29、7A Standardfor WetChemicalExtinguishingSystems 2013Edition This edition of NFPA 17A, Standard for Wet Chemical Extinguishing Systems, was prepared by the Technical Committee on Dry and Wet Chemical Extinguishing Systems. It was issued by the Standards Council on November 27, 2012, with an effective
30、date of December 17, 2012, and supersedes all previous editions. This edition of NFPA 17A was approved as an American National Standard on December 17, 2012. OriginandDevelopmentofNFPA17A On April 6, 1983, the Standards Council received a request to assign the subject of wet chemical extinguishing s
31、ystems to the appropriate committee. Listed systems had been avail- able for some time. After the Foam Committee declined the request, the Dry Chemical Extin- guishing Systems Committee, which had been activated in 1952, was asked to assume respon- sibility for the project. In May 1983, that committ
32、ee voted to accept the assignment and requested that the Standards Council expand the Committee Scope to include the new topic. The Committee also requested that the new document be identified as NFPA 17A,Standardfor Wet Chemical Extinguishing Systems. A subcommittee met in June 1983 to develop the
33、text. In November 1984, the Council approved a request to change the name of the Committee to the Committee on Dry and Wet Chemical Extinguishing Systems. The first edition of NFPA 17A was in 1986; the 1990 edition was a partial revision of the 1986 edition. The 1994 edition was rewritten to more cl
34、early state the requirements and to separate the mandatory requirements from the nonmandatory recommendations to assist in making the document more usable, enforceable, and adoptable. The 1998 edition of this standard was revised to clarify the requirements for protection of unclosable openings and
35、equipment shutdown. The changes to the 2002 edition consisted of an editorial reformatting of the standard to comply with the Manual of Style for NFPA Technical Committee Documents. Technical changes included clarification of requirements for fuel and power shutoff upon actuation of the system and r
36、ewriting the requirement for simultaneous systems operation. Changes to the 2009 edition clarified inspection, maintenance, and service requirements and qualifications for service personnel. Revisions to the 2013 edition of this standard clarify requirements for inspection and maintenance and add ne
37、w requirements for installation acceptance. 17A1 NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.TechnicalCommitteeonDryandWetChemicalExtinguishingSystems DavidA.deVries, Chair Firetech Engineering Inc.,
