Sampling and Quality Assurance10.1 SamplingWhen specified in the contract or purchase order, sampling for inspection should be performed in accordancewith ANSI Z1.4.10.2 Measure and inspect
37、the dispensers prepared for shipment for performance, safety, and appearance by a qualified qualityaudit program.11. Test Methods11.1 GeneralPrior to the performance of the tests specified herein, the unit shall be operated for a period of timerecommended by the manufacturer for adjustment of the un
38、it. The room temperature may vary from 70 to 80F (21 to 27C); andtap water having a minimum of 30 psi and a maximum of 125 psi (206 and 861 kPa) flowing pressure may be used as no waterheating is required.11.2 Energy Consumption:11.2.1 Significance and UseThe purpose of this test is to determine the
39、 energy consumption for the dispenser model beingtested.11.2.2 ProcedureThe energy consumed by the dispenser includes the augering device and solenoid valve, which run onlywhen a drink is dispensed, as well as a heater, if provided, to protect the powder from humidity. The energy used is related to
40、thenumber of drinks drawn, as well as the humidity protective heater. To estimate the daily energy consumed, proceed as follows:11.2.2.1 Measure kilowatts with the dispenser plugged in and the power switch, if provided, to “on” position, but withoutdispensing a drink. This will measure the humidity
41、protective heater power if any is used.11.2.2.2 Connect a kilowatt hour meter to the dispenser and dispense one-hundred 8-oz. (235-mL) portions in 1 h. The energymeasured will include the anti-humidity heater as well as the energy used for the augering device and the solenoid. To calculatethe energy
42、 used for dispensing 100 drinks, subtract the kilowatt hours consumed by the anti-humidity device from the total energyconsumed.11.2.2.3 The energy for 24 h can be calculated as follows:Energy, kW h/24 h 5 anti2humidity heater kW 3 24F1023-12_1F1023-12_211.3 Water Flow:11.3.1 Significance and UseThe
43、 purpose of this test is to ensure that the proper amount of water is dispensed.11.3.2 ProcedureWith the dispenser connected to a water line with a psig between 30 and 120 flow pressure, and the hopperremoved or made inoperative, adjust the water flow for the nominal water flow required for the prod
44、uct throw determined in testspecified in 11.5. After the adjustment, make 30 consecutive electric timer-controlled water portions. Each portion will be within63 % of the volume.11.4 Ingredient Throw:F1023 12311.4.1 Significance and UseThe purpose of this test is to ensure that the proper amount of p
45、owder ingredient is deposited foran 8-oz (235-mL) serving.11.4.2 ProcedureWith the water flow made inoperative, add the proper powder ingredient and adjust the powder ingredienttime for an 8-oz (235-mL) serving. After this adjustment, make 30 consecutive portions (powder ingredient only) and each sh
46、allbe within 610 % of the desired setting.11.5 Humidity Test:11.5.1 Significance and UseThe purpose of this test is to ensure that the dispenser will function properly in an environmentof high humidity.11.5.2 ProcedurePlace the dispenser in an environmental chamber of 90 6 2F (32.2 6 1C) with 80 6 5
47、 % humidity.Connect the water and install a full hopper. Record weight of powder at full hopper. During an 8-h period, draw at the standardsetting enough portions, evenly spaced over the 8-h period, for the product to empty the hopper or container. If, during the test,it is noted that no powder, or
48、virtually no powder, is dispensed during a dispensing cycle, terminate the test and note the numberof visually acceptable portions. Remove and weigh the balance of the powder in the hopper; the balance shall not exceed 5 % ofthe original powder weight.12. Inspection12.1 End Item TestingTest one prod
49、uction item selected at random from each lot in accordance with applicable tests of Section11. Record performance results in a permanent file with the information accessible to customers upon demand. Any subsequentchange in design that would relate to performance shall require a new test record and evaluation of minimum requirements.12.2 Quality Conformance InspectionThe manufacturing organization shall have an effective quality audit system.12.3 Component and Material InspectionInspect incoming components and material to the design p
