ASTM C1526-2008 Standard Specification for Serpentine Dimension Stone《蛇纹岩规格石料标》.pdf

1、Designation: C 1526 08Standard 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. Refer to Guides C 1242 and C 1528 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 molded, cast, or o

Terminology3.1 DefinitionsAll definitions are in accordance with Ter-minology C119.4. Physical Properties4.1 Serpentine supplie

7、d 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 absorptionis a natural characteristic of the ma

8、terial 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 occurring afterinstallation.4.4 Alterat

9、ion 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 deposits on the surface of thestone a

10、nd 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 samples shall be selected prior toprod

11、uction 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 representative of theserpentine to be used.6.

Where two or more stone varieties are combinedfor color and design effects, 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 abrasiv

22、e iscurrently more aggressive, resulting in lower abrasion resistance values (Ha) thanwhen the standard 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 equipmentand materials by the testing laboratory may determine which test is performed.C1526082
