WORKING DRAFT 9.15.92—Performance Evaluation of DM and DFM Filter Respirators
5

  In late 1990 the ANSI Subcommittee Z88.2 (Practices for Respiratory Protection) completed a revision of their 1980 standard, which was accepted by the Z88 Committee for Respiratory Protection.[1] Their 1991 revision has been forwarded by the ANSI Z88 Committee's Secretariat to the ANSI Board of Standards Review for their approval.[2] However, as of September 1992, a formal appeal to the ANSI Secretariat regarding the submitted revision was in the process of adjudication.[3] A successful appeal could result in changes to the APFs given in Table D of this evaluation.[4] Refer to the material titled Evaluation of the ANSI 1991 APF-Determination Strategy given later in this evaluation for an extended discussion of the 1991 ANSI 288 APFs.
