"Standard Test Procedure (STP): Determination of Particulate Filter Penetration: Powered Air-Purifying Respirators (PAPR)"

This test establishes the procedure for ensuring that the level of protection provided by powered air-purifying respirator filters submitted for Approval, or examined during Certified Product Audits, meet the filter penetration requirements set forth in 42 CFR, Part 84, Subpart G, Section 84.63(a)(c)(d) and Subpart KK, Section 84.1151(a)(c), except that flow requirements of Section 84.1151(a)(c) are not used. In their place, flow requirements specified in Section 84.1156(c)(2) are applied. This is done in order that PAPR filters are tested, to the extent possible, at the minimum required air flow rate of the PAPR. This STP describes the Determination of Particulate Filter Penetration Test, Powered Air-purifying Respirator Filters Test in sufficient detail that a person knowledgeable in the appropriate technical field can select equipment with the necessary resolution, conduct the test, and determine whether or not the product passes the test.
