"Standard Test Procedure (STP): Determination of Human Subject Breathing Gas (HSBG) Concentrations (Carbon Dioxide and Oxygen) for Chemical, Biological, Radiological and Nuclear (CBRN) Air-Purifying Escape Respirator"

This document describes the Human Subject Breathing Gas Concentrations for the CBRN hood type APER 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 APER passes the specified test. The procedure is a separate test under the NIOSH/NPPTL Respirator Branch heading of CET-CBRN-ESCAPE-STP-0454 for the concentration of inspired carbon dioxide gas at the mouth and the calculated average concentration during the inhalation portion of the breathing cycle. The procedure is designed to rigorously test the evaluated APER on a human test subject as a dynamic respiratory protective system and generate repeatable, independent pass or fail results under defined laboratory conditions.

"Standard Test Procedure (STP): Determining the Donning Time of Chemical, Biological, Radiological and Nuclear (CBRN) Escape Respirator (Air-Purifying or Self-Contained)"

This test establishes the procedures for determining the time to don a chemical, biological, radiological, and nuclear (CBRN) escape respirator (ER) for approval, extension of approval, or examined during certified product audits, meets the minimum certification standards set forth in this standard test procedure (STP) as prescribed by 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 the determination of donning effectiveness of the CBRN ER (air-purifying and self-contained) test in sufficient detail that a person knowledgeable in the appropriate technical field can conduct the test and determine whether or not the product meets the test requirements.

"Determination of particulate filter efficiency level against solid particulates for powered air-purifying respirators, Series PAPR100-N, standard testing procedure"

This procedure establishes the means of ensuring that the filter efficiency of PAPR100-N series filters meet the requirements set forth in 42 CFR Part 84, Subpart K, Section 84.180. These filters or filter cartridges may be integral to respirator construction; mounted individually, or in sets of up to three; used in conjunction with filter, cartridges or canisters for half-mask, full facepieces, hoods and helmets.

"Determination of low flow warning device activation for breath assist type tight-fitting powered air-purifying respirators, standard testing procedure"

This test establishes the method of ensuring that the level of protection provided by the low flow warning device requirement for breath assist type tight-fitting powered air-purifying respirators, series PAPR100, meet the minimum requirements set forth in 42 CFR Part 84, Subpart K, Section 84.171(j).

"Determination of low flow warning device activation for powered air-purifying respirators series PAPR100, standard testing procedure"

This procedure establishes the method of ensuring that the level of protection provided by the low flow warning device activation requirement for powered air-purifying respirators, series PAPR100, meet the minimum requirements set forth in 42 CFR Part 84, Subpart K, Section 84.171(j).
