19、PA1911Standard for theInspection, Maintenance, Testing, and Retirement of In-ServiceAutomotive Fire Apparatus2012 EditionThis edition of NFPA 1911, Standard for the Inspection, Maintenance, Testing, and Retirement ofIn-Service Automotive Fire Apparatus, was prepared by the Technical Committee on Fir

20、e Depart-ment Apparatus. It was issued by the Standards Council on December 13, 2011, with aneffective date of January 2, 2012, and supersedes all previous editions.This edition of NFPA 1911 was approved as an American National Standard on January 2, 2012.Origin and Development of NFPA 1911The 2007

21、edition of NFPA 1911, Standard for the Inspection, Maintenance, Testing, andRetirement of In-Service Automotive Fire Apparatus, combined three standards into a singledocument: NFPA 1911, Standard for Service Tests of Fire Pump Systems on Fire Apparatus;NFPA 1914, Standard for Testing Fire Department

22、 Aerial Devices; and NFPA 1915, Standard forFire Apparatus Preventive Maintenance Program. A chapter was added on the retirement offire apparatus. The out-of-service criteria in NFPA 1915 were reevaluated to define someconditions that require a fire apparatus to be taken out of service immediately a

23、nd someconditions that a technician needs to evaluate on a case-by-case basis to determine if theapparatus is safe for continued use. The term service test was changed to performance test,and new testing requirements were added for the apparatus chassis, low-voltage electricalsystem, foam proportion

24、ing system, compressed airfoam system, line voltage electricalsystem, and breathing aircompressor system.The 2012 edition of this standard is a general update and review of the document withminor editorial clarifications.History of NFPA 1911The first edition of NFPA 1911 was issued in 1987 and was t

25、itled Standard on Acceptance andService Tests of Fire Department Pumping Apparatus. It incorporated much of the material for-merly included in the pamphlet Fire Department Pumper Tests and Fire Stream Tables, published bythe National Board of Fire Underwriters and later by the Insurance Services Off

26、ice.In 1991, the requirements for the testing of fire pumps on new fire apparatus were transferredto the standards for new fire apparatus. Material previously referenced from other documents wasadded to make this document self-contained. The requirements were changed to include pumpsof 250 gpm (1000

27、 L/min) and larger capacity rated at 150 psi (1000 kPa).The 1997 edition expanded the tables to include data for pumps to 3000 gpm (12,000 L/min),added accuracy requirements for flow and speed measuring equipment, and required a tank-to-pump flow-rate check. The name of the standard was changed to S

28、tandard for Service Tests of FirePump Systems on Fire Apparatus to reflect that components of the pumping system, such as thetank-to-pump piping, were being checked.The 2002 edition added requirements for testing the priming device, the intake reliefvalve system, and, for pumps rated at 750 gpm (300

29、0 L/min) or more, the pumping engineoverload capability.History of NFPA 1914The first edition of NFPA 1914 dates to 1954, when the Fire Department EquipmentCommittee presented a document titled Standard Procedure for Aerial Ladder Testing, which wasdesignated as NFPA 193 for tentative adoption. In 1

30、955, it received final adoption. The docu-ment contained separate tests for wood and metal aerial ladders.19111NFPA and National Fire Protection Association are registered trademarks of the National Fire Protection Association, Quincy, Massachusetts 02169.In 1958, material covering the use, maintena

31、nce, and testing of in-service ground ladders was added to the docu-ment, and a single procedure for testing both wood and metal aerial ladders was approved. The 1959 edition addedrequirements for new aluminum ground ladders for fire department use. The 1972 edition introduced tests forevaluating pl

32、atforms.In 1975, NFPA 193 was separated into two documents, one for aerial ladders and the other for ground ladders. The newRecommended Practice for the Maintenance, Care, Testing, and Use of Fire Department Aerial Ladders and Elevating Platforms wasdesignated as NFPA 1904. The ground ladders were c

33、overed in NFPA 1931, Standard on Fire Department Ground Ladders.A complete revision in 1980 changed the document to a standard and renamed it Standard for Testing Fire DepartmentAerial Ladders and Elevating Platforms. In 1988, more details on required inspections were included and requirementsfor no

34、ndestructive testing of critical components and the testing of water towers were added. The document wasrenumbered and renamed NFPA 1914, Standard for Testing Fire Department Aerial Devices.The 1991 edition added clarification to the acceptance criteria for weld and other nondestructive testing insp

35、ec-tions, revised the requirements for water system tests, and included required testing of additional components of theaerial devices. The 1997 edition added text to provide repair recommendations when the manufacturer is no longer inbusiness, required that free weights be used in testing, allowed

36、for acoustic emission testing, added requirements fortesting secondary operating controls, and added a suggested form for recording the inspection and test results.The 2002 edition revised the qualifications for testing personnel, added additional requirements for the inspectionand testing of tracto

37、r-drawn components, and more clearly delineated when nondestructive testing is required inaddition to the inspections, operational tests, and load tests.History of NFPA 1915The National Transportation Safety Board (NTSB) report “Special Investigation ReportEmergency Fire Appara-tus,” adopted March 1

38、9, 1991, raised concerns about the quality and type of service and repair being done on fireapparatus. Subsequent inquiries from the Federal Department of Transportation (DOT) about the different types,uses, and weights of apparatus and how they are maintained prompted the International Association

39、of Fire Chiefs(IAFC) Apparatus Maintenance Section to petition NFPA to write a preventive maintenance standard for fire appara-tus. While NFPA 1500, Standard on Fire Department Occupational Safety and Health Program, requires fire departments toestablish a preventive maintenance program for their ap

40、paratus and equipment, there was no standard for such aprogram.The first edition of NFPA 1915, Standard for Fire Apparatus Preventive Maintenance Program, was issued in 2000 toestablish the minimum requirements for a preventive maintenance program for fire apparatus. These requirementswere designed

41、to improve the safety and reliability of fire apparatus and support the requirements in other NFPAstandards related to emergency vehicle maintenance programs.19112 INSPECTION, MAINTENANCE, TESTING, AND RETIREMENT OF IN-SERVICE AUTOMOTIVE FIRE APPARATUS2012 EditionTechnical Committee on Fire Departme
