Improvement and Comparison of Protective Ensemble Integrity Tests - FY07

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


  • Refine the Inward Leakage Test (SF6), Man-In-Simulant-Test (MIST) and Particle Inward Leakage Test to ensure consistent evaluation and certification of protective ensembles and to provide tools for industry to aid in the development of new product technologies and designs.
Test subjects

Applicable Standards

  • NFPA Protective Clothing Standards - 1991, 1994, 1971, 1951
  • ASTM F23.20 - WK8001 Proposed - Standard Test Method for Man-In-Simulant Test (MIST) for Protective Ensembles

Key Partners

  • None


  • Emergency Responders
  • Test Laboratories
  • Manufacturers

Project Scope

  • Improvement of protective ensemble integrity tests by reducing variability that affects the precision and accuracy of the test methods as they are implemented into NFPA performance based standards.


  • FY07 - Conduct external project peer-review.
  • FY07 - Identification of sources of variability in each test.
  • FY08 - Evaluation of the SF6, MIST, and aerosol/particulate ensemble testing protocols for representative first responder protective ensembles.
  • FY09 - Management of a program to compare the three tests. Round robin testing will be conducted to compare inward leakage and protection factor values to ensure criteria are appropriate.
  • FY09 - Complete final report.


  • Final report with recommended test procedures for use by the NFPA Technical Committees and ASTM F23.
  • Submission of manuscript to a conference or journal.


  • Revisions or updates to all applicable NFPA Standards and the ASTM Test Method.
