Designation:C152619Standard 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 number 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(serpentine 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 molded,cast,or otherwise artificially aggregated unitscomposed of fragments,and also crushed and broken stone.1.3 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C97/C97M Test Methods for Absorption and Bulk SpecificGravity of Dimension StoneC99/C99M Test Method for Modulus of Rupture of Dimen-sion StoneC119 Terminology Relating to Dimension StoneC170/C170M Test Method for Compressive Strength ofDimension StoneC241/C241M Test Method for Abrasion Resistance of StoneSubjected to Foot TrafficC880/C880M Test Method for Flexural Strength of Dimen-sion StoneC1242 Guide for Selection,Design,and Installation ofDimension Stone Attachment SystemsC1353 Test Method for Abrasion Resistance of DimensionStone Subjected to Foot Traffic Using a Rotary PlatformAbraserC1528 Guide for Selection of Dimension Stone3.Terminology3.1 DefinitionsAll definitions are in accordance with Ter-minology C119.4.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 absorptionis 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 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 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.Representative 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 representative of theserpentine to be used.6.Keywords6.1 serpentine;serpentine marble1This 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 Feb.1,2019.Published March 2019.Originallyapproved in 2002.Last previous edition approved in 2014 as C1526 08(2014).DOI:10.1520/C1526-19.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentionedin this standard.Users of this standard are expressly advised that determination of the validity of any such patent rights,and the riskof infringement of such rights,are entirely their own responsibility.This standard is subject to revision at any ti
