CBRN Respirator Standards Development – Full Facepiece Air-Purifying Respirators

Determination of Laboratory Respirator Protection Level (LRPL) Quantitative, Medium Flow, Deep Probe, Corn Oil, Fit Factor Performance Test For Chemical, Biological, Radiological, and Nuclear (CBRN) Full Facepiece Respiratory Protective Devices (RPDs) Standard Testing Procedure (STP)

May 30, 2003

PURPOSE

The test establishes procedures for ensuring a specific level of respiratory protection provided by Chemical, Biological, Radiological, and Nuclear (CBRN) Full Facepeice Respiratory Protective Devices (RPDs) requirements meet the minimum certification standards set forth in this Standard Test Procedure (STP) as prescribed in 42 CFR, Part 84, Subpart G, Section 84.63(a)(c)&(d); Federal Register, Volume 60, Number 110, June 8, 1995 after being submitted as a new approval application, extension of approval application, or examined during certified product audits.

The scope of this STP is to describe the test conditions and procedures necessary to test and certify civilian manufacturer submitted CBRN Full Facepiece RPD certification applications for NIOSH approval. A CBRN Full Facepiece RPD being a complete tight-fitting or loose-fitting, full facepiece respirator, properly outfitted with NIOSH recognized manufacturer unique components and a compatible negative pressure air-filtering device or supplied-air cylinder that is installed per the manufacturer’s current user instructions. The STP is used to test candidate CBRN RPD against corn oil aerosol while worn by a human test subject breathing in a dynamic eleven exercise specific sequence. Aerosol quantified instrumentation is remotely sensing internal and external corn oil concentrations via the attachment of tubing to a specific oral/nasal probe mounted in the tested RPD. The requirements for this STP are to ensure that all CBRN RPD, granted NIOSH CBRN approval, have:

Approvals: 1st Level, 2nd Level, and 3rd Level
