TEB-APR-STP-0059 Determination of Particulate Filter Efficiency Level for N95 Series Filters

The TEB-APR-STP-0059 testing is required by NIOSH 42 Part 84 for non-powered air-purifying respirators.  NIOSH regulates all products sold in the US but end users and competitors checking market products have turned to Kinectrics for our NIOSH-type respirator testing.  Kinectrics testing has been useful for type testing and production testing checks or pre-test requirements before submission to NIOSH for certification. The test includes the following:
  • 20 respirator samples are tested for a full evaluation.
  • First three samples are tested to 200 mg NaCl loading.
  • Remaining 17 samples are tested based on characteristics determined from first three load tests.
Additionally Kinectrics also provides Inhalation/Exhalation Resistance Testing:
  • TEB-APR-STP-0003 Determination of Exhalation Resistance Test, Air-Purifying Respirators
  • TEB-APR-STP-0007Determination of Inhalation Resistance Test, Air-Purifying Respirators
  • Similar to differential pressure in ASTM.
  • Fully-formed respirator is tested mounted to an anthropometric headform.
  • Airflow 85 liters per minute.
  • Maximum allowable resistances:
    • 25 mmH2O for exhalation; 35 mmH2O for inhalation.
