Designation:C108819Standard Specification forThin Veneer Brick Units Made From Clay or Shale1This standard is issued under the fixed designation C1088;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.Scope*1.1 This specification covers thin veneer brick units madefrom clay,shale,fire clay,sand,or mixtures thereof,and firedto incipient fusion for use in adhered or fastened veneerapplications.Three types of thin veneer brick units in each oftwo grades are covered.In this specification,the term thinveneer brick shall be understood to mean clay masonry unitwith a maximum thickness of 134in.(44.45 mm).1.2 The property requirements of this specification apply atthe time 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 7)of this specification is beyond the scope of thisspecification.1.3 The brick are prismatic units available in a variety ofsizes,textures,colors,and shapes.This specification is notintended to provide specifications for paving brick(see Speci-fication C902).1.4 Brick covered by this specification are manufacturedfrom clay,shale,or similar naturally occurring substances andsubjected to a heat treatment at elevated temperatures(firing).The heat treatment must develop sufficient fired bond betweenthe particulate constituents to provide the strength and dura-bility requirements of the specification.(See“firing”and“firedbond”in Terminology C1232.)1.5 Thin brick are shaped during manufacture by molding,pressing,or extrusion.The shaping method is a way to describethe thin brick.Thin brick may also be cut from thicker masonryunits.1.5.1 This standard and its individual requirements shall notbe used to qualify or corroborate the performance of a masonryunit made from other materials,or made with other formingmethods,or other means of binding the materials.1.6 The text of this specification references notes andfootnotes which provide explanatory material.These notes andfootnotes(excluding those in tables and figures)shall not beconsidered as requirements of the standard.1.7 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.1.8 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:2C67/C67M Test Methods for Sampling and Testing Brickand Structural Clay TileC902 Specification for Pedestrian and Light Traffic PavingBrickC1232 Terminology for Masonry3.Terminology3.1 DefinitionsFor definitions relating to thin veneerbrick,refer to Terminology C1232.4.Classification4.1 GradesGrades classify brick according to their resis-tance to damage by freezing and thawing when saturated at amoisture content not exceeding the 24-h cold water absorption.Two grades of thin veneer brick units are covered and therequirements are given in Section 7.4.1.1 Grade ExteriorBrick intended for use where highresistance to damage caused by cyclic freezing and thawing isdesired.4.1.2 Grade InteriorBrick intended for use where moder-ate resistance to cyclic freezing and thawing damage ispermissible.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 March 1,2019.Published March 2019.Originallyapproved in 1988.Last previous edition approved in 2018 as C1088 18.DOI:10.1520/C1088-19.2For 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.*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 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 4.2 Three types of thin veneer brick units are covered asfollows:4.2.1 Type TBS(Standard)Thin veneer brick for generaluse in masonry.4.2.2 Type TBX(Select)Thin veneer brick for general u
