We are seeking to comply with NFPA 101 126.96.36.199 Hazardous Area Protection for a new health care occupancy. There is a particular ceiling assembly we would like to use in order to stop the fire rated walls at the ceiling level. This assembly involves intumescent paint on 5/8" Type-X gypsum board and wood trusses at 24" O.C. Guardian Fire Testing Laboratories provided an Engineering Evaluation Report (EER) which states that this particular assembly qualifies as a 1-hour ceiling assembly. However, the EER references a fire test report for a similar (not identical) floor/ceiling assembly tested in accordance with ASTM E-119 and NFPA 251. In other words, the testing agency used a fire test for one assembly to interpolate a fire rating for the assembly in question. Is there any way to determine if NFPA 101 recognizes an EER from an accredited fire testing laboratory?
