Designation:C160610(Reapproved 2018)Standard Test Method forSampling Protocol for TCLP Testing of ContainerGlassware1This standard is issued under the fixed designation C1606;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 defines the way in which containerglassware should be prepared before performing the ToxicityCharacteristic Leaching Procedure(TCLP).The method coversthe homogenization of the sample,and the selection of arepresentative portion of the sample to test and get reproduc-ible results.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2E691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods3.Summary of Test Method3.1 Container glass articles decorated with ceramic glassdecorations are broken to fit the requirements of the TCLPprotocol by using a disc mill or roll mill apparatus,and then thesamples are homogenized using a riffle box.A representativesample of the glass articles can then be put through the TCLPtest with reproducible results.4.Significance and Use4.1 Sampling of decorated glass containers for the TCLPcan vary greatly,resulting from the size and shape of the articlerelative to the amount of ceramic decoration on the ware.Breaking the glass can cause some of the pieces to have nodecoration on them,and others to be heavily decorated andmore likely to leach lead and cadmium under the TCLP test.This method provides an effective tool to homogenize the glasscontainers so that reproducible results can be attained from theTCLP test.5.Apparatus5.1 Pre-breaking apparatus,consisting of:5.1.1 Two L(or larger)polythene bucket with a tightlysealed lid,5.1.2 One or two clean 35 to 40 mm diameter aluminagrinding balls,5.2 Disc mill or roll mill,5.3 Sieves,as needed,5.4 Riffle box,and5.5 Roller or tumbler apparatus.6.Reagents and Materials6.1 Glassware to be tested,in two sets of 10 units each.7.Hazards7.1 When working with glassware,always be aware andcareful of the potential of getting cut by the glass.Personalprotective equipment,such as a face shield or goggles,leathergloves,and a protective apron should be worn when workingwith glass.Take precautions when working with the samples andapparatus to avoid the possibilities of getting hurt.1This test method is under the jurisdiction ofASTM Committee C21 on CeramicWhitewares and Related Productsand is the direct responsibility of SubcommitteeC21.03 on Methods for Whitewares and Environmental Concerns.Current edition approved Oct.1,2018.Published October 2018.Originallyapproved in 2004.Last previous edition approved in 2014 as C1606 10(2014).DOI:10.1520/C1606-10R18.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 8.Sampling,Test Specimens,and Test Units8.1 Since the amount of lead and cadmium that leaches froma decoration can be affected by the relative size of thedecoration,it is important to start with two sets of 10 unitseach.9.Procedure9.1 To minimize the variation of sampling,this testing shallbe done in duplicate,and therefore,take two sets of 10 units ofthe glassware to be tested.9.2 Pre-break the glass prior to milling,using the followingprocedure:9.2.1 Place the first set of glassware into the 2 L bucket,along with one or two clean 35 to 40 mm diameter aluminagrinding balls.9.2.2 After tightly sealing the lid,shake the vessel hardenough to smash the g
