14、ASME AG-1.This Standard provides a basis for the development of test programs, in-service test procedures,and corrective action requirements.In 1971, what is now the Committee on Nuclear Air and Gas Treatment was organized as ANSIN45.8 to develop standards for high-reliability, air-cleaning equipmen
15、t for nuclear facilities andcorresponding tests to confirm performance of the equipment. Two standards, N509 and N510,were published in 1975 and 1976, and updated in 2002 and 2007, respectively. In 1976, under theaccredited organization rules, the Committee was reorganized as the ASME Committee on N
16、uclearAir and Gas Treatment. The scope of responsibility was broadened to include the developmentof codes and standards for design, fabrication, inspection, and testing of air-cleaning and condi-tioning components and appurtenances, as well as air-cleaning components used in engineeringsafety system
17、s in nuclear facilities. The current assignment is to produce code documents andmaintain ASME N509 and N510, and develop and maintain ASME N511.Suggestions for improvement gained in the use of this Standard will be welcomed. They shouldbe sent to the Secretary, Committee on Nuclear Air and Gas Treat
18、ment, The American Societyof Mechanical Engineers, Three Park Avenue, New York, NY 10016.This Standard was approved by the ASME Committee on Nuclear Air and Gas Treatment andthe ASME Board of Nuclear Codes and Standards, and was subsequently approved as an AmericanNational Standard by the American N

27、D TESTREQUIREMENTSAll inspections and tests shall be conducted in accor-dance with the requirements within this Standard andthe specific requirements of sections 6 and 8. Activitiesdiscussed in this Standard may involve the use of haz-ardous materials, operations, and equipment. This Stan-dard does
28、not purport to address all of the safetyrequirements associated with their use. The owners testprogram shall establish appropriate safety and healthpractices and determine the applicability of regulatoryrequirements.3.1 Test InstrumentsA calibration program shall be established in accor-dance with A
29、SME NQA-1 requirements. All permanentand temporary test instruments used in the conduct oftests required by this Standard shall be in calibration.Instrument accuracy shall meet or exceed the require-ments of Table 1.3.1.1 Range Requirements. The full-scale range ofinstruments shall be limited as nec
30、essary to ensure thatthe readings are within the accuracy requirements ofTable 1.3.1.2 Instrument Fluctuation. Symmetrical damp-ing devices or averaging techniques may be used toreduce random signal fluctuations. Hydraulic instru-ments may be damped by using gage snubbers or throt-tling valves in in
31、strument lines.3.1.3 Evaluation Following Test Instrument Loss,Damage, or Calibration Failure. When a test instrumentis lost, damaged, or otherwise fails to meet the require-ments of Table 1 during calibration, all test resultsobtained using the instrument shall be evaluated, datingback to the time
32、of the previous calibration. If the evalua-tion does not confirm that the instrument met the accept-ance criteria for the test(s) in question, the test(s) shallbe repeated with calibrated instruments.ASME N511-2007Table 1 Instrument Accuracy RequirementsMeasurement Range Accuracy Note (1)Pressure 1

39、e Values. Referencevalues are determined during acceptance testing (ASMEAG-1, Article TA-4000), when the equipment or system3is proven to be operating within the acceptable limits ofthe design specification. Operating tests and inspectionsspecified in ASME AG-1, Article TA-4000 are performedunder co

All test results and associated analyses areincluded in the test procedure documentation.3.2.2 Reestablishment of Reference Values FollowingComponent Replacement, Repair, or Modification.
41、 Fol-lowing component replacement, repair, or modificationrequiring disassembly, an evaluation shall be conductedto determine the effect on current reference values.Whenever the evaluation indicates any of the referencevalues have been affected, new reference values shall beestablished in accordance
42、 with para. 3.2.1 or the previousreference values reverified. Evaluation of the new refer-ence values shall verify that the component conformsto the acceptance criteria prior to accepting it as fullyoperational. The evaluation to determine the effect onreference values shall be documented.3.3 Inspec

The owner shall document whichrequirements are applicable (see Mandatory AppendicesI through IV for development guidance).3.3.4 In-Service Tests. In-service tests shall be con-ducted at interva
48、ls not to exceed those specified in sec-tion 5 or the owners test program, whichever is mostlimiting. In-service test intervals are maximum intervalsallowed by this Standard and should not be used asdefault intervals in the absence of system-specific evalu-ations. Specific system test intervals shou
