NFPA 275 Standard MethodofFireTestsfortheEvaluationofThermalBarriers 2013Edition This edition of NFPA 275, Standard Method of Fire Tests for the Evaluation of Thermal Barriers, was prepared by the Technical Committee on

26、 Fire Tests, and acted on by NFPA at its June Association Technical Meeting held June 1114, 2012, in Las Vegas, NV. It was issued by the Standards Council on August 9, 2012, with an effective date of August 29, 2012, and super- sedes all previous editions. This edition of NFPA 275 was approved as an

27、 American National Standard on August 29, 2012. OriginandDevelopmentofNFPA275 The 2009 edition was the first edition of NFPA 275, Standard Method of Fire Tests for the Evaluation of Thermal Barriers Used Over Foam Plastic Insulation. Several NFPA codes and stan- dards, as well as other model codes,

28、include provisions that require portions of buildings to be separated by 15-minute thermal barriers. Building and fire regulations have traditionally addressed thermal barriers in vague and imprecise terms. Provisions of other codes and standards indicate that thermal barriers are intended to limit

29、thermal transmission based on fire resistance testing and must remain in place based on a full-scale test. The NFPA 275 fire test methods identified specific sample construction, fire exposures, and acceptance criteria to qualify a material or product for use as a thermal barrier. It was anticipated

30、 that this test method would be referenced by other model building and fire codes and standards. The 2013 edition has been revised to address both foam plastic insulation and metal composite materials (MCM). References have been updated to reflect the most recent editions. 2751 NFPA and National Fir
