2、cates the year of last reapproval. Asuperscript 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 requirements, an
3、d sampling appropriate to the selec-tion of slate for general building and structural purposes. Referto Guides C 1242 and C 1528 for the appropriate selection anduse of slate dimension stone.1.2 Dimension slate shall include stone that is sawed, cut,split, or otherwise finished or shaped, and shall
4、specificallyexclude molded, cast, or otherwise artificially aggregated unitscomposed of fragments, 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, resulting in
21、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, which were devel
22、oped whenthe original abrasive was still in use. Committee C18 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.C629082
