NFPA 90B Standardforthe InstallationofWarmAirHeatingandAir-ConditioningSystems 2015Edition This edition of NFPA 90B, Stan
30、dard for the Installation of Warm Air Heating and Air- Conditioning Systems, was prepared by the Technical Committee on Air Conditioning. 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 90B w
31、as approved as an American National Standard on May 19, 2014. OriginandDevelopmentofNFPA90B This standard dates from 1899, when committee attention was first given to blower and exhaust systems. Prior to 1936, the subject of air conditioning was covered in NFPA standards on blower systems. In 1937,
32、it was decided to prepare a separate standard on air-conditioning, warm air heating, and ventilating systems. This standard was initially adopted in 1937 with subsequent amendments in 1938, 1939, 1940, 1942, 1950, 1952, 1955, 1956, 1960, 1961, 1963, 1964, 1965, 1968, 1971, 1973, 1976, 1980, 1984, an
33、d 1989. The 1993 and 1996 editions were reconfirmations of the 1989 edition. The 1999 edition contained changes that were mainly editorial in nature. The 2002 edition incorporated format changes to comply with theManualofStyleforNFPA Technical Committee Documents and new provisions for the removal o
34、f accessible abandoned materials in concealed spaces and plenums. The only changes to the 2006 edition were to update “flame spread rating” to “flame spread index.” The major change in the 2009 edition was to replace the references to NFPA 255 with ANSI/UL 723 and ASTM E 84, since NFPA 255 had been
35、withdrawn. All three test standards are quite similar. The changes in the 2012 edition were for the purpose of updating the editions of the referenced standards. For the 2015 edition, the changes that have been made consist of primarily editorial alterations, reference updates, and clarifications of
36、 existing language. A section and test method for air dispersion systems has also been added. 90B1 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.TechnicalCommitteeonAirConditioning RalphD.Gerdes, Chair
