3 Terms and Definitions

The following terms and definitions apply to this document.

4 Purpose of the test

4.1 Verify that system performance is consistent with specified requirements. The thermal performance test should simulate the operating conditions of the power plant as much as possible, including expected operating events at the temperature, pressure, and flow rate.

4.2 Verify the efficiency of the insulation and cooling system as far as possible. The test will initially check flow, vibration, clearance and other adaptations to the component or system measures taken to expand. The test shall verify the operation of instruments and other equipment at high temperatures, and confirm the relevant operating techniques.

4.3 The duration of the thermal performance test shall be such that the test reaches steady state operating conditions to determine whether structures, systems and components can be operating conditions.

5 Test conditions

The test conditions of the thermal performance test before charging mainly include.

a) The organizational structure, division of responsibilities, human resources, planning and administrative management have been arranged; […]
