Designation:C12616Standard Specification forCeramic Glazed Structural Clay Facing Tile,Facing Brick,and Solid Masonry Units1This standard is issued under the fixed designation C126;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope*1.1 This specification covers structural clay load-bearingfacing tile and facing brick and other“solid masonry units”made from clay,shale,fire-clay,or mixtures thereof,with orwithout the addition of grog or other mixtures,having a finishconsisting of a ceramic glaze fused to the body at above1500F(655C)making them inseparable,excluding naturalsalt-glazed ware.Two grades,based on permissible variation inface dimensions,and two types are covered,as follows:1.1.1 Grade S(select),for use with comparatively narrowmortar joints.1.1.2 Grade SS(select sized or ground edge),for use wherevariation of face dimension must be very small.1.1.3 Type I(single-faced units),for general use where onlyone finished face will be exposed.1.1.4 Type II(two-faced units),for use where two oppositefinished faces will be exposed.1.2 The property requirements of this specification apply atthe time of purchase.The use of results from testing of brickand tile extracted from masonry structures for determiningconformance or nonconformance to the property requirements(Section 5)of this standard is beyond the scope of thisspecification.1.3 Brick and tile covered by this specification are manu-factured from clay,shale,or similar naturally occurring sub-stances and subjected to a heat treatment at elevated tempera-tures(firing).The heat treatment must develop sufficient firedbond between the particulate constituents to provide thestrength requirements of this specification.(See firing and firedbond in Terminology C1232.)1.4 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.1.5 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.1.6 The following precautionary caveat pertains only to thetest portion(Section 11.2)of this specification.This standarddoes not purport to address all of the safety concerns,if any,associated with its use.It is the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2.Referenced Documents2.1 ASTM Standards:2C67 Test Methods for Sampling and Testing Brick andStructural Clay TileC1232 Terminology of MasonryE84 Test Method for Surface Burning Characteristics ofBuilding MaterialsE2105 Practice for General Techniques of Thermogravimet-ric Analysis(TGA)Coupled With Infrared Analysis(TGA/IR)2.2 National Fire Protection Association Standard:3NFPA No.255 Test for Surface Burning Characteristics ofBuilding Materials2.3 Underwriters Laboratories,Inc.Standard:4UL No.723 Flammability Studies of Cellular Plastics andother Building Materials used for Interior Finishes3.Terminology3.1 DefinitionsFor definitions relating to ceramic glazedstructural clay facing tile,facing brick,and solid masonryunits,refer to Terminology C1232.1This 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 June 1,2016.Published July 2016.Originally approvedin 1936.Last previous edition approved in 2015 as C126 15.DOI:10.1520/C0126-16.2For 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.3Available from National Fire Protection Association(NFPA),1 BatterymarchPark,Quincy,MA 02169-7471,http:/www.nfpa.org.4Available from Underwriters Laboratories(UL),333 Pfingsten Rd.,Northbrook,IL 60062-2096,http:/.*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 4.Ordering Information4.1 Orders for material under this specification shall includethe following information:4.1.1 GradeWhen the grade is not specified,the require-ments for Grade S shall govern.4.1.2 TypeWhen the type is not specified,the require-ments for Type I shall govern.4.1.3 Sizes and ShapesThe sizes and shapes shall bespecified in accordance with Section 6.1.4.1.4 Color and Textu
