    1、Designation: C 568 08aStandard 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 () 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.Refer to Guides C 1242 and C 1528 for the appropriateselection and use of limestone dimension stone.1.2 Dimension limestone shall include stone that is sawed,cut, split, or otherwise finished or s

    4、haped and shall specificallyexclude molded, cast, or otherwise artificially aggregated unitsof composed fragments, and also crushed and broken stone.2.

Terminology3.1 DefinitionsAll definitions are in accordance with Ter-minology C119.4. Classification4.1 Dimension limestone shall

    7、be classified into three cat-egories, generally descriptive of those limestones having den-sities in approximate ranges, as follows:4.1.1 I (Low-Density)Limestone having a density rang-ing from 110 through 135 lb/ft3(1760 through 2160 kg/m3).4.1.2 II (Medium-Density)Limestone having a densitygreater

    8、 than 135 and not greater than 160 lb/ft3(2160 through2560 kg/m3).4.1.3 III (High-Density)Limestone having a densitygreater than 160 lb/ft3(2560 kg/m3).5. Physical Requirements5.1 Limestone supplied under this specification shall con-form to the physical requirements listed in Table 1.5.2 Limestone

    9、shall be sound, durable, and free of spalls,cracks, 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

    10、project, shall be established by controlsamples. Select representative samples by viewing a sufficientnumber of physical samples prior to production that show thecomplete range of variations in color and texture of thelimestone specified.6. Sampling6.1 Samples, if required, for testing to determine

    11、the char-acteristics and physical properties shall be representative of thelimestone to be used.7.

    21、e 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

    22、 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 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.C 568 08a2
