"Standard Test Procedure (STP): Determination of Communication Performance Test for Speech Conveyance and Intelligibility: Chemical, Biological, Radiological, and Nuclear (CBRN) Full-Facepiece Air-Purifying Respirator (APR)"

This test establishes the procedures for ensuring that the level of speech conveyance and intelligibility provided by the Communication Performance Test on Chemical Biological Radiological and Nuclear (CBRN) Full Facepiece Air-Purifying Respirator (APR) submitted for Approval, or Extension of Approval, or examined during Certified Product Audits, meet the minimum certification standards set forth in 42 CFR Part 84, Subpart G, Section 84.63(a)(c)(d) and the Statement of Standard for Chemical, Biological, Radiological and Nuclear (CBRN) Full-Facepiece Air-Purifying Respirator (APR) dated 3-7-2003. The purpose of this test is to quantify the performance of a respirator in transmitting intelligible speech of a human test subject. This is accomplished by determining a listener’s ability to comprehend single-syllable words spoken by a subject wearing the respirator. This STP describes the Communication Performance Tests for Speech Conveyance and Intelligibility of the CBRN APR in sufficient detail that a person knowledgeable in the appropriate technical field can select equipment with the necessary resolution, select the appropriate human subject test panel, conduct the test, and determine whether or not the product passes the test. The Communication Performance Test shall be performed through the use of the Intelligibility of the CBRN APR in sufficient detail that a person knowledgeable in the appropriate technical field can select equipment with the necessary resolution, select the appropriate human subject test panel, conduct the test, and determine whether or not the product passes the test. Modified Rhyme Test (MRT) to evaluate a listener’s ability to comprehend single words from a speaker. Both listeners and speakers shall be in combinations of masked and unmasked postures during the MRT to provide an indication of speech transmission and intelligibility This test is considered a human factors test that requires participation of 8 test subjects to quantify the performance rating of a respirator to transmit intelligible speech.

"Standard Test Procedure (STP): Determination of Laboratory Respirator Protection Level (LRPL) Values for CBRN Air-Purifying Escape Respirator (APER)"

This test establishes the procedure for ensuring that the respirator is designed and constructed to fit persons with various facial and neck shapes and sizes as specified by the Los Alamos National Laboratory (LANL) panel. The is accomplished by determining the LRPL values provided by APER configurations submitted for new approval, extension of approval or examined during certified product audits, meet the minimum certification standards set forth in this Standard Test Procedure as prescribed in 42 CFR Part 84, Subpart G, Section 84.63(a),(c)&(d), and the Statement of Standard for Chemical, Biological, Radiological and Nuclear (CBRN) Air-Purifying Escape Respirator (APER). This STP describes the determination of LRPL for human subjects wearing a CBRN 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 respirator passes the specified test.

"Determination of Laboratory Respiratory Protection Level (LRPL) Values for CBRN Loose-Fitting Powered Air-Purifying Respirator (PAPR), Standard Testing Procedure (STP)"

This document establishes the procedure for ensuring that the respirator is designed and constructed to fit persons with various facial shapes and sizes using the NIOSH Bivariate Panel (referred to as the NIOSH Panel). This is accomplished by determining the respiratory protection level (LRPL) values provided by a powered air-purifying respirator (PAPR), loose-fitting facepiece configurations. These configurations submitted for new approval or extension of approval must meet the minimum certification standards set forth in this Standard Test Procedure (STP) as prescribed in 42 CFR Part 84 and the Statement of Standard for Chemical, Biological, Radiological and Nuclear (CBRN) Powered Air-Purifying Respirator (PAPR). This STP describes the determination of laboratory respirator protection level (LRPL) for human subjects wearing a CBRN PAPR  loose-fitting facepiece 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 respirator passes the specified test.
