Designation:E116013Standard Guide forOn-Site Inspection and Verification of Operation of SolarDomestic Hot Water Systems1This standard is issued under the fixed designation E1160;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 guide covers procedures and test methods forconducting an on-site inspection and acceptance test of aninstalled domestic hot water system(DHW)using flat plate,concentrating-type collectors or tank absorber systems.1.2 It is intended as a simple and economical acceptance testto be performed by the system installer or an independent testerto verify that critical components of the system are functioningand to acquire baseline data reflecting overall short termsystem heat output.1.3 This guide is not intended to generate accurate measure-ments of system performance(see ASHRAE standard 95-1981for a laboratory test)or thermal efficiency.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.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Documents2.1 ASTM Standards:2E823 Practice for Nonoperational Exposure and Inspectionof a Solar Collector(Withdrawn 2010)3E1056 Practice for Installation and Service of Solar Domes-tic Water Heating Systems for One-and Two-FamilyDwellings2.2 ASHRAE Standards:93-1986(ANSI B198.1-1977)Method of Testing to Deter-mine the Thermal Performance of Solar Collectors495-1981 Method of Testing to Determine the Thermal Per-formance of Domestic Water Heating System42.3 NIST Standard:76-1137 Thermal Data Requirements and PerformanceEvaluation Procedures for the National Solar Heating andCooling Demonstration Program52.4 ISO Standard:69806 Test Methods for Solar Collectors3.Summary of Guide3.1 This guide recommends inspection procedures and testsfor:general system inspection,collector efficiency,freezeprotection,and controller and pump/blower operation.3.1.1 Verification of satisfactory operation of these compo-nents indicates that the system is functioning.Tests aredesigned to take a minimum of time in preparation,testing andrestoration of the system.They may use relatively inexpensive,nonintrusive instrumentation which system installers can rea-sonably be expected to have on hand.3.2 Recommended tests for each component or subsystemfall into categories according to the level of complexity andcost(Note 1).3.2.1 Category AThe most rudimentary tests,such asvisual inspection.3.2.2 Category BTests that require minimal instrumenta-tion and skill.3.2.3 Category CTests that require most expensive orsophisticated instrumentation or more time to perform.NOTE1Category B tests should include Category A tests asprerequisite,etc.3.2.4 Selection of the appropriate test is at the discretion ofthe tester and purchaser,who should be aware of the tradeoffsbetween cost and accuracy at each level of testing.The tester1This guide is under the jurisdiction of ASTM Committee E44 on Solar,Geothermal and OtherAlternative Energy Sources and is the direct responsibility ofSubcommittee E44.05 on Solar Heating and Cooling Systems and Materials.Current edition approved Nov.1,2013.Published December 2013.Originallyapproved in 1987.Last previous edition approved in 2007 as E1160-87(2007).DOI:10.1520/E1160-13.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from ASHRAE,1791 Tullie Circle,N.E.,Altanta,GA 30329.5Available from National Institute of Standards and Technology,Gaithersburg,MD 20899.6Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 should make these clearly known to the purchaser of thesystem who may wish to assume the costs of more sophisti-cated testing(Note 2).Preferably there should be a part of theinstallation contract between the tester and purchaser spellingout test specifics(for example,Category A,B or C for eachsubtest).NOTE2Consult your local National Balancing Bureau or AssociatedAir Balance Council.3.3 Instrumentation includes sensors to monitor some or allof the following conditions:3.3.1 Total incident solar radiation(in the plane of thecollector array),3.3.2 Ou
