Designation:F237904(Reapproved 2010)An American National StandardStandard Test Method forEnergy Performance of Powered Open Warewashing Sinks1This standard is issued under the fixed designation F2379;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method evaluates the energy consumption ofpowered open warewashing sinks.The food service operatorcan use these tests to evaluate and select a suitable washingdevice and understand its energy consumption.1.2 This test method applies to powered open warewashingsinks(powered sinks)with the following characteristics:alarge main water sink with electrically powered water pump(s)and multiple high flow water nozzles.The unit may include gasor electric heaters to maintain water temperature.These pow-ered sinks are designed to run for predetermined cycle durationand accommodate pots and pans of various shapes and sizes aswell as cooking utensils.They are intended for stand alone useand require little supervision.The powered sink will be testedfor the following(where applicable):1.2.1 Maximum energy input rate(10.2),1.2.2 Preheat energy consumption and duration(10.3),1.2.3 Idle energy rate(10.4),1.2.4 Pilot energy rate,if applicable(10.5),and1.2.5 Washing cycle energy consumption(10.6).NOTE1This test method applies only to the powered portion of theunit.Other compartments(sanitizing,rinsing,and so forth)are notevaluated.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D3588 Practice for Calculating Heat Value,CompressibilityFactor,and Relative Density of Gaseous Fuels2.2 ANSI Standard:2000 International Fuel Gas Code32.3 ASHRAE Documents:ASHRAE Guideline 2(RA90)Engineering Analysis of Ex-perimental Data4ASHRAE 1993 Fundamentals Handbook43.Terminology3.1 Definitions:3.1.1 powered open warewashing sink,or powered sink,nan all-purpose,stainless steel water sink with electricallypowered water pump(s)and multiple high flow water nozzlesdesigned for cleaning pots,pans,and utensils.The mainwashing sink holds 60 to 100 gal of heated water.The unit mayor may not feature a scrapper sink,rinse tank,sanitizing tank,scrap table,or a drain table,or both.3.1.2 test method,na definitive procedure for theidentification,measurement,and evaluation of one or morequalities,characteristics,or properties of a material,product,system,or service that produces test results.3.1.3 uncertainty,nmeasure of systematic and precisionerrors in specified instrumentation or measure of repeatabilityof a reported test result.3.2 Definitions of Terms Specific to This Standard:3.2.1 energy input rate,npeak rate at which a poweredsink consumes energy(Btu/h or kW(kJ/h).1This test method is under the jurisdiction of ASTM Committee F26 on FoodService Equipment and is the direct responsibility of Subcommittee F26.06 onProductivity and Energy Protocol.Current edition approved March 1,2010.Published May 2010.Originallyapproved in 2004.Last previous edition approved in 2004 as F2379 04.DOI:10.1520/F2379-04R10.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.4Available from American Society of Heating,Refrigerating,and Air-Conditioning Engineers,Inc.(ASHRAE),1791 Tullie Circle,NE,Atlanta,GA30329,http:/www.ashrae.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.2 idle energy rate,nthe rate of energy consumed(Btu/h or kW(kJ/h)by the powered sink while holding ormaintaining a water-filled wash sink at the 115F(46C)setpoint.3.2.3 pilot energy rate,naverage rate of energy consump-tion(Btu/h)by a powered sinks continuous pilot(if appli-cable).3.2.4 preheat energy,namount of energy consumed by thepowered sink while preheating the wash sink water from 70 65F(21 6 3C)to 115F(46C),with the control(s)set to acalibrated 115F(46C).3.2.5 preheat rate,naverage rate(F/min)at which thepowered sinks water is heated from 70 6 5F(21 6 3C)to115F(46C),with the control(s)set to a calibrated 115F(46C).3.2.6 preheat time,ntime required f
