The following information is based on that document and is included here for emphasisand for the convenience of the user of the Code. It is e

40、xpected that the Code user is fully cog-nizant of Sections 1 and 3 of ASME PTC 1 and has read them prior to applying this Code.ASME Performance Test Codes provide test procedures that yield results of the highest levelof accuracy consistent with the best engineering knowledge and practice currently

41、available. Theywere developed by balanced committees representing all concerned interests and specify proce-dures, instrumentation, equipment-operating requirements, calculation methods, and uncertaintyanalysis.When tests are run in accordance with a Code, the test results themselves, without adjust

42、mentfor uncertainty, yield the best available indication of the actual performance of the tested equip-ment. ASME Performance Test Codes do not specify means to compare those results to contrac-tual guarantees. Therefore, it is recommended that the parties to a commercial test agree beforestarting t

43、he test and preferably before signing the contract on the method to be used for com-paring the test results to the contractual guarantees. It is beyond the scope of any Code to de-termine or interpret how such comparisons shall be made.viFOREWORDA Joint AIEEASME (IEEEASME) Subcommittee on a Recommen

44、ded Specification Coveringthe Speed Governing of Hydraulic Turbine-Generators was organized in 1944. The specificationsprepared by this subcommittee were issued in September 1950 as AIEE (IEEE) Publication No.605 entitled “Recommended Specification for Speed-Governing of Hydraulic Turbines Intendedt

45、o Drive Electric Generators.”As a result of the publication of these specifications, the ASME Board on Power Test CodesCommittee recognized the need of a code for testing hydraulic turbine governors and organizedPower Test Code Committee No. 29 in 1955 to prepare this document.This committee prepare

46、d a code that was approved by the Power Test Codes Committee onMarch 7, 1963. Final publication was delayed, however, until a number of suggestions made bythe standing committee were considered and satisfactorily resolved. Reconciliation of these com-ments was effected through the efforts of Mr. W.

47、K. Cave, member of the committee, who un-dertook to complete the assignment on behalf of the group. The code was approved and adoptedby the Council of the Society by action of the Board of Codes and Standards on December 9, 1964.In February 1993, through the efforts of the Board on Performance Test

48、Codes member GeorgeH. Mittendorf, Jr., the Performance Test Code (PTC) Committee 29 was reestablished to updatethe code.The members of PTC Committee 29 wish to dedicate this document to the memory of William(Bill) Duncan. Bill served as the Committees Vice Chairman from 1993 until his untimely death

49、in an airplane crash on October 8, 1997. Bills accomplishments were many, but nothing was moresignificant than organizing and supporting the validation of the draft of this code with actual sitetesting of an hydraulic turbine governor.ASME PTC 29-2004 was adopted by the American National Standards Institute as an Ameri-can National Standard on February 23, 2005.viiPERFORMANCE TEST CODE COMMITTEE 29ON SPEED GOVERNING SYSTEMS FOR HYDRAULICTURBINE GENERATOR UNITS(The following is the roster of the Committee at the time of approval of this Code.)COMMITTEE OFFICERSR.
