5.4.1 In-Service Test Requirements. In-service tests listed in Table 5 shall be conducted at the specified interval and test results verified to be within the acceptance limits of the owner’s test program and section 6. Test results shall be compared with the reference values obtained in the acceptance tests in ASME AG-I, section TA-4300.
5.4.2 Visual Inspection. A visual inspection of the ducts, housings, and associated attachments shall be conducted in accordance with para. 4.1 and Mandatory Appendix I (section 1-4).
5.4.3 Pressure Boundary Leak Test. A pressure boundary leak test shall be conducted on filter housings and applicable ductwork in accordance with para. 4.2 and Mandatory Appendix II.
5.5 Refrigeration Equipment In-Service Tests
This section provides the in-service test requirements for refrigeration equipment. Integrated system testing shall be conducted in accordance with para. 5.10.
5.5.1 In-Service Test Requirements. In-service tests listed in Table 6 shall be conducted at the specified interval and test results verified to be within the acceptance limits of the owner’s test program and section 6. Test results shall be compared with the reference values obtained in the acceptance tests in ASME AG-i, section
TA-4400.
5.5.2 Visual Inspection. A visual inspection of the refrigeration equipment components shall be conducted in accordance with para. 4.1 and Mandatory Appendix I (section 1-5).
5.5.3 Pressure Boundary Tests
5.5.3.1 Refrigerant Piping and Coils. The refrigerant system shall be monitored under normal operating conditions to verify no unacceptable refrigerant leaks in excess of the limits specified in the applicable sections of ASME AG-I and the owner’s test program.
5.5.3.2 Hydronic Piping and Coils. Hydronic piping and coils shall be observed to verify no unacceptable fluid leaks. Testing shall be conducted by inspecting the fluid system, under normal operating pressure, for evidence of leaks in excess of the limits specified in the applicable sections of ASME AG-I and the owner’s test program.
5.5.4 Component Functional Tests
5.5.4.1 Fans. Fans shall be tested in accordance with para. 5.2.
5.5.4.2 Valve Position Indication Test. Valves with
position indicators shall be observed during valve full- stroke operation to verify that the valve position corresponds to the remote indication.
5.5.4.3 Valve Exercise Test. Power-operated valves shall be fully stroked using their remote control switch or other actuation device to verify operation. Manual valves shall be fully stroked to verify freedom of movement.
5.5.4.4 Valve Timing Test. Power-operated valves that are required to operate within a specified time limit shall be tested by measuring the stroke time.
5.5.5 System Functional Tests
5.5.5.1 Flow Control Valve Test. Power-operated
valves, controlled by flow instrumentation, shall be observed under throttled flow conditions to verify freedom of movement and stable operation.
5.5.5.2 MechanicaL Run Test. The refrigeration compressor shall be operated with the system operating in the normal heat load range for at least 15 mm and stable system operation verified.
5.5.5.3 Performance Test. The refrigeration compressor inlet and outlet pressure and temperature shall be measured with the refrigeration equipment operating within its design load range.
5.5.5.4 Vibration Test. The vibration on accessible motor, fan, compressor, and pump-bearing housings in the refrigeration system shall be measured in accordance with para. 4.3.
