1、Designation: C 629 03Standard Specification forSlate Dimension Stone1This standard is issued under the fixed designation C 629; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indi
2、cates the year of last reapproval. Asuperscript epsilon (e) 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 requirements, a
3、nd sampling appropriate to the selec-tion of slate for general building and structural purposes.1.2 Dimension slate shall include stone that is sawed, cut,split, or otherwise finished or shaped, and shall specificallyexclude molded, cast, or otherwise artificially aggregated unitscomposed of fragmen
4、ts, and also crushed and broken stone.1.3 It specifically excludes roofing slate (see SpecificationC 406) and slate for industrial uses.2.

The new abrasive is currrently moreaggressive
20、, resulting in lower abrasive hardness values (Ha) than when the standard was initially established. As such, care should be taken when interpreting Havaluesfrom tests using the new abrasive, particularly with regard to currentASTM stone standard specification requirements for abrasion resistance, w
21、hich were developed whenthe original abrasive was still in use. Committee C-18 is actively studying alternatives to address this issue.CAbrasion Resistance Test Method C 1353 will eventually replace Test Method C 241 and it is not necessary to perform both tests. Availability of the proper equipmentand materials by the testing laboratory may determine which test is performed.C629032
