Common use of Conducting the Test Clause in Contracts

Conducting the Test. Capacity and thermal performance testing will be conducted by Seller and witnessed by Buyer at its discretion. 5.1 A minimum of three test points will be conducted on each unit. Each test point will be conducted with the gas turbine power equipment and all test instrumentation functioning satisfactorily and in a steady-state condition with evaporative coolers in service and with the ▇▇▇▇ V control system indicating that the unit is at base load. Prior to and during each test point, the gas turbine wheel space temperatures will be monitored individually to verify thermal stability. The gas turbine will be considered in a steady state condition when each turbine wheel space temperature changes by no more than 5EF over a fifteen minute period. The unit thermal stability will be documented by print-outs from the unit control system. 5.2 In accordance with ASME PTC-22 (1997), additional parameters will be monitored during each test point to verify that the system is in a steady state condition. These parameters and corresponding limits of variation are listed in the following table: Table: Steady-State Conditions Summary Turbine Wheelspace Temperature (each) Prior to and during test point n/a May not change more than 5EF over any 15 minute period Ambient Temperature During test point ± 4/o/F Variation from test point average may not exceed limit Wet Bulb Temperature During test point ± 3/o/F Variation from test point average may not exceed limit Gross Power Output During test point ± 2.0% Variation from test point average may not exceed limit Barometric Pressure During test point ± 0.5% Variation from test point average may not exceed limit 5.3 In accordance with ASME PTC-22 (1997), each test point will be conducted over a thirty minute time period. Data will be recorded at five minute intervals (or more frequently) throughout the duration of the test point for a minimum of seven complete sets of instrument readings. No test point should exceed thirty minutes nor should the data recording interval exceed ten minutes.

Fuel samples will be delivered to a reputable third party laboratory for analysis. As a backup, duplicate fuel samples will be retained at the site until all fuel analysis is completed. 5.5 Testing shall be conducted with the inlet bleed heat system off and isolated.
