Designation:C6213aStandard Specification forBuilding Brick(Solid Masonry Units Made From Clay orShale)1This standard is issued under the fixed designation C62;the number immediately following the designation indicates the year of originaladoption or,in the case of revision,the year of last revision.Anumber in parentheses indicates the year of last reapproval.Asuperscriptepsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers brick intended for both struc-tural and nonstructural masonry where external appearance isnot a requirement.The brick are prismatic units available in avariety of sizes,shapes,textures,and colors.The specificationdoes not cover brick intended for use as facing units or wheresurface appearance is a requirement.If brick are required tohave a particular color,texture,finish,uniformity,or limits oncracks,warpage,or other imperfections detracting from theappearance they are purchased under Specification C216.Thisspecification does not cover brick intended for use as pavingbrick(see Specification C902).1.2 The property requirements of this standard apply at thetime of purchase.The use of results from testing of brickextracted from masonry structures for determining confor-mance or nonconformance to the property requirements(Sec-tion 4)of this standard is beyond the scope of this standard.1.3 Brick are manufactured from clay,shale,or similarnaturally occurring earthy substances and subjected to a heattreatment at elevated temperatures(firing).The heat treatmentmust develop sufficient fired bond between the particulateconstituents to provide the strength and durability requirementsof this specification(see Terminology C1232).1.4 Brick are shaped during manufacture by molding,pressing,or extrusion,and the shaping method is a way todescribe the brick.1.5 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.1.6 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.2.Referenced Documents2.1 ASTM Standards:2C67 Test Methods for Sampling and Testing Brick andStructural Clay TileC216 Specification for Facing Brick(Solid Masonry UnitsMade from Clay or Shale)C902 Specification for Pedestrian and Light Traffic PavingBrickC1232 Terminology of Masonry3.Terminology3.1 DefinitionsFor definitions relating to building brick,refer to Terminology C1232.4.Classification4.1 Grades classify brick according to their resistance todamage by freezing when wet,as defined in Note 1.Threegrades are covered and the grade requirements are shown inTable 1.4.1.1 Grade SW(Severe Weathering)Brick intended foruse where high and uniform resistance to damage caused bycyclic freezing is desired and where the brick may be frozenwhen saturated with water.4.1.2 Grade MW(Moderate Weathering)Brick intendedfor use where moderate resistance to cyclic freezing damage ispermissible or where the brick may be damp but not saturatedwith water when freezing occurs.4.1.3 Grade NW(Negligible Weathering)Brick with littleresistance to cyclic freezing damage but which are acceptablefor applications protected from water absorption and freezing.NOTE1The word“saturated,”with respect to this standard,refers tothe condition of a brick that has absorbed water to an amount equal to thatresulting from submersion in room temperature water for 24 h.1This specification is under the jurisdiction of ASTM Committee C15 onManufactured Masonry Units and is the direct responsibility of SubcommitteeC15.02 on Brick and Structural Clay Tile.Current edition approved Dec.1,2013.Published December 2013.Originallyapproved in 1927.Last previous edition approved in 2013 as C62 13.DOI:10.1520/C0062-13A.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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.Physical Properties5.1 DurabilityWhen Grade is not specified,the require-ments for Grade SW shall govern.5.1.1 Physical Property RequirementsThe brick shall con-form to the physical requirements for the Grade specified asprescribed in Table 1.For the compressive strength require-ments in Table 1,test the unit with the compressive forceperpendicular to the bed surface of the unit,with the unit in thestretcher position.5.1.2 Absorption AlternateThe saturation coefficient re-quirement does not apply,provided that the 24-h cold wa
