Laws the 1973 NFPAedition on December 28, 1973; the 1974 NFPAedition on January 30, 1975; the 1975 NFPAedition on February 27, 1976; and the 1977 NFPAedition on October 18, 1977. The 1982 edition of Standard for Firesafety Criteria for Mobile Home Installatio
20、ns, Sites, and Communities superseded the 1977 edition and was adopted by NFPA at its Annual Meeting held in San Francisco on May 19, 1982. The 1982 edition was produced by the newly formed Committee for Firesafety for Mobile Homes (June 10, 1979), which was charged with the responsibility of develo
21、ping documents for fire safety criteria for single-family mobile homes, including the installation, sites, and communities, and the maintenance of and improvements for existing mobile homes. There- fore, that edition excluded all sections of previous editions not considered within the com- mittee sc
22、ope. Notably excluded were stabilizing and anchoring systems, requirements for piers and footings, and plumbing, including sewage disposal systems. Requirements for park electrical systems were addressed by reference to NFPA 70, National Electrical Code. Modifications were also made in sections deal
23、ing with fuel supply, air conditioning, and life and fire safety. Major revisions to the standard were made in the 1987 edition in an attempt to better coordinate the NFPAchapters in a joint publication with NCSBCS,ANSIA225.1/NFPA501A. Major changes included substituting “manufactured home” for “mob
24、ile home” throughout; deleting Chapter 3, “Air Conditioning”; expanding Chapter 2, “Fuel Supply”; and combining three appendixes into two. The standard was reconfirmed in 1992 with a plan to expand the scope of NFPA 501A to cover fire safety requirements for the design, construction, installation, a
25、lteration/ rehabilitation, maintenance, use, and occupancy of manufactured homes, manufactured home sites, and manufactured home communities, including accessory buildings and struc- tures. This was a major revision of the scope and the entire standard, and the committee targeted a complete revision
26、 of 501A for 1994. 501A1 Copyright National Fire Protection Association Provided by IHS under license with NFPA Not for ResaleNo reproduction or networking permitted without license from IHS -,-,- The 1997 edition was a reconfirmation of the 1992 edition of NFPA501A. The proposed expansion of the sc
27、ope of the 1992 edition, as noted in the previous paragraph, was discussed and acted on by the technical committee. The scope of the NFPA 501A document was not expanded but instead a new document was generated. This document, NFPA 501, Standard on Manufactured Housing, represents the reconstituted 1
28、977 edition of Standard for Mobile Homes. This original document was the basis for the federal Manufactured Home Construction and Safety Standards. The earlier editions of NFPA 501A were jointly developed and published by NFPA and NCSBCS as the A225.1/ NFPA 501A document. The 1997 edition of NFPA 50
29、1A was published as a separate, stand-alone document in agree- ment with NCSBCS and contained only the fire safety requirements. The nonfire safety requirements were published by NCSBCS as A225.1 (1994 edition). At present, NFPA has taken over responsibility for the NCSBCS A225 Standard. It was proc
30、essed concurrently with this edition of NFPA 501A. The 1999 edition was a reconfirmation of the earlier document. In June 1998, NFPA was selected by the U.S. Department of Housing and Urban Development to update the federal standards (24 CFR 3280) for manufactured homes.As a result of this selection
31、 by HUD, the original technical committee for manufactured homes was expanded into six technical committees and a technical correlating committee. This expansion occurred during the Report on Comments phase of the 1999 edition. The2000editionhadonlyafewminorrevisions.Onerevision,in4.3.5,pertainedtou

The 2003 edition has been reformatted to meet the NFPA Manual of Style requirements, which are editorial and format related. Several definitions were deleted during this revision cycle. 501A2FIRE SAF
