Advanced Headform Total Inward Leakage Test System FY12

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


  • Develop and validate a total inward leakage (TIL) test system using headforms that have human-like characteristics and movements.

Advanced headform models

Applicable Standards

  • 42 CFR 84
  • ISO TC94 SC 15

Key Partners

  • AFRL (funding)
  • BARDA (Funding)
  • Hanson Robotics, Inc.


  • ISO
  • Respirator Manufacturers
  • Respirator Users

Project Scope

  • Define objectives and optimal characteristics for a novel headform TIL test system
  • Design and construct the test system
  • Compare fit factors between manikins and human test subjects


  • Q1 Obtained static headform
  • Q2 Complete medium static headform benchmark testing
  • Q3 Obtain IRB approval on test protocol. Complete benchmark testing on articulated headform
  • Q4 Complete Phase 1 fit testing (subjects vs. static headform)


  • Manuscript published or submitted to peer-reviewed journals (0)
  • Presentations to stakeholders or conferences (0)
  • Standards committee meetings & public meetings (0)


  • Project outputs will be used by ISO, ANSI, FDA, and NIOSH in the development of new standards
  • Other researchers utilize the project outputs to initiate new research related to TIL testing
