Designation:F169615An American National StandardStandard Test Method forEnergy Performance of Stationary-Rack,Door-TypeCommercial Dishwashing Machines1This standard is issued under the fixed designation F1696;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 covers the evaluation of the energy andwater consumption of single-rack,door-type commercial dish-washers(hereafter referred to as dishwashers).Dishwashersmay have a remote or self-contained booster heater.This testmethod does not address cleaning or sanitizing performance.1.2 This test method is applicable to both hot water sanitiz-ing and chemical sanitizing stationary rack machines,whichincludes undercounter single rack machines,upright door-typemachines,pot,pan and utensil machines,fresh water rinsemachines and fill-and-dump machines.Dishwasher tank heat-ers are evaluated separately from the booster heater.Machinesdesigned to be interchangeable in the field from high temp andlow temp(that is,Dual Sanitizing Machines)and vice versa,shall be tested at both settings.Machines should be set forfactory settings.If a dishwasher includes a booster heater as anoption,energy should be sub metered separately for the boosterheater.When the test method specifies to use the data plate ormanufacturers recommendations,instructions,specifications,or requirements,the information source shall be used in thefollowing order of preference and documented in the testreport:data plate,user manual,communication with manufac-turer.1.3 The following procedures are included in this testmethod:1.3.1 Procedures to Confirm Dishwasher is OperatingProperly Prior to Performance Testing:1.3.1.1 Maximum energy input rate of the tank heaters(see10.3).1.3.1.2 Maximum energy input rate of the booster heater,ifapplicable(see 10.4).1.3.1.3 Water consumption calibration(see 10.5).1.3.1.4 Booster temperature calibration,if applicable(see10.2).1.3.1.5 Tank temperature calibration(see 10.7.6.1 and10.7.6.2).1.3.2 Energy Usage and Cycle Rate Performance Tests:1.3.2.1 Washing energy test(see 10.7).1.3.2.2 Idle energy rate(door(s)open and door(s)closed)(see 10.8).1.4 The values stated in inch-pound units are to be regardedas standard.The SI units given in parentheses are for informa-tion only.1.5 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 FuelsF857 Specification for Hot Water and Chemical SanitizingCommercial Dishwashing Machines,Stationary RackTypeF861 Specification for Commercial Dishwashing RacksF953 Specification for Commercial Dishwashing Machines(Stationary Rack,Dump Type)Chemical Sanitizing2.2 NSF Standards:3NSF/ANSI 3 Commercial Warewashing EquipmentNSF/ANSI 170 Glossary of Foodservice Terms2.3 ASHRAE Document:4ASHRAE Guideline 2-1986(RA90)Engineering Analysisof Experimental Data3.Terminology3.1 Definitions: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 Aug.1,2015.Published October 2015.Originallyapproved in 1996.Last previous edition approved in 2014 as F1696 14.DOI:10.1520/F1696-15.2For 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 NSF International,P.O.Box 130140,789 N.Dixboro Rd.,AnnArbor,MI 48113-0140,http:/www.nsf.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 3.1.1 ambient temperature,ndefined in NSF/ANSI 170-2014;Section 3.3.3.1.2 auxiliary rinse,ndefined in NSF/ANSI 170-2014;Section 3.5.3.1.3 average tank temperature,ntemperature of the washtank measured within12in.of the factory installed thermostatbulb.The temperature is measured and averaged during the 10rack(6 racks for pot and pan or for undercounter)loaded roomtemperature washing test.The time interval for averagingincludes washing,rinsing,dwell,energy recovery(for heatrecovery dishwashers),wash tank temperature recovery andloading.For upright machines,the temperature averaged overthe entire period starting with the fi
