National Institute for Occupational Safety and Health (NIOSH) specifies minimum approval requirements for respiratory protective devices in Title 42 Code of Federal Regulations (CFR) Part 84. NIOSH reviews respirator approval applications, which contain technical specifications, drawings, and other related information. NIOSH also inspects, examines and tests the respirators to determine that the applicable requirements are met for individual, completely assembled respirators, as described in §84.30(a).
