ResaleNo reproduction or networking permitted without license from IHS --,,,,,,--,,,,,,,--- v NOTICE All Perance Test Codes must adhere to the requirements of ASME PTC 1, General Instruc- tions. The following ination is based on that document and is included here for emphasis and for the convenience of the user of the Code. It is expected 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 Perance Test Codes provide test procedures that yield results of the highest level of accuracy consistent with the best engineering knowledge and practice currently available. They were developed by balanced committees representing all concerned interests and specify proce- dures, instrumentation, equipment-operating requirements, calculation s, and uncertainty analysis. When tests are run in accordance with a Code, the test results themselves, without adjustment for uncertainty, yield the best available indication of the actual perance of the tested equip- ment. ASME Perance 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 before starting the test and preferably before signing the contract on the 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.

The specifications prepared by this subcommittee were issued in September 1950 as AIEE IEEE Publication No. 605 entitled “Recommended Specification for Speed-Governing of Hydraulic Turbines Intended to Drive Electric Generators.” As a result of the publication of these specifications, the ASME Board on Power Test Codes Committee recognized the need of a code for testing hydraulic turbine governors and organized Power Test Code Committee No. 29 in 1955 to prepare this document. This committee prepared a code that was approved by the Power Test Codes Committee on March 7, 1963. Final publication was delayed, however, until a number of suggestions made by the standing committee were considered and satisfactorily resolved. Reconciliation of these com- ments was effected through the efforts of Mr. W. K. Cave, member of the com
