The NIOSH National Personal Protective Technology Laboratory (NPPTL) Respirator Approval Program is responsible for evaluating and approving respirators for use within U.S. workplace settings. NPPTL certifies that all respirator models meet the minimum construction, performance, and respiratory protection standards. When a respirator has been approved by NIOSH, you can be confident that the device will provide the expected level of protection, as long as a fit test determines that the respirator fits your face and you wear it correctly.

This CERT specifies the test methods for determining the tensile properties of vulcanized rubber and thermoplastic elastomers, including tensile strength, elongation, and modulus, ensuring quality and performance in flexible materials.
