34、pecified in the contract or purchaseorder, sampling for inspection should be performed in accor-dance with ANSI Z1.4.10.2 Measure and inspect the dispensers prepared for ship-ment for performance, safety, and appearance by a qualifiedquality audit program.11. Test Methods11.1 GeneralPrior to the per
35、formance of the tests speci-fied herein, the unit shall be operated for a period of timerecommended by the manufacturer for adjustment of the unit.The room temperature may vary from 70 to 80F (21 to 27C);and tap water having a minimum of 30 psi and a maximum of125 psi (206 and 861 kPa) flowing press
36、ure may be used as nowater heating is required.11.2 Energy Consumption:11.2.1 Significance and UseThe purpose of this test is todetermine the energy consumption for the dispenser modelbeing tested.11.2.2 ProcedureThe energy consumed by the dispenserincludes the augering device and solenoid valve, wh
37、ich runonly when a drink is dispensed, as well as a heater, if provided,to protect the powder from humidity. The energy used is relatedto the number of drinks drawn, as well as the humidityprotective heater. To estimate the daily energy consumed,proceed as follows:11.2.2.1 Measure kilowatts with the
38、 dispenser plugged inand the power switch, if provided, to “on” position, but withoutdispensing a drink. This will measure the humidity protectiveheater power if any is used.11.2.2.2 Connect a kilowatt hour meter to the dispenser anddispense one-hundred 8-oz. (235-mL) portions in 1 h. Theenergy meas
39、ured will include the anti-humidity heater as wellas the energy used for the augering device and the solenoid. Tocalculate the energy used for dispensing 100 drinks, subtractthe kilowatt hours consumed by the anti-humidity device fromthe total energy consumed.11.2.2.3 The energy for 24 h can be calc
40、ulated as follows:Energy, kW h/24 h 5 anti2humidity heater kW 3 241estimated drinks 8oz!/24 h!1003 kW h/100 drinks11.3 Water Flow:11.3.1 Significance and UseThe purpose of this test is toensure that the proper amount of water is dispensed.11.3.2 ProcedureWith the dispenser connected to a waterline w
41、ith a psig between 30 and 120 flow pressure, and thehopper removed or made inoperative, adjust the water flow forthe nominal water flow required for the product throw deter-mined in test specified in 11.5. After the adjustment, make 30consecutive electric timer-controlled water portions. Eachportion
42、 will be within 63 % of the volume.11.4 Ingredient Throw:11.4.1 Significance and UseThe purpose of this test is toensure that the proper amount of powder ingredient is depos-ited for an 8-oz (235-mL) serving.11.4.2 ProcedureWith the water flow made inoperative,add the proper powder ingredient and ad
43、just the powderingredient time for an 8-oz (235-mL) serving. After thisadjustment, make 30 consecutive portions (powder ingredientonly) and each shall be within 610 % of the desired setting.11.5 Humidity Test:11.5.1 Significance and UseThe purpose of this test is toensure that the dispenser will fun
44、ction properly in an environ-ment of high humidity.11.5.2 ProcedurePlace the dispenser in an environmentalchamber of 90 6 2F (32.2 6 1C) with 80 6 5 % humidity.Connect the water and install a full hopper. Record weight ofpowder at full hopper. During an 8-h period, draw at thestandard setting enough
45、 portions, evenly spaced over the 8-hperiod, for the product to empty the hopper or container. If,during the test, it is noted that no powder, or virtually nopowder, is dispensed during a dispensing cycle, terminate thetest and note the number of visually acceptable portions.Remove and weigh the bal
46、ance of the powder in the hopper;the balance shall not exceed 5 % of the original powder weight.12. Inspection12.1 End Item TestingTest one production item selected atrandom from each lot in accordance with applicable tests ofSection 11. Record performance results in a permanent filewith the informa
47、tion accessible to customers upon demand.Any subsequent change in design that would relate to perfor-mance shall require a new test record and evaluation ofminimum requirements.12.2 Quality Conformance InspectionThe manufacturingorganization shall have an effective quality audit system.12.3 Componen
48、t and Material InspectionInspect incom-ing components and material to the design parameters asspecified in drawings or purchase documents, or both.13. Certification13.1 When specified in the purchase order or contract, thepurchaser shall be furnished certification that samples repre-senting each lot
49、 have been tested or inspected as directed in thisspecification and the requirements have been met. Whenspecified in the purchase order or contract, a report shall befurnished on this testing and inspection.14. Product Marking14.1 Each dispenser shall be provided with an identificationplate or adjacent plate(s) securely affixed to the item. Theplate(s) and its markings shall meet UL 73 requirements forlabels on indoor equipment.15. Manuals15.1 Format and content of applicable manuals shall be asindicated in Specification F 760.F 1023
