5、authorities and with the cooperation of themanufacturers of these products, the ASSE Standards Committee authorized this project for thedevelopment of an ASSE Standard.Its objective was to construct a sound and reasonable set of performance guide lines for theplumbing requirements of these hot water
6、 dispensers when installed in a system of plumbing.The work of constructing these requirements was assigned to a subcommittee under thedirection of the Standards Committee.ii Hot Water Dispensers Household Storage Type ElectricalASSE #1023 1979ASSE Standards CommitteeRobert J.

10、and for compliance with 1.7.2.2 Hot Water Dispensers Household Storage Type ElectricalASSE #1023 19791.7.2 The dispenser shall be so constructed as to prevent the creation of hazardous conditionsin the event that the heater is energized when the tank is dry.1.8 Useful Hot WaterTo obtain uniformity o
11、f comparative ratings of useful hot water, all dispensers should be rated bythe following formula disregarding ambient heat loss:Rh= 0.00368 x WWhere: Rh= Recovery, gallons per hourW = Watts shown on the name plate, or amps shown on name plate times name plate voltage.This formula is based on a wate

The dispenser shall betaken from the m

See also 1.1.1.2Method of TestThis test is combined with that of 2.3.2.3 Leakage and DrippageThere shall be no
14、 leakage from the unit during a dispensing cycle nor a continuous drippage fromthe dispensing nozzle following a dispensing cycle or during any standby period. This latterrequirement is waived during the heating of the tank from a cold start.Method of TestThe test unit shall be set up according to t
15、he manufacturers instructions and be connected to anadequate water and electric supply. A thermocouple shall be installed just inside the dispensingnozzle within the water stream. The electric supply must be capable of maintaining the voltage andamperage, or wattage, shown on the name plate. Previou
16、s to energizing the heater, open thesupply valve and hold the dispensing valve open until water runs freely from the dispensing nozzle.Energize the heater. When the thermostat opens at the tank service water temperature, open thedispensing valve and check the maximum temperature of the discharging w
17、ater. Allow the waterto flow until the thermostat closes and immediately close the dispensing valve. Allow the tank toheat until the thermostat again opens. Observe for any drippage from the nozzle. Repeat the abovetest. Following this, run 10 dispensing cycles drawing 6 oz. of water for each cycle
18、allowing a periodof two minutes between the draws. Observe for any drippage from the nozzle.2.4 Product RejectionFailure to comply with any requirement of this standard shall be cause for the rejection of the modelof the device tested.4 Hot Water Dispensers Household Storage Type ElectricalASSE #1023 1979American Society of Sanitary EngineeringFOR PLUMBING AND SANITARY RESEARCH901 Canterbury Road, Suite A Westlake, Ohio 44145-1480 USATEL: (440) 835-3040 FAX: (440) 835-3488E-mail: general.infoasse-plumbing.org Web: http:/www.asse-plumbing.org
