"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.
