29、Reserved.NFPA25Standard for theInspection, Testing, and Maintenance of Water-Based Fire ProtectionSystems2014 EditionThis edition of NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-BasedFire Protection Systems, was prepared by the Technical Committee on Inspection, Testing, a

30、ndMaintenance of Water-Based Systems and acted on by NFPA at its June Association TechnicalMeeting held June 1013, 2013, in Chicago, IL. It was issued by the Standards Council onAugust 1, 2013, with an effective date of August 21, 2013, and supersedes all previous editions.This edition of NFPA 25 wa

31、s approved as an American National Standard on August 21,2013.Origin and Development of NFPA 25The first edition of NFPA 25, in 1992, was a collection of inspection, testing, and mainte-nance provisions that helped ensure the successful operation of water-based fire protectionsystems. NFPA 25 was de

32、veloped as an extension of existing documents such as NFPA 13A,Recommended Practice for the Inspection, Testing, and Maintenance of Sprinkler Systems, andNFPA 14A, Recommended Practice for the Inspection, Testing, and Maintenance of Standpipe and HoseSystems, which have successfully assisted authori

33、ties having jurisdiction and property ownerswith routine inspections of sprinkler systems and standpipes. These documents have sincebeen withdrawn from the NFPA standards system. NFPA 25 became the main document gov-erning sprinkler systems as well as related systems, including underground piping, f

34、irepumps, storage tanks, water spray systems, and foam-water sprinkler systems.This document provides instruction on how to conduct inspection, testing, and mainte-nance activities. It also stipulates how often such activities are required to be completed.Requirements are provided for impairment pro

35、cedures, notification processes, and systemrestoration. This type of information, where incorporated into a building maintenance pro-gram, enhances the demonstrated favorable experience of all water-based fire protectionsystems.The 1995 edition incorporated several improvements that reflected the in

36、itial experiencewith the standard. A new chapter was added that addressed obstructions in pipe as well asappropriate corrective actions.The 1998 edition refined testing requirements and frequencies and provided additionalguidance for preplanned impairment programs. The document scope was expanded to

37、 in-clude marine systems.The 2002 edition continued to refine testing frequencies for waterflow devices and evalu-ation of the annual fire pump test data. This edition also included additional informationregarding evaluation and test methods for microbiologically influenced corrosion (MIC).In the 20

38、08 edition a section permitting performance-based testing was added, providingguidance on alternative means for determining testing frequencies based on system/component failure rates. Component replacement testing tables were introduced in thisedition to provide guidance for the appropriate tests t

39、o be performed following replacementof system components. Inspection, testing, and maintenance requirements for water mistsystems were extracted from NFPA 750 and were inserted into a new chapter. This actionconsolidated inspection, testing, and maintenance requirements for all water-based fire pro-

40、tection systems into one document.The 2011 edition further updated testing frequencies based on a growing database ofinspection, testing, and maintenance records. In two new annexes information was providedfor classification of needed repairs and hazard evaluation. The 2011 edition also added newdef

41、initions differentiating the levels of deficiency for determining the priority of repair.251NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.The 2014 edition of NFPA 25 has many significant changes with m

42、any specific to the chapter on fire pumps. Theoperating test requirements were rewritten to consider a baseline weekly test for all pumps with a series of exceptionsthat would allow for a modified testing frequency. New language was added to address confirmation of pressurerecordings and a new fuel

43、quality test for diesel-driven pumps.Definitions were added for the various frequencies of inspection, testing, and maintenance (ITM) tasks to create a“window” for completion of the task. The concept of internal inspection has been modified to an internal assessmentconcept, where a performance-based

44、 assessment frequency is explicitly addressed. The scope of the Technical Com-mittee on Inspection, Testing, and -Based Systems was updated to specifically address water mist systems. The watermist system was modified such that the extract tags from NFPA 750 have been removed, since the material in

45、thischapter is now in the jurisdiction of NFPA 25.A new chapter was added to address NFPA 13D systems that are installed outside of one- and two-family homes. Therequirements for inspecting antifreeze systems have been updated to include the latest information from the FireProtection Research Founda

46、tion testing on standard spray sprinklers. The table providing examples of classificationsfor deficiencies and impairments has been relocated from Annex E to Annex A and is attached to the definition ofDeficiency.252 INSPECTION, TESTING, AND MAINTENANCE OF WATER-BASED FIRE PROTECTION SYSTEMS2014 Edi
