Designation:C503/C503M15Standard Specification forMarble Dimension Stone1This standard is issued under the fixed designation C503/C503M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript 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 to the selec-tion of marble for general building and structural purposes.Refer to Guides C1242 and C1528 for the appropriate selectionand use of marble dimension stone.1.2 Dimension marble shall include stone that is sawed,cut,split,or otherwise finished or shaped into blocks,slabs or tiles,and shall specifically exclude molded,cast and artificiallyaggregated units composed of fragments,and also crushed andbroken stone.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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.Classification4.1 Dimension marble is classified as follows:4.1.1 I Calcite.4.1.2 II Dolomite.NOTE1See Terminology C119 for definitions of calcite and dolomite.5.Soundness5.1 Marbles are further classified into four“Soundness”groups:A,B,C,and D.Classifications are based on theproperties encountered in fabrication and has no referencewhatsoever to comparative merit or value.Marble is classifiedby its producer.5.2 The Soundness classifications indicate what repairs maybe necessary prior to or during installation,based on standardtrade practices.5.3 The groupings A,B,C,and D,should be taken intoaccount when specifying marble,for all marbles are notsuitable for all building applications.This is particularly true ofthe comparatively fragile marbles classified under SoundnessGroups C and D,which may need additional fabrication beforeor during installation.Only Soundness Group A marble shouldbe used for exterior installations,or any applications thatrequire the stone panel to resist lateral loads or to bear weightwithout reinforcement.5.3.1 The four groups are:1This 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 Dec.1,2015.Published January 2016.Originallyapproved in 1962.Last previous edition approved in 2010 as C503/C503M 10.DOI:10.1520/C0503_C0503M-15.2For 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 States1 Group ASound marbles with uniform and favorableworking qualities;containing no geological flaws,voids,spalls,cracks,open seams,pits or other defects.Group B Marble similar in soundness to Group A,butwith less favorable working qualities;may have some minorsmall holes or voids that may require a limited amount of oneor more of the following:waxing3,sticking4,and filling5.Group CMarble with some variations in working quali-ties;geological flaws,voids,and lines of separation arecommon.It is standard practice to repair these variations byone or more of the following methods:waxing3,sticking4,filling5,cementing,or other forms of additional reinforcement.Group D Marbles similar in soundness to Group C,butcontaining a larger proportion of natural faults,maximumvariations in working qualities,and requiring more of the samemethods of finishing.66.Physical Properties6.1 Marble supplied under this specification shall conformto the physical requirements prescribed in Table 1.6.2 Marble for exterior dimension use shall be SoundnessGroupAstone,free of spalls,cracks,open seams,pits,or otherdefects that are likely to impair its structural integrity in itsintended use.6.3 Marble for interior use may
