NFPA 1975

About this Specification

NFPA 1975 is used for the design, performance, testing and certification of nonprimary base materials used in work apparel. There are optional tests and requirements for flame resistance, odor resistance, water resistance, and insect repellency.

Compliance with NFPA 1975 requires third-party certification. ArcWear and SEI partner to quickly and accurately perform testing and issue third-party certifications under our FlashCert services.
