"Standard Test Procedure (STP): Determination of Full-Facepiece, Tight-Fitting, Negative-Pressure, Air-Purifying Respirator (APR) Performance During Dynamic Testing Against Chemical Agent Distilled Sulfur Mustard (HD) Vapor And Liquid"

This document establishes the procedures for ensuring the level of respiratory protection provided by chemical, biological, radiological, and nuclear (CBRN) protection requirements for full facepiece, tight fitting, negative pressure, P100, CBRN Capacity X, air-purifying respirator (APR) submitted for approval, extension of approval, or examined during certification product audits, meet the minimum certification standards set forth in Title 42 CFR, Part 84, Subpart G, Section 84.63(a)(c)(d) and Federal Register, Volume 60, Number 110, June 8, 1995. This STP describes a test titled “Determination Of Full Facepiece, Tight Fitting, Negative Pressure, Air-Purifying Respirator (APR) Performance During Dynamic Testing Against Chemical Agent Distilled Sulfur Mustard (HD) Vapor And Distilled Sulfur Mustard (HD) Liquid” in sufficient detail that a team of persons 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. The purpose of this standard test procedure (STP) is to describe the test conditions and procedures necessary to test and certify CBRN APR certification applications. A CBRN APR is a complete tight fitting and full face blank, properly outfitted with manufacturer unique components and a properly designed manufacturer specified APR canister that is installed per the manufacturer’s installation requirements outlined in current user instructions. This procedure is used to test CBRN APR systems against distilled sulfur mustard (HD) vapor and liquid physical states, while the respirator is operated in dynamic mode by means of a breather pump connected to the breathing zone of a manikin headform. Instrumentation is integrated under this static chamber platform for the purpose of generating and controlling challenge concentrations and detecting precise agent permeation and penetration of a tested respirator. This procedure is a separate test under the NIOSH NPPTL Respirator Branch, Certification, Evaluation and Testing Section (CET) heading of CET-APRS-STP-CBRN-0351 for challenge of sulfur mustard (HD) vapor and liquid. This procedure is designed to rigorously test the evaluated respirator as a dynamic breathing system and generate repeatable independent pass or fail results under laboratory conditions.
