Risk Based Protective Clothing Material Permeation Criteria FY09

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

Current Information can be found at: Risk Based Protective Clothing Material Permeation Criteria FY10


  • Examine existing toxicity data for selected toxic industrial chemicals (TICs) to determine ratios of acceptable dermal to inhalation doses and create detailed permeation procedures in parallel to apply criteria.

Applicable Standards

  • NFPA Protective Clothing Standards 1991, 1994, 1971, 1951
  • ASTM F739 Standard Test Method for Resistance of Protective Clothing Materials to Permeation by Liquids or Gases Under Conditions of Continuous Contact

Key Partners

  • International Personnel Protection
  • NFPA
  • TSWG
  • ASTM


  • Emergency Responders
  • Manufacturers
  • Test Laboratories

Project Scope

  • Determine new permeation test end points for TICs that are toxicity-based.
  • Develop uniform permeation testing parameters and procedures to increase ease and reproducibility.
  • Provide new permeation criteria and test methods to standards to lessen over design of barrier protective clothing.


  • Q1 Vote and provide input on ASTM Ballot for Cumulative Permeation Method and Complete testing of two of the six target TICs
  • Q2 Support method at ASTM Meeting, Provide Update at NFPA HazMat Meeting, and attend Navy-Marine PH Conference
  • Q3 Initiate Interlaboratory Test Program, AIHCE Roundtable Presentation, and Support method at ASTM Meeting
  • Q4 Complete Interlaboratory Program and Submit final report to TSWG


  • Manuscripts published or submitted to peer review journals (approx. 0)
  • Presentations at conferences (approx. 0)
  • Standards committee meetings & public meetings (approx. 2)
  • Final report with technical data including recommended criteria/end points and methods for permeation testing for use by the NFPA Technical Committees and ASTM F23.


  • Revisions or updates to NFPA 1994, NFPA 1971, NFPA 1991, NFPA 1951 and ASTM F739.
  • New ASTM cumulative permeation test method
