follow NIOSH Standard Testing Procedures (STPs) and use appropriate instrumentation. Nelson Labs offers these pre-submission testing services.
The Sodium Chloride Aerosol Challenge (NaCl) uses a widely accepted method for evaluating particle penetration and airflow resistance properties of a variety of filtration materials. 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.
Testing is performed in compliance with 42 CFR Part 84 and NIOSH Procedure No. RC-APR-STP-0057, 0058 and 0059 is necessary prior to submission for NIOSH certification of respirators. Nelson Labs has extensive experience testing filters and other filtration devices.
