2、. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the material characteristics, physical requirements, and sampling appropriate to the selection ofquartz-b
3、ased dimension stone for general building and structural purposes. Refer to Guides C1242 and C1528 for the appropriateselection and use of quartz-based dimension stone.1.2 Quartz-based dimension stone shall include stone that is sawed, cut, split, or otherwise finished or shaped, and shallspecifical
4、ly exclude molded, cast, or otherwise artificially aggregated units composed of fragments, and also crushed and brokenstone.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore,
5、 each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2.

The
25、 new abrasive iscurrently more aggressive, resulting in lower Ha values than when the standard was initially established. As such, care should be taken when interpreting Ha test results,both with regard to this standard and with regard to historical data from the same quarry source. Committee C18 is
26、 actively studying alternatives to deal with this issue.B Abrasion 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.C Not recommended for paving in areas subject to heavy foot traffic.C616/C616M 152
