    2、SCLAIMER OF LIABILITY CONCERNING THE USE OF NFPA STANDARDS NFPA codes, standards, recommended practices, and guides (“NFPA Standards”), of which the document contained herein is one, are developed through a consensus standards development process approved by the American National Standards Institute

    3、. This process brings together volunteers representing varied viewpoints and interests to achieve consensus on fire and other safety issues. While the NFPA administers the process and establishes rules to promote fairness in the development of consensus, it does not independently test, evaluate, or

    4、verify the accuracy of any information or the soundness of any judgments contained in NFPA Standards. The NFPA disclaims liability for any personal injury, property or other damages of any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting f

    5、rom the publication, use of, or reliance on NFPA Standards. The NFPA also makes no guaranty or warranty as to the accuracy or completeness of any information published herein. In issuing and making NFPA Standards available, the NFPA is not undertaking to render professional or other services for or

    6、on behalf of any person or entity. Nor is the NFPA undertaking to perform any duty owed by any person or entity to someone else. Anyone using this document should rely on his or her own independent judgment or, as appropriate, seek the advice of a competent professional in determining the exercise o

    7、f reasonable care in any given circumstances. The NFPA has no power, nor does it undertake, to police or enforce compliance with the contents of NFPA Standards. Nor does the NFPA list, certify, test, or inspect products, designs, or installations for compliance with this document. Any certification

    8、or other statement of compliance with the requirements of this document shall not be attributable to the NFPA and is solely the responsibility of the certifier or maker of the statement. REMINDER: UPDATING OF NFPA STANDARDS Users of NFPA codes, standards, recommended practices, and guides (“NFPA Sta

    9、ndards”) should be aware that NFPA Standards may be amended from time to time through the issuance of Tentative Interim Amendments or corrected by Errata. An official NFPA Standard at any point in time consists of the current edition of the document together with any Tentative Interim Amendment and

    10、any Errata then in effect. In order to determine whether an NFPA Standard has been amended through the issuance of Tentative Interim Amendments or corrected by Errata, visit the Document Information Pages on NFPAs website. The Document Information Pages provide up-to-date, document specific informat

    11、ion including any issued Tentative Interim Amendments and Errata. To access the Document Information Page for a specific NFPA Standard, go to http:/www.nfpa.org/docinfo to choose from the list of NFPA Standards or use the search feature on the right to select the NFPA Standard number (e.g., NFPA 101

    12、). In addition to posting all existing Tentative Interim Amendments and Errata, the Document Information Page also includes the option to sign-up for an “Alert” feature to receive an email notification when new updates and other information are posted regarding the document.1/14 IMPORTANT NOTICES AN

Interpretations of NFPA Standards A statement, written or oral, that is not processed in accordance with Section 6 of the Regulations Governing the Development of NFPA Standards shall not be considered the official position of NFPA or any of its C

    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

    18、sole responsibility for determining the validity of any such patent rights, as well as the risk of infringement of such rights, and the NFPA disclaims liability for the infringement of any patent resulting from the use of or reliance on NFPA Standards. NFPA adheres to the policy of the American Nati

    19、onal Standards Institute (ANSI) regarding the inclusion of patents in American National Standards (“the ANSI Patent Policy”), and hereby gives the following notice pursuant to that policy: NOTICE: The users attention is called to the possibility that compliance with an NFPA Standard may require use

    20、of an invention covered by patent rights. NFPA takes no position as to the validity of any such patent rights or as to whether such patent rights constitute or include essential patent claims under the ANSI Patent Policy. If, in connection with the ANSI Patent Policy, a patent holder has filed a sta

    21、tement of willingness to grant licenses under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, copies of such filed statements can be obtained, on request, from NFPA. For further information, contact the NFPA at the address listed

    22、 below. Law and Regulations Users of NFPA Standards should consult applicable federal, state, and local laws and regulations. NFPA does not, by the publication of its codes, standards, recommended practices, and guides, intend to urge action that is not in compliance with applicable laws, and these

    23、documents may not be construed as doing so. Copyrights NFPA Standards are copyrighted. They are made available for a wide variety of both public and private uses. These include both use, by reference, in laws and regulations, and use in private self-regulation, standardization, and the promotion of

    24、safe practices and methods.

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.
