				Standard Respirator Testing Procedures						Print
																Related Pages
					Each respirator submitted to NIOSH for approval must meet the applicable requirements outlined in 42 CFR Part 84. Submissions must contain data that demonstrates each respirator under evaluation meets or exceeds the performance requirements. Once approved, NIOSH approval holders must continue to follow the strict quality assurance requirements specified in Subpart E. Quality control plans ensure the material and performance level of approved products continue to meet NIOSH’s requirements.
To verify respirators provide the expected level of protection for users, NIOSH uses Standard Testing Procedures. Below are the Standard Testing Procedures NIOSH uses to evaluate respirators as appropriate by the type of respirator. Accordingly, some procedures may appear in more than one category.**Standard Testing Procedures**Air-Purifying Respirators
