1、Designation: C629/C629M 10Standard 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 number in parent
2、heses 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 requir
3、ements, and sampling appropriate to the selec-tion of slate for general building and structural purposes. Referto Guides C1242 and C1528 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, an
4、d shall specificallyexclude molded, cast, or otherwise artificially aggregated unitscomposed of fragments, and also crushed and broken stone.1.3 It specifically excludes roofing slate (see SpecificationC406/C406M) and slate for industrial uses.1.4 The values stated in either SI units or inch-pound u
5、nitsare to be regarded separately as standard. The values 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:2

22、 supplier of the No. 60Alundum abrasive, Norton, has indicated that the formula for Norton treatment 138S 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
23、when interpreting Havaluesfrom tests using the new abrasive, particularly with regard to currentASTM stone 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.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.C629/C629M 102
