1、Designation:C160610(Reapproved 2014)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 o
2、f 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 ToxicityCharacteris
3、tic 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
4、.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 to determine theapplicability of regulatory limitations prior to use.2.Referenced Docum

6、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 glas
7、s 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
8、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
9、 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
10、 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.8.Sampling,Test Specimens,and T
11、est 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.1This test method is under the jurisdiction ofASTM Committee C21 on CeramicWhitewares and Related Productsand i

14、 States1 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,a
15、long 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 glass to create pieces that can be fed intothe roll or disc mill.9.3 Clean both the mill and riffle box,prior to use.9.4 Feed the pre-broken glass into t
16、he disc mill or roll millas feedstock.9.4.1 Grind the glass as two separate lots,with the selectedmill apertures set between 2.5 mm and 3.5 mm.Theseaperature settings tend to produce crushed glass with a maxi-mum particle size of 5 mm.9.5 Any oversized material must be removed by sieving orhand picking,and be broken up prior to blending back into theoriginal sample.9.6 Homogenize the sample using a roller or tumblerapparatus.9.7 Immediately pass sample through the riffle box collect-ing two sub-
