17、ralInstructionswasfirstprintedinpreliminaryforminMechanicalEngineeringin 1920 and was presented at a public hearingat the spring meeting of the Society held in Chicago,Illinois in 1921. It was approved and adopted as a standards practice of the Society in 1924.During the years 1920 through 1970, the

18、 function of the Power Test Codes (as they were thenknown) continued to evolve and broaden. In recognition of these developments, the Code onGeneral Instructions was revised twice. The revisions were approved by the Council on June 17,1945 and May 7, 1970, respectively.During the years 1970 through

19、1985, the scope of the Power Test Codes, now known asPerformance Test Codes (PTCs), was further broadened as a result of(a) their designation as American National Standards by the American National StandardsInstitute (ANSI)(b) an increased awareness of the relationship between U.S. domestic standard

20、s and theirinternational counterpart and a related need to reconcile substantially conflicting requirementsbetween U.S. and international documents(c) clarification on the use of uncertainty in test codesThesedevelopmentsresultedinseveraladditionalrevisionstotheCodeonGeneralInstructionsthat were app

21、roved by the Board on Performance Test Code (BPTC) on May 13, 1970 (with theOctober 1971 Addenda), October 29, 1979, June 18, 1986, and June 12, 1991.The subsequent revision of the Code was initiated in mid-1998. A Project Team was appointedby the BPTC to develop this revision under the ASME Redesig

22、n Process. The revised documentwas approved by the BPTC on November 19, 1998.The next revision was a major updating of PTC 1. The existing information contained in PTC 1was divided into two separate documents. One is the code writers guide, the PTC 1 Template.The other, PTC 1, contains mandatory inf

23、ormation for all code users. This revision was approvedby the BPTC on December 9, 2003. It was also approved as an American National Standard bythe ANSI Board on Standards Review on March 10, 2004.The 2011 revision contained modifications to the 2004 version where by some new committeeswere added an

24、d others discontinued. The template was not updated at this time. The 2011revision was approved by the PTC Standards Committee on May 24, 2011 and approved andadopted as a Standard practice of the Society by action of the Board on Standardization andTesting on August 8, 2011. It was also approved as

25、 an American National Standard, by the ANSIBoard of Standards Review, on November 14, 2011.The current revision of PTC 1 modifies para. 1-6.3.1 to add another permissible use of testuncertainty to prepare for and validate the acceptability of a test. This method strictly specifieseach measurements s

26、ystematic uncertainty along with its permissible variation (data fluctuation)or a total measurement uncertainty, including both systematic and random effects for eachmeasured parameter and/or variable or each type of measured parameter or variable. A pretestand post-test uncertainty analysis is alwa

27、ys required. It is limited to demonstrating the achieve-ment of uncertainty limits placed upon each individual measurement without having to calculatea total test uncertainty for the result. However, if the user of the Code wishes to exceed any ofthe specified uncertainty limits of any parameter or

28、variable, a complete test uncertainty analysisis required to establish that the Codes limit level of uncertainty for the test result has been met.This requires utilizing the systematic, random, and/or total measurements uncertainty limits ofeach parameter and variable in accordance with PTC 19.1. On

29、ce the Code Limit Uncertainty isdetermined for the result, exceeding the upper limit of any individual parameters or variablesspecifieduncertaintyisallowableonlyifitisdemonstratedthattheselectionofallinstrumentationused will result in an overall test uncertainty equal to or less than what it would h

30、ave been hadall parameters uncertainty requirements been met. This recognizes the industrial need for anacceptable method that allows flexibility in the determination of total test uncertainty whileensuring that the specified overall test uncertainty is achieved. Also, the template is noivlonger req

31、uired by PTC 1, but it is recommended and is available on the PTC Web site(go.asme.org/PTCcommittee) for use as a reference.This edition of the Code was approved as an American National Standard, by the ANSI Boardof Standards Review, on September 9, 2015.vASME PTC COMMITTEEPerformance Test Codes(The

37、RODUCTIONThis document provides direction to users and code-writing committees of Performance TestCodes (PTCs). Code users shall consider it as part of each test.The objectives of PTC 1, General Instructions are as follows:(a) to define the purpose and scope of ASME PTCs(b) to list major industry ap

38、plications where PTCs can be used(c) to provide direction on the use of equipment PTCs concerning the planning, preparation,implementation, and reporting of test resultsviiiASME PTC 1-2015GENERAL INSTRUCTIONSSection 1Purpose, Scope, and Organization1-1 DEFINITION AND PURPOSEASME Performance Test Cod

39、es (PTCs) provide uni-formrulesandproceduresfortheplanning,preparation,execution, and reporting of performance test results.Test results provide numerical characteristics to the per-formance of equipment, systems, and plants beingtested. Throughout ASME PTC 1, when the term“equipment” is used with r

40、eference to the object of aperformance test, it can refer to specific equipment,systems, or to entire plants.1-2 STANDARDS COMMITTEESASME PTCs are developed by technical committeesthat are governed, organized, and appointed by thePerformance Test Codes Supervisory Committee underthe auspices of the

41、Board on Standardization andTesting. Each code-writing committee is organized toinclude representatives of several interest groups. Thequalificationsofeachmemberofacode-writingcommit-tee are subject to examination and approval by theSupervisory Committee. Members of the code-writingcommittees are hi

42、ghly qualified, technically competentprofessionals, generally members of ASME, who haveexpertise in the field or in an area of expertise neededby the committee, such as special instrumentation. Theypresent their views on matters under consideration asmembers of a learned profession, not as represent

43、ativesof employers or special interest groups.1-3 SCOPE AND ORGANIZATION OF PTCsMost ASME PTCs are applicable to a specified typeofequipmentdefinedbytheCode.Theremaybeseveralsubcategories of equipment covered by a single code.Types of equipment to which PTCs apply can be classi-fied into five broad

44、categories.(a) power production(b) combustion and heat transfer(c) fluid handling(d) emission(e) instruments, apparatus, and other supplementaldocuments1The quantities that characterize performance aredefined in each code for the equipment within its scope.Absolute performance characteristics determ

45、ined byadherence to a PTC can be evaluated as compared todesign or predicted characteristics, to previous testresults, or they can be used to benchmark or ascertainperformance at a particular time.SomePTCsarewrittenasgeneraldocumentsforrefer-ence in support of the equipment PTCs. These can beconside

46、red as technical reference material for the equip-ment codes. Three types of reference codes exist.Thefirsttypecoversinstrumentationusedinthemea-surement of thermodynamic or process fluid parame-ters, such as pressure, temperature, flow, and shaftpower. Such individual codes referring to process ort

47、hermodynamic quantities are known as PerformanceTest Code Instruments and Apparatus Supplements.They are supplementary to the information on manda-tory instrumentation requirements contained in theequipmentcodes.Instrumentationinformationinequip-ment test codes supersedes the information given inthe

48、se supplements, but otherwise these supplementsshould be incorporated by reference in equipment testcodes where deemed appropriate by the committee.The second type covers guidance and reference infor-mation. It currently consists of PTC 1, GeneralInstructions, and PTC 2, Definitions and Values. PTC

49、2contains standards for terms, units, values of constants,and technical nomenclature.The third type addresses how to analyze the uncer-tainties associated with measurement of all primaryparameters to develop overall test uncertainty. It cur-rently consists of PTC 19.1, Test Uncertainty.Figures 1-3-1 and 1-3-2 show the organization ofASME Performance Test Code categories.1-4 PHILOSOPHYPTCs provideguidelines fortest proceduresthat yieldresults of the highest level of accuracy based on currentengineering knowledge, taking into account test costsand the value of information obtained f
