WORKING DRAFT 9.15.92—Performance Evaluation of DM and DFM Filter Respirators

5—Introduction to respirator-performance evaluations, APF determinations, and use of APFs.

  The accepted standards of professional practice for respirator-performance evaluations have evolved slowly since the early research efforts of the U.S. Public Health Service and U.S. Bureau of Mines in the 1920s.[1] Part of this evolution over the last three decades first involved efforts to quantitatively evaluate respirator performance.[2][3][4][5][6][7][8][9][10]
  These early research efforts were then followed by the determination and use of APFs for respirator selection. In order to understand the complex technical and policy issues associated with this performance-evaluation evolution, it is useful to examine the process elements involved in evaluating respirator performance and
