1、Designation: C 1606 04Standard Test Method forSampling Protocol for TCLP Testing of ContainerGlassware1This standard is issued under the fixed designation C 1606; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last rev

2、ision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、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 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibi

4、lity 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.

5、d3. 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

6、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

7、 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 a

8、pparatus, 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, and,5.5 Roller or tumbler apparatus.6. Reagents and Materials6.1 Glassware to b

9、e 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

10、precautions when working with the samples andapparatus to avoid the possibilities of getting hurt.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

11、 sets of ten 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:1This test method is under the jurisdicti
