Standard Respirator Testing Procedures

Guidance for Standard Test Procedures used by NIOSH for Air-Purifying, Air-Supplied and Closed-Circuit Respirators.


Issued by: Centers for Disease Control and Prevention (CDC)

Standard Respirator Testing Procedures

Title 42 Code of Federal Regulations, Part 84 requires that respirators submitted for evaluation against the terms of the Standard must be accompanied by data that demonstrate the respirator under evaluation meets or exceeds the performance requirements set forth therein. Once approved, the quality assurance requirements specified in Subpart E of the Standard require an ongoing effort by the approval holder for the purpose of assuring not only the material aspects, but the performance level of the approved product.

To facilitate both of these activities, the Standard Test Procedures used by NIOSH NPPTL are posted here according to the following categories. Accordingly, some procedures may be listed in more than one category.
