Development of PPE Ensemble Test Methods - FY12

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.


  • To develop innovative test methods for evaluating the integrity of protective clothing and ensembles against aerosol particulate challenges.
Refined Penetration Cell and Wind tunnel

Applicable Standards

  • ASTM F23
  • NFPA 1994, 1971, 1951

Key Partners

  • Washington University in St. Louis
  • NIOSH Nanotechnology Research Center (NTRC)
  • Clarkson University


  • PPE manufacturers
  • Firefighters
  • ASTM
  • NFPA
  • IAFF
  • DuPont NOSH consortium
Particle deposition on the MPAS substrate

Project Scope

  • Task 1. Optimization of the magnetic passive aerosol sampler (MPAS) design - evaluating MPAS efficiency under various conditions and interferences, and comparison with reference samplers.
  • Task 2. Development and validation of a standardized bench-scale particulate penetration test method.


  • Q1 Submitted 3 manuscripts to the journal of Aerosol Science & Technology
  • Q2 Refined penetration cell design for Task 2
  • Q3 Evaluate performance of the penetration cell under conditions of different particle sizes, various clothing materials, and different wind velocities
  • Q4 Submit a manuscript from the performance evaluation


  • Manuscripts published in peer-reviewed journals (3 published that have been cited 5 times, 1 accepted, 2 submitted, more in development)
  • Presentations at national/international conferences and stakeholder meetings (11)
  • Wash U final report on CFD modeling of the MPAS performance
  • Employee invention reports (2)
  • Book chapter (1)


  • This project has contributed to NIOSH NTRC report titled “Approaches to Safe Nanotechnology: Managing the Health and Safety Concerns Associated with Engineered Nanomaterials”
  • This project has resulted in a new project on nanoparticle penetration through protective clothing funded by NTRC (the study was completed)
  • Expected outcome is to improve standards and test methods for protective clothing used for protection against inert and biological aerosols
