17、ommittees and shall not be considered to be, nor be relied upon as, a Formal Interpretation. Patents The NFPA does not take any position with respect to the validity of any patent rights referenced in, related to, or asserted in connection with an NFPA Standard. The users of NFPA Standards bear the

NFPA 220 Standardon TypesofBuildingConstruction 2015Edition This edition of NFPA 220, Standard on Types of Building Construction, was prepared by the Technic
30、al Committee on Building Construction. It was issued by the Standards Council on April 29, 2014, with an effective date of May 19, 2014, and supersedes all previous editions. This edition of NFPA 220 was approved as an American National Standard on May 19, 2014. OriginandDevelopmentofNFPA220 In 1952
31、, the Committee on Building Construction secured tentative adoption of NFPA 220, Standard on Types of Building Construction, at the NFPA Annual Meeting. At the 1954 NFPA Annual Meeting, revisions of the 1952 tentative text were adopted by the Association, and in 1955 minor revisions also were acted
32、on favorably. A new definition ofnoncombustibility and editorial changes in the description of the fire resistance rating of structural members (under the definition of fire- resistive construction) were adopted at the 1956 NFPA Annual Meeting on the recommendation of the Committee on Building Const
33、ruction. In 1958, with the development of the use of plastics in building construction, recommen- dations on the types of standard fire tests to be used in evaluating the fire safety of these materials were adopted and inserted in the appendix. In 1961, an appendix was adopted to furnish a guide to
34、NFPA committees, regulatory officials, and others that addressed the classification of air-supported structures. In 1975, a more fundamental definition of noncombustible was added, including the intro- duction of a definition of the termlimited-combustible, based on potential heat value limitations
35、and more generalized definitions for types of building construction. In 1979, the standard was extensively rewritten to introduce the nomenclature related to construction Type I through Type V, which included parenthetically placed hourly fire resis- tance designations of the structural components.
36、The 1985 edition included the addition of a new Chapter 4, which provided referenced publications whose use is mandated within this standard. The 1992 and 1995 editions pro- vided changes in technical terminology as well as changes to increase the user-friendliness of the standard. The 1999 edition
37、implemented a number of relatively minor changes, including the addition of several new definitions, the addition of a new requirement pertaining to exterior nonload- bearing walls, and a new provision concerning the use of heavy timber exterior walls. In the 2006 edition, NFPA 220 became an extract
38、 document ofNFPA5000 , Section 7.2. At the request of the Standards Council, the new edition provided users with a stand-alone set of requirements for construction types and fire resistance ratings of structural elements. The 2009 edition provided updates to the extracted text that was sourced back
39、to NFPA 5000 and NFPA 90A. These revisions included updates to the test protocols used to establish flame spread/smoke developed index values, modified criteria for materials used in air handling plenum spaces, and provided recognition of the new criteria used to determine building height and grade
40、geometries. The 2012 edition was updated to reflect changes in NFPA 5000 and NFPA 90A. Revisions included updates to the requirements for plenums and noncombustible materials. The 2015 edition has been revised to include new requirements for limited and noncom- bustible materials. Referenced publica
41、tions have also been updated. 2201 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.TechnicalCommitteeonBuildingConstruction JosephH.Versteeg, Chair Versteeg Associates, CT E Rep.
