NIOSH Updates Standard Testing Procedure for PAPRs with Hoods or Helmets

NIOSH has updated the standard testing procedure for the determination of the noise level test for powered air-purifying respirators with hoods or helmets. The purpose of the update is to establish the procedure for ensuring that operational noise levels of PAPRs submitted to the agency for approval or extension of approval do not exceed established maximum certification requirements. NIOSH’s procedure is intended to describe the test in sufficient detail so that a person who is knowledgeable in the appropriate technical field can select equipment with the necessary resolution, conduct the test, and determine whether a product passes the test.

A PDF copy of the revised procedure, dated May 28, 2019, is available from NIOSH’s website. More information on standard respirator testing procedures is available from the NIOSH National Personal Protective Technology Laboratory.
