Designation:E110715Standard Test Method forMeasuring the Throughput of Resource-Recovery UnitOperations1This standard is issued under the fixed designation E1107;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 is for measuring the throughput,ormass flowrate,of a resource-recovery unit operation,or seriesof unit operations.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.2.1 ExceptionSection 9.1.2 indicates the equivalentweight in pounds for samples with particle size greater than 90mm.1.3 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.Specific precau-tionary information is given in Section 7.2.Referenced Documents2.1 ASTM Standards:2D75 Practice for Sampling AggregatesE868 Test Methods for Conducting Performance Tests onMechanical Conveying Equipment Used in ResourceRecovery Systems(Withdrawn 2013)33.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 binary separatora mechanical device that separatessingle input feed stream into two output feed streams.3.1.2 polynary separatora mechanical device that sepa-rates single input feed stream into three or more output feedstreams.3.1.3 processora type of resource recovery unit operationwith a single input feed stream and single output stream.Itsfunction is to alter the physical or physico-chemical propertiesof the input feed stream.The mass flow rates of input andoutput streams should be equal unless moisture is lost.3.1.4 throughputthe mass flowrate through a unitoperation,expressed,preferably,in units of kilograms per hour(kg/h)or alternatively in units of pounds per hour(lb/h).3.1.5 unit operationa basic step in a larger process con-sisting of multiple steps.4.Summary of Test Method4.1 The output streams of a separator or processor arecollected over a measured period of time and weighed.Collection of the output stream is either in containers or bystopping,then clearing,portions of conveyor belts or chutes.For processing equipment in which materials separation is notaccomplished,the input stream may be sampled if this is moreconvenient.5.Significance and Use5.1 This test method is used to document the mass flowrateof a resource recovery unit operation in a plant and as a meansof relating operation to design objectives.5.2 This test method is also used in conjunction withmeasurements of the performance of materials separators(particularly recovery and purity).As such,throughput shouldnot generally be measured by sampling the feed since this maychange its performance.Processing equipment that does notperform separations can be sampled at either the feed orproduct streams.6.Apparatus6.1 Collection BinsSeveral size collection bins are re-quired.The size is determined by the size of sample,which inturn,is determined by the throughput of the plant.Somestreams can be sampled into drums or barrels.6.1.1 All containers must be clean and in good mechanicalcondition,and not have rusting,flaking,or mechanicallyweakened sections.Containers should be cleaned with water oran air hose prior to use.(WarningAir hoses must be usedwith appropriate safety equipment to avoid personal injury.)1This test method is under the jurisdiction of ASTM Committee D34 on WasteManagement and is the direct responsibility of Subcommittee D34.03 on Treatment,Recovery and Reuse.Current edition approved Sept.1,2015.Published September 2015.Originallyapproved in 1986.Last previous edition approved in 2010 as E1107 10.DOI:10.1520/E1107-15.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.1.2 The tare weight of the containers should be clearlymarked with paint and checked periodically.Provision may bemade for bin covers for the sampling and containment ofmaterials that can be blown or spilled.Covers must be markedto indicate whether or not they are included in the tare weightof the container.6.2 ScalesThe type and size of scales varies with the sizeof the samples obtained.Containers as small as perhaps a drumto as large as perhaps a tote bin,roll-off container,or even fulltruck may be used.All scales should have a precision andaccuracy of 60.1%of
