1、Designation: C629/C629M 10C629/C629M 15Standard Specification forSlate Dimension Stone1This standard is issued under the fixed designation C629/C629M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A num
2、ber 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 ofslate for gener
3、al building and structural purposes. Refer to Guides C1242 and C1528 for the appropriate selection and use of slatedimension stone.1.2 Dimension slate shall include stone that is sawed, cut, split, or otherwise finished or shaped, and shall specifically excludemolded, cast, or otherwise artificially
4、 aggregated units composed of fragments, and also crushed and broken stone.1.3 It specifically excludes roofing slate (see Specification C406/C406M) and slate for industrial uses.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated
5、 in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2.

24、8S has been changed. The new abrasive is currrently moreaggressive, resulting in lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Ha valuesfrom tests using the new abrasive, particularly with regard to currentASTM s
25、tone standard specification requirements for abrasion resistance, which were developed whenthe original abrasive was still in use. Committee C18 is actively studying alternatives to address 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.C629/C629M 152
