9、Standards”) should be aware that NFPA Standards may be amended from time to time through the issuance of Tentative Interim Amendments or corrected by Errata. An official NFPA Standard at any point in time consists of the current edition of the document together with any Tentative Interim Amendment a
10、nd any Errata then in effect.In order to determine whether an NFPA Standard has been amended through the issuance of Tentative Interim Amendments or corrected by Errata, visit the Document Information Pages on NFPAs website. The Document Information Pages provide up-to-date, document specific inform
11、ation including any issued Tentative Interim Amendments and Errata.To access the Document Information Page for a specific NFPA Standard, go to http:/www.nfpa.org/docinfo to choose from the list of NFPA Standards or use the search feature on the right to select the NFPA Standard number (e.g., NFPA 10

NFPA takes no position as to the validity of any such patent rights or as to whether such patent rights constitute or include essential patent claims under the ANSI Patent Policy. If, in connection with the ANSI Patent Policy, a patent holder has filed a statement of
21、 willingness to grant licenses under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, copies of such filed statements can be obtained, on request, from NFPA.

30、 Committee on Aerosol Extinguishing Technology. It was issued by the Stan-dards Council on November 11, 2014, with an effective date of December 1, 2014, and super-sedes all previous editions.This edition of NFPA 2001 was approved as an American National Standard on December1, 2014.Origin and Develo
31、pment of NFPA 2001The Technical Committee on Halon Alternative Protection Options was organized in 1991and immediately started work to address the new total flooding clean agents that were beingdeveloped to replace Halon 1301. A need existed for an explanation of how to design, install,maintain, and
32、 operate systems using these new clean agents, and NFPA 2001 was establishedto address that need. The 1994 edition was the first edition of NFPA 2001. The standard wasrevised in 1996, 2000, and 2004.In January 2005, the technical committees responsible for NFPA 12, NFPA 12A, andNFPA 2001 were combin
33、ed into the Technical Committee on Gaseous Fire ExtinguishingSystems to better address and resolve issues among those documents. This action was in-tended to facilitate correlation and consistency as requested by the U.S. EnvironmentalProtection Agency.The 2008 edition added requirements for local a
34、pplication systems.The 2012 edition included a complete rewrite of Annex C. In addition, more informationon the environmental impact of clean agents was added to Annex A.The 2015 edition adds new content regarding recycling and disposal of clean agents andadds new system design criteria for 200 bar
35、and 300 bar IG-01 systems. A sample systemacceptance report was added to aid in conformance with commissioning practices. The com-mittee completed an update of all references and reviewed the pipe design criteria against thereferenced piping code. This edition also revises the requirements for cylin

For inert gas clean agents that employ the use of apressure-reducing device
44、, Table 4.2.1.1.1(a) shall be usedfor piping upstream of the pressure reducer, and 4.2.1.1.2shall be used to determine minimum pipe design pressurefor piping downstream of the pressure reducer. Thepressure-reducing device shall be readily identifiable. Forhalocarbon clean agents, Table 4.2.1.1.1(b)
45、shall be used. Ifdifferent fill densities, pressurization levels, or higher stor-age temperatures from those shown in Table 4.2.1.1.1(a) orTable 4.2.1.1.1(b) are approved for a given system, theminimum design pressure for the piping shall be adjustedto the maximum pressure in the agent container at
