32、 Method to Evaluate Fire Performance Characteristics of Pipe Insulation 2018 Edition This edition of NFPA 274, Standard Test Method to Evaluate Fire Performance Characteristics of Pipe Insulation, was prepared by the Technical Committee on Fire Tests. It was issued by the Standards Council on Novemb
33、er 10, 2017, with an effective date of November 30, 2017, and supersedes all previous editions. This edition of NFPA 274 was approved as an American National Standard on November 30, 2017. Origin and Development of NFPA 274 NFPA 274, Test Method to Evaluate Fire Performance Characteristics of Pipe I
34、nsulation, was developed by the Technical Committee on Fire Tests to ll the need for a standard method of determining the re performance of pipe insulation materials. Other codes and standards have identied the issue of the installation of such materials in air-handling plenums. Although NFPA 274 do
35、es not prescribe pass/ fail criteria, suggested acceptance criteria are provided in Annex B for consideration by the other referencing codes and standards. The 2009 edition included a new requirement for a quantiable determination of the presence of ames at the top of the exhaust chase using thermoc
36、ouples. The 2013 edition is a reconrmation of the previous edition. The 2018 edition includes updates to the latest referenced codes and standards.TEST METHOD TO EVALUATE FIRE PERFORMANCE CHARACTERISTICS OF PIPE INSULATION 274-2 2018 Edition Technical Committee on Fire Tests Barry L.
