NFPA 252 Standard Methods of Fire Tests of Door Assemblies 2017 Edition This edition of NFPA 252, Standard Methods of Fire Tests of Door Assemblies, was prepared by the Technical Co
12、mmittee on Fire Tests. It was issued by the Standards Council on November 11, 2016, with an effective date of December 1, 2016, and supersedes all previous editions. This edition of NFPA 252 was approved as an American National Standard on December 1, 2016. Origin and Development of NFPA 252 The Ame
13、rican Society of Testing and Materials (ASTM) adopted Standard Methods of Fire Tests of Door Assemblies as a tentative standard in 1940 and as a formal standard in 1941. In 1942, the standard was adopted by the NFPA and approved by the American Standards Association. It was reconrmed and adopted in
14、1950 by the Committee on Fire Tests of Building Construction and Materials. In 1953, a new NFPA Committee on Fire Tests was formed by action of the Board of Directors, and recommendations for revision of the standard made by that committee were adopted in 1958, 1969, 1972, 1976, 1979, 1984, and 1990
15、. The basic procedure covered by this standard was developed by Underwriters Laboratories Inc. and has not undergone any signicant revisions to the original concept. The 1995 edition introduced a new provision addressing the neutral plane of the furnace. That provision permits the testing agency to
16、establish the neutral plane of the test furnace to the specication of the particular need by conducting the test under either positive pressure or atmospheric pressure. The 1999 edition of NFPA 252 contained further editorial renements to harmonize the procedures and terminology with those found in
17、NFPA 251, Standard Methods of Tests of Fire Resistance of Building Construction and Materials; NFPA 257, Standard on Fire Test for Window and Glass Block Assemblies; and NFPA 80, Standard for Fire Doors and Fire Windows. The 1999 edition also provided greater clarication for the hose stream applicat
18、ion and procedure and the application and reporting of positive pressure testing for door assemblies. For the 2003 edition, the chapter layout of NFPA 252 was reorganized to meet the Manual of Style for NFPA Technical Committee Documents, with minor editorial revisions. Revisions for the 2008 editio
19、n included tighter tolerances for furnace control and the replacement of the detailed hose stream test procedures with a reference to ASTM E2226, Standard Practice for Application of Hose Stream. Revisions to the requirements for furnace pressure and temperatures were made in the 2012 edition. The 2
20、017 edition includes new guidance on calculating pressure gradients.FIRE TESTS OF DOOR ASSEMBLIES 252-2 2017 Edition Technical Committee on Fire Tests Barry L.
