Head and Face Anthropometric Survey of Respirator Users, 3D Head Form

Project Scope

  • Develop an anthropometric survey detailing the face size distributions of respirator users using both traditional measurement methods and three-dimensional (3-D) scanning systems
  • Investigate the extent to which facial features can predict industrial respirator fit and protection
  • Develop respirator fit test panels using the traditional bivariate approach and the principal component analysis (PCA)
  • Develop test headforms


  • Q1 Support NAS review of respirator fit test panel
  • Q2 Complete data collection on study to correlate 3-D data to fit
  • Q2 Complete analysis of Chinese anthropometric data
  • Q3 Develop action plan for addressing IOM report
  • Q4 Develop headforms based on new sizing systems


  • Manuscripts published or submitted to peer review journals (approx. 5)
  • Presentations to stakeholders or conferences (approx. 9)
  • Standards committee meetings & public meetings (approx.10)


  • The techniques and methods developed in this study will result in the ability of manufacturers to design respirators with improved face-fitting characteristics
  • Fit Test Panel incorporated in respirator testing and certification
