    1、Designation: C 568 03Standard Specification forLimestone Dimension Stone1This standard is issued under the fixed designation C 568; 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

    2、indicates 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 requirement

    3、s, and sampling appropriate to the selec-tion of limestone for general building and structural purposes.1.2 Dimension limestone shall include stone that is sawed,cut, split, or otherwise finished or shaped and shall specificallyexclude molded, cast, or otherwise artificially aggregated unitsof compo

Physical Requirements5.1 Limestone supplied under this specification shall con-form to the physical requirements listed in Table 1.5.2 Limestone shall be sound, durable, and free of spalls,cracks,

    9、 open seams, pits, or other defects that are likely toimpair its structural integrity in its intended use.5.3 The desired color and texture, with their permissiblenatural variations in material characteristics for all material tobe produced for the project, shall be established by controlsamples.

    11、be representative of thelimestone to be used.1This specification is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibility of Subcommittee C18.03 onMaterial Specifications.Current edition approved Dec. 1, 2003.

    21、ula 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 when interpreting Havaluesfrom tests using the new abrasive, particularly wi

    22、th regard to current ASTM stone standard specification requirements for abrasion resistance, which 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.C568032
