Certifications
Fire-rated gypsum wall systems are certified through a rigorous testing and approval process conducted by manufacturers to ensure they meet established safety standards. The process typically begins with the development of the wall system, which includes the gypsum board, framing, and other components like insulation. The manufacturer submits the wall assembly to an accredited third-party laboratory, where it undergoes fire resistance testing based on standards such as SABS ,ASTM E119 or UL 263. During these tests, the assembly is exposed to high temperatures to evaluate its ability to contain fire and prevent it from spreading for a specified period, usually measured in hours.
Once the system successfully passes the testing criteria, the manufacturer is granted a certification or listing, which includes detailed specifications on the construction, installation, and performance characteristics of the wall system. This certification is essential for code compliance in construction projects and ensures that the fire-rated gypsum wall system can be reliably used in building applications requiring fire resistance. The certification process also involves ongoing quality control measures, where the manufacturer must regularly test production samples and maintain compliance with the standards to retain their certification.
