Chemical Warfare Agent (CWA) Simulant Project - FY 06

NOTE: This page is archived for historical purposes and is no longer being maintained or updated.
Current Information can be found at: Chemical Warfare Agent (CWA) Simulant Project - FY 07


  • Provide stakeholders with a method to estimate the permeation resistance of PPE material to HD and GB agents using liquid simulant chemicals

Applicable Standards

  • ASTM F 739
  • Goal: Have newly developed test method become an ASTM standard or a subset of ASTM F 739

Key Partners

  • U.S. Army Research, Development and Engineering Command
    • Edgewood Chemical Biological Center; APG, MD
    • Natick Soldier Center; Natick, MA
  • National Institute for Standards and Technology


  • International Safety Equipment Association
  • Personal Protective Equipment Manufacturers
  • National Fire Protection Association

Project Scope

  • (Phase I) Identify simulants and laboratory procedures that can be used by manufacturers for estimating CWA permeation through barrier materials used in PPE
  • Determine the quantitative relationship between permeation behavior observed using a flooded surface (new cell) and that of traditional lower load, liquid drop challenge (5-10 g/m2) (Phase II)
  • Develop the capability to estimate barrier properties of a polymer compound based on readily available chemical and physical properties of the polymer and the permeating molecule (Phase II)
  • Develop a Prediction Matrix to determine barrier material permeation performance for CWA based on chemical and physical properties (Phase II)


  • Selected 2 other barrier materials for Phase II Testing
  • Performed Preliminary Permeation Testing with Simulants


  • Developed New Test Cell and a Test Method (Phase I)
  • Identified Four Simulants (Phase I)


  • Manuscript; D. Rivin, R.S. Lindsay, W.J. Shuely, A. Rodriguez, Liquid permeation through nonporous barrier materials, Journal of Membrane Science 246 (2005) 39-47.
  • Wrote a Draft NIOSH document (Under Peer Review) entitled, "Estimating Permeation Resistance of Nonporous Barrier Polymers to Sulfur Mustard (HD) and Sarin (GB) Chemical Warfare Agents Using Liquid Simulants"
