1、Designation: C616/C616M 10Standard Specification forQuartz-Based Dimension Stone1This standard is issued under the fixed designation C616/C616M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in
2、 parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers the material characteristics,physical
3、 requirements, and sampling appropriate to the selec-tion of quartz-based dimension stone for general building andstructural purposes. Refer to Guides C1242 and C1528 for theappropriate selection and use of quartz-based dimension stone.1.2 Quartz-based dimension stone shall include stone that issawe
4、d, cut, split, or otherwise finished or shaped, and shallspecifically exclude molded, cast, or otherwise artificiallyaggregated units composed of fragments, and also crushed andbroken stone.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The val
5、ues stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.2. Referenced Documents2.1 ASTM Standards:2C97/C97M Test Methods for Absorption and Bulk Specific

23、orton Treatment 138S) has been changed. The new abrasive iscurrently more aggressive, resulting in lower Havalues than when the standard was initially established. As such, care should be taken when interpreting Hatest results,both with regard to this standard and with regard to historical data from
24、 the same quarry source. Committee C18 is actively studying alternatives to deal with this issue.CAbrasion Resistance Test Method C1353 will eventually replace Test Method C241/C241M and it is not necessary to perform both tests. Availability of the properequipment and materials by the testing laboratory may determine which test is performed.DNot recommended for paving in areas subject to heavy foot traffic.C616/C616M 102
