Inlet air temperature data shall be averaged for each test run. Revisions are made periodically to the Code to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Code. Use of an ultrasonic flowmeter will likely result in a greater uncertainty for thecondensate flow measurement as compared to an inlineflow element. The result will be a set of values ofACC capability including the change causedby each test parameters decreased pertur-bation. Attached Files for Direct Download. Temperature measurements shall be made with instru-ments having an accuracy of at least 0. Simply mail, phone, fax, or E-mail us and an Information Central representative will handle your request.

This may include a situation asmf full electrical load cannot be attained or a case where a steam host is unavailable to accept process steam.

Prior to starting the test, the plant must be operated for a sufficient period of time at test load to demonstrate and verify stability in accordance with para.

Requests for Cases should also indicate theapplicable edition s of the Code to which the pc Case applies. Data review should start at the beginning of the test, providing an opportunity for immediate discov- ery of possible errors in instruments, procedures, or mea- surement methods. Bannister, Member Emeritus, Consultant J. A post-test uncertainty analysis is similarly required. Internal aeme points, such as basket tips and ther- mowells, should be located to avoid interference with internal steam duct structure, bracing, turning vanes, etc.

The cycle arrangement and operating conditionsshall be established during the agreement on testmethods. Therefore, the values have been read off thecurves rather than calculated. As a minimum, all of the operable fans of adjacent ACC units should be in operation during the test.

With no wind, a lower pressure is observed in the fans adjacent to the wind walls, but uniform in the three center fans. This Code shall not be construed as preventing the use of advanced technologies or methods of measurement not described herein, provided that asne uncertainty requirements of subsection are achieved.

Prior to starting each per-formance test, the following conditions must 30.11 Test inlet air temperature p The requestshould identify the Code, the paragraph, figure or table number sand be written as a Questionand Reply in the same format as existing Cases.

PTC Test Uncertainty.

If an instrument is found to be out of calibration, then its influence on the test shall be evaluated. Readings shall be taken at six positions 30 degapart around the circumference of the pipe. The request for interpretation should be clear and unambiguous. The inquirer may also include any axme or drawings that are necessary to explain the question; however, they should not contain proprietary names or information. Jorgensen, Member Emeritus, ConsultantJ. The ACC performance curves shall show the control- ling guarantee case and shall indicate the performance required for that case.


Turbine Back Pressure should correspond to one or two guarantee cases. Approved revisions will be published periodically.

When conductors larger than No. The operating cycle shallbe isolated to the maximum extent practical. Four-wire RTDs shall be used. It is beyond the scope of any Code to determine orinterpret how such comparisons shall be made.

In particular, it should be appreciated that the results of such a study would provide an estimate of the relationship of test results according to this Code and the expected daily operation at the site with its local topography and the existing environmental conditions. Connecting 301 Flow 1 in.

Exhaust Flow should correspond with each case. Absolute pressure transducers are required. Alternatively guideplates shall be constructed as shown in Fig.

It may be a flange or a landing bar for a weld. The condensatetemperature correction curves should consist of the con-densate temperature as function of the ACC pressureand total steam flow rate expressed in percentage ofdesign steam flow rate.
