32、 for Fire RetardantTreated Wood and Fire-Retardant Coatings for Building Materials 2018 Edition This edition of NFPA 703, Standard for Fire-RetardantTreated Wood and Fire-Retardant Coatings for Building Materials, was prepared by the Technical Committee on Structures, Construction, and Materials. It
33、 was issued by the Standards Council on August 1, 2017, with an effective date of August 21, 2017, and supersedes all previous editions. This edition of NFPA 703 was approved as an American National Standard on August 21, 2017. Origin and Development of NFPA 703 In 1957, the Committee on Flameproong
34、 and Preservative Treatments began to develop a standard for the ameproong of wood. It soon became clear to the committee that the re retardantcoating industry was expanding considerably and that re-retardant admixtures of plastics and other building materials required coverage in the standard. Thus
35、, in its many subsequent meetings, the committee reexamined its approach and expanded the standard to cover all re- retardant treatments. The standard was tentatively adopted at the 1960 Annual Meeting and was submitted for nal adoption at the 1961 Annual Meeting. The 1979 edition of NFPA 703, Fire
36、Retardant Impregnated Wood and Fire Retardant Coatings for Building Materials, superseded the 1961 edition. The change in title was necessary to more adequately cover the subjects included in the text of the standard. The principal changes in the 1979 edition included improved denitions for re-retar
37、dant coatings. The 1985 edition included the addition of a new chapter that listed referenced publications whose use was mandated within the standard. In the 1992 edition, the committee provided clarication in several areas dening re resistance. The 1995 edition was a reconrmation with some editoria
38、l changes. The 2000 edition reected changes in the methods by which treated wood products are evaluated. Other changes were format driven to reect the Manual of Style for NFPA Technical Committee Documents. In the 2006 edition, technical modications brought the document into agreement with the 2003/
39、2006 editions of NFPA 5000, Building Construction and Safety Code, on the topic of re retardant treated wood. Additional changes were made to the format in compliance with the latest edition of the Manual of Style for NFPA Technical Committee Documents. The changes in the 2009 edition were editorial
40、 in nature. The 2012 edition claried the use of common terms in the document, including the denition of re-retardanttreated wood. The 2015 edition revised requirements for re-retardant-treated wood and updated referenced documents. The 2018 edition claries requirements for reretardanttreated wood. R
41、equirements that appeared in denitions have been moved to other locations for compliance with the Manual of Style for NFPA Technical Committee Documents and reference documents have been updated.FIRE RETARDANTTREATED WOOD AND FIRE-RETARDANT COATINGS FOR BUILDING MATERIALS 703-2 2018 Edition Technica
