30、ion This edition of NFPA 80A, Recommended Practice for Protection of Buildings from Exterior Fire Exposures, was prepared by the Technical Committee on Exposure Fire Protection. It was issued by the Standards Council on May 13, 2016, with an effective date of June 2, 2016, and supersedes all previou

31、s editions. This edition of NFPA 80A was approved as an American National Standard on June 2, 2016. Origin and Development of NFPA 80A In 1924, the NFPA Committee on Protection of Openings in Walls and Partitions developed Suggested Practice for Protection Against Exposure of Openings in Fire-Resist

32、ive Walls to meet the demand for a method of evaluating the severity of exposure and a uniform practice for specifying protection. It was submitted as a tentative recommended practice and adopted by NFPA in 1925 as NFPA 80A. In 1930, the pamphlet was added to Standard for the Protection of Openings

33、in Walls and Partitions Against Fire as an appendix, but it was not published until the 1944 edition of the National Fire Codes , Vol. III, except as part of the “NFPA Proceedings.” It also was summarized in the 9th edition (1941) of the Handbook of Fire Protection. In 1963, the NFPA Committee on Ex

34、posure Fire Protection was formed and charged with the task of updating the 1925 edition of NFPA 80A. The committee submitted a complete revision of the 1925 text to the Association for tentative adoption in 1967 and a revision of the tentative text for ofcial adoption in 1970 with the title Recomme

35、nded Practice for Protection of Buildings from Exterior Fire Exposures. In the 1987 edition, there were substantive and editorial changes. In 1993, revisions continued to examine the effect of re on an exposed structure and calculative methods to help ensure a reduction in re impact due to exposure

36、res. In the 1996 edition, some editorial changes were made in addition to changes in the example in Appendix B. Revisions for the 2001 edition were mainly editorial to comply with the 2000 edition of the NFPA Manual of Style for technical committee documents. Language was added to recognize new tech

37、nology, such as listed window sprinklers. Revisions in the 2007 edition included a change to the denition of noncombustible material, which accomplished two objectives. First, it removed technical requirements from the denition in accordance with the Manual of Style for NFPA Technical Committee Docu

38、ments, and second, it allowed the technical committee responsible for NFPA 220, Standard on Types of Building Construction, which owns the denition, to make changes to the technical criteria if and when they deem appropriate, without having the changes “cascade” across other documents. Other changes

39、 were made to clarify the committees intent in a number of sections.PROTECTION OF BUILDINGS FROM EXTERIOR FIRE EXPOSURES 80A-2 2017 Edition Revisions in the 2012 edition included replacing the reference to NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building Materials, wh

40、ich was withdrawn in Fall 2009, with UL 723, Standard for Test for Surface Burning Characteristics of Building Materials. The denition of noncombustible material was revised to reect that it is extracted from NFPA 220, and the terms radiant heat and indexes replaced outdated terms in a number of loc

41、ations. In addition, some other minor changes were made. Revisions in the 2017 edition are minor and include updating referenced standards, deleting NFPA 220 as the source for the extracted denition of noncombustible material, and moving the second sentence of the denition for noncombustible materia
