1、Designation: C 1526 03Standard Specification forSerpentine Dimension Stone1This standard is issued under the fixed designation C 1526; 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 parenthes
2、es indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers the material characteristics,physical requirements, and sampling appropriate for the selec-tion of serpentine (serpentine marbl
3、e) for general building andstructural purposes.1.2 Dimension serpentine shall include stone that is sawed,cut, split, or otherwise finished or shaped and shall specificallyexclude molded, cast, or otherwise artificially aggregated unitscomposed of fragments, and also crushed and broken stone.2.

6、4. Physical Properties4.1 Serpentine supplied under this specification shall con-form to the physical requirements prescribed in Table 1.4.2 Serpentine shall be free of minerals that may causeobjectionable staining under normal environments of use.4.3 Warping of serpentine due to localized water ab
7、sorptionis a natural characteristic of the material and shall be taken intoaccount in assessing the permissible natural variations suitablefor a particular application. Setting serpentine with a non-water-based setting material in a full-coverage setting bed overa rigid substrate can prevent warping
8、 from occurring afterinstallation.4.4 Alteration of the color and finish of serpentine withexposure to the weather can occur and shall be taken intoaccount in assessing the suitability of serpentine for a particularapplication. Alteration of serpentine, due to weather exposure,can result in whitish
9、mineral deposits on the surface of thestone and can also result in a faded appearance and loss ofpolish.4.5 The desired color and texture, with their permissiblenatural variations in material characteristics for material to beproduced for the project, shall be established by controlsamples. Represen
10、tative samples shall be selected prior toproduction by viewing a sufficient number of samples thatshow the complete range of variations in color and texture ofthe serpentine specified.1This specification is under the jurisdiction of ASTM Committee C18 onDimension Stone and is the direct responsibili

15、ffects, there should be no greater difference than five pointsin abrasion resistance.BThe supplier of the No. 60 Alundum abrasive, Norton, has indicated that theformula for Norton treatment 138S has been changed. The new abrasive iscurrently more aggressive, resulting in lower abrasion resistance va

As such, care should be taken wheninterpreting Havalues from tests using the new abrasive, particularly with regard tocurrent ASTM stone standard specification requirements for abrasion resistance,which were developed when the original abras
