18、es, and guides (“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 and any Errata

Note that the commentary is not p

31、art of the standard and there-fore is not enforceable.BK-NFPA-25HB17-160347-FM.indd 10 04/11/16 11:21 AMT-1NFPA 25 SUMMARY OF TECHNICAL CHANGES: 2017This table provides an overview of major code changes from the 2014 to the 2017 edition of NFPA 25, Standard for the Inspection, Testing, and Maintenan

32、ce of Water-Based Fire Protection Sys-tems. Purely editorial and formatting changes are not included. For more information about the reasons for each change, visit www.nfpa.org/25. The first revision (FR) and second revision (SR) numbers are given in the third column of this table for reference to t

33、he official documentation of the technical committees actions.Section NumberComments FR/SR Reference1.1.5 Revised to address the fact that the standard does not typically apply to NFPA 13D systems; however, Chapter 16 was added last cycle to specifically handle these systems in very specific occupan

34、cies.FR 13.3.25 Reference to “repairs” has been removed from the definition of maintenance. Although the term maintenance is broadly defined as including repair, nowhere in the standard is maintenance used in such a fashion. Repair is expressly identified as an individual action throughout the stand

35、ard.FR 693.6.2 Revised to include additional definitions and to make current ones correlate better with NFPA 20.FR 774.1.1.2.1 A.4.1.1.2.1 Added paragraphs to specify that the owner should be aware of any potential drainage concerns that need to be considered when conducting ITM activities, and he/s

36、he should discuss these concerns with the ITM service provider prior to conducting testing activities involving the discharge of water.SR 54.1.5.1 Revised for clarity and to require corrections any time a deficiency or impairment is identified, as opposed to the assumption that it applies only when

37、found during an inspection.SR 44.1.6.2 Added items (5) and (6) to the list of factors that should be included in the evaluation required by 4.1.6. Both changes to storage and water supplies can have major implications on the adequacy of a fire protection system.FR 96, SR 524.1.10 Added to ensure tha

38、t details of the antifreeze solution be posted at the antifreeze loop main valve, so that all parties can be aware of what is on hand within a system.FR 744.6.1.14.6.1.2Added to ensure that testing of components in a system is observed at least once every three years, whether it is automated or done

39、 manually.SR 554.6.6 Added to provide requirements for automated inspection and testing. FR 98, SR 534.7 Revised to accommodate a qualitative performance-based ITM program. FR 974.8 Reference to “repairs” has been removed from this requirement. Although the term maintenance is broadly defined as inc

40、luding repair, nowhere in the standard is maintenance used in such a fashion. Repair is expressly identified as an individual action throughout the standard.FR 70BK-NFPA-25HB17-160347-2017 tables.indd 1 03/11/16 7:59 PM2017 NFPA 25 Handbook: ITM of Water-Based Fire Protection SystemsNFPA 25 Summary

42、activities for this equipment.FR 565.2.1.1.1A.5.2.1.1.1 Deleted previously included sections that were redundant. Provided clarification and guidance for assessing sprinklers showing signs of corrosion or loading. Included guidance for addressing situations where multiple, unwanted sprinkler operati

43、ons have occurred in a facility. Added annex paragraph to provide information and guidance regarding the potential loss of color in glass bulb heat responsive elements in field installation environments.FR 565.2.1.1.55.2.1.1.5.1 Revised to require that sprinklers with missing escutcheons and coverpl

44、ates either be replaced with their listed escutcheon or coverplate or replace the entire sprinkler. FR 4, SR 115.2.2.1 Deleted “in good condition” to make the requirement more specific and enforceable. FR 1005.2.3 Revised to use the more generic term braces instead of the more specific term seismic

45、braces. SR 65.2.5 Revised to bring the inspection requirements for the various signs into conformance with each other. SR 125.2.9 Added new section adapted from NFPA 13. FR 755.3.2 Revised to correlate with the automated testing revisions made in Section 4.6. SR 565.3.3 The revision reconfirms the c

46、ommittees position originating from Tentative Interim Amendment 25-11-4 (TIA 1068) issued by the Standards Council on August 9, 2012 but offers further editorial revision to present the various requirements and antifreeze concentrations in a different order, to provide better clarity.FR 76SR 145.4.1

47、.2.2 Added to correlate with NFPA 13. FR 4, SR 10Table 5.5.1 Revised to correlate with NFPA 13. FR 9Table 6.1.1.2 Reference to testing for hose storage devices has been deleted from the table. FR 27, SR 58, SR 646.1.2 Revised by moving requirements previously in table format to text. FR 646.1.3 Revi

48、sed to use the term common components. Each of the specific system chapters has been reformatted to use this term to provide consistent terminology when referring the user to Chapter 13 for ITM activities for this equipment.FR 576.2.3 6.2.4 6.2.5 6.2.6 6.2.7 6.2.8 Each of these sections is a result

49、of removing Table 6.1.2 by converting these requirements to text. This also creates consistency in the format of various chapters that do not use tables as the primary method of establishing requirements.FR 656.3.1 Revised to reinstate the requirement for testing for Class II standpipe systems.
