1、Designation: C1526 08 (Reapproved 2014)Standard Specification forSerpentine Dimension Stone1This standard is issued under the fixed designation C1526; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A num
2、ber in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 (s
3、erpentine marble) for general building andstructural purposes. Refer to Guides C1242 and C1528 for theappropriate selection and use of serpentine dimension stone.1.2 Dimension serpentine shall include stone that is sawed,cut, split, or otherwise finished or shaped and shall specificallyexclude molde
4、d, cast, or otherwise artificially aggregated unitscomposed of fragments, and also crushed and broken stone.2.

7、sical 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 absorptio
8、nis 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 from o
9、ccurring 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 mineral
10、 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. Representative
11、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.5. Sampling5.1 Samples, if required, for testing to determine the char-acteristics and physical properties shall be represe

Where two or more stone varieties are combined forcolor and design effects, there should be no
22、 greater difference than five points inabrasion 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 values (Ha) thanwhen the sta
23、ndard was initially established. 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 abrasive was still in use.CIt is not necessary to perform both tests.Availability of the proper equipment andmaterials by the testing laboratory may determine which test is performed.C1526 08 (2014)2
