5.2.3 Pressure Boundary Leak Test. When a fanhousing is part of the system pressure boundary, a pres-sure boundary leak test shall be conducted to verify theleak tightness of the fan housing, shaft seal, and attachedinterfaces in accordance with para.4.2 and MandatoryAppendix II. The fan housing, shaft seal, and attachedinterfaces may be tested concurrent with the duct andhousing leak test specified in para.5.4.3.1.
5.2.4 System Functional Tests. Paragraphs 5.2.4.1through 5.2.4.5 shall be conducted in the same timeframe.
5.2.4.1 Mechanical Run Test. The fan shall be oper-ated at the design flow rate for at least 15 min and stablesystem operation (no surging) verified.
5.2.4.2 Flow Rate Test.The fan flow rate shall bemeasured. Recommended procedures are contained inIndustrial Ventilation (ACGIH) or equivalent.
5.2.4.3 Static Pressure Test.The fan inlet and out-let static pressure and velocity pressure shall be mea-sured and the overall fan static pressure determined.
5.2.4.4 Rotational Speed Test.Direct drive config-urations may be tested at the fan or motor. When a fandoes not have a direct drive coupling to the motor, therotational speed of the fan shaft shall be measured.
5.2.4.5 Vibration Test.The vibration of each fanand motor bearing shall be measured in accordance withpara.4.3.
5.3 Damper In-Service Tests
This section provides the in-service test requirementsfor dampers and related accessories. Integrated systemtesting shall be conducted in accordance with para.5.10.
5.3.1 In-Service Test Requirements. In-service testslisted in Table 4 shall be conducted at the specified inter-val and test results verified to be within the acceptancelimits of the owner’s test program and section 6 andbe compared with the reference values obtained in theacceptance tests in ASME AG-1, section TA-4200.
5.3.2 visual Inspection.A visual inspection of thedampers and associated components shall be conductedin accordance with para. 4.1 and Mandatory Appendix I(section I-3).
5.3.3 Pressure Boundary Leak Test,Damper Seat.When dampers have seat leak rate limits, a dynamicpressure boundary leak test shall be condducted in thedirection the damper is expected to function, in accor-dance with para.4.2 and Mandatory Appendix l.Seatleakage shall be tested by blanking off or othervviseisolating a duct section upstream of the damper.Thelleak test shall be performed with the damper cycledclosed using its normal closing mechanism(exclusiveof any additional assistance).
5.3.4 Component Functional Tests. Componentfunctional tests shall verify that the damper is opera-tional prior to conducting the system functional testsspecified in para.5.3.5.
5.3.4.1 Position Indication Test. Dampers havingremote position indicators shall be observed duringoperation to verify that the damper position correspondsto the remote indicator.
5.3.4.2 Exercise Test.Power-operated dampersshall be fully cycled using a control switch or otheractuating device to verify operation. Manual dampers,which have a shut off function, shall be fully cycled toverify operation.Fire dampers shall be tested in accor-dance with para.5.3.5.2.
5.3.4.3 Static Timing Test. Power-operated damp-ers that are required to operate within a specified timelimit shall be tested by measuring the time to fully openor close (as required by the owner’s test program).
5.3.5 System functional Tests
5.3.5.1 Flow Control Test.Power-operated damp-ers that control airfloww shall be observed under throttledflow conditions to verify freedom of movement andstable operation.
5.3.5.2 Fire Damper Test. Fire dampers shall betested, using a normal or simulated actuation signal, toverify activation under design flow.
5.3.5.3 Dynamic Timing Test.Isolation dampershaving a required actuation response time shall be testedto the fully open or closed position (as required by theowner’s test program) under design flow rate condi-tions.
5.3.5.4 Interlock Test. Dampers that have an open-ing or closing function interlocked with other compo-nents (e-g., fan, other dampers,etc.) shall be tested toverify interlock action.
5.4 Duct and Housing In-Service Tests
This section provides the in-service test requirementsfor ducts and housings.
5.4.1 In-Service Test Requirements. In-service tests listed in Table 5 shall be conducted at the specified inter- val 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-1, 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 I-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.
