Designation:C149203(Reapproved 2016)Standard Specification forConcrete Roof Tile1This standard is issued under the fixed designation C1492;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 concrete tiles intended for theuse as roof covering where durability and appearance arerequired to provide a weather-resistant surface of specifieddesign.1.2 Tiles are manufactured from portland cement,water,and mineral aggregates with or without the inclusion of othermaterials.1.3 Tiles are shaped during manufacturing by molding,pressing,or extrusion.The shaping method can be used todescribe the tile.1.4 Other constituents,such as chemical and mineral admix-tures established as suitable for use in concrete,shall conformto ASTM standard specifications where applicable,or shall beshown by tests or experience not to be detrimental to thedurability of concrete.1.5 Tiles are generally planar or undulating rectangularshapes available in a variety of cross-sectional areas profiles,shapes,sizes,surface textures,and colors.NOTE1Concrete roof tiles covered by this specification are madefrom lightweight or normal weight aggregates,or both.NOTE2When particular features are desired,such as color,surfacetexture for appearance,or other special features,such properties should bespecified by the purchaser.However.the local sellers should be consultedas to the availability of concrete roof tile having a desired feature.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:2C33 Specification for Concrete AggregatesC67 Test Methods for Sampling and Testing Brick andStructural Clay TileC90 Specification for Loadbearing Concrete Masonry UnitsC140 Test Methods for Sampling and Testing ConcreteMasonry Units and Related UnitsC150 Specification for Portland CementC260 Specification for Air-Entraining Admixtures for Con-creteC331 Specification for Lightweight Aggregates for ConcreteMasonry UnitsC494/C494M Specification for Chemical Admixtures forConcreteC595 Specification for Blended Hydraulic CementsC618 Specification for Coal Fly Ash and Raw or CalcinedNatural Pozzolan for Use in ConcreteC979 Specification for Pigments for Integrally Colored Con-creteC989 Specification for Slag Cement for Use in Concrete andMortarsC1157 Performance Specification for Hydraulic Cement3.Terminology3.1 DefinitionsThe following terms are used in connectionwith concrete roof tiles:3.2 batten lugsprotrusions on the underside of the tiledesigned to engage over the upper edge of tiling battens.3.3 head lapdistance of overlap measured from the up-permost course to the point that it laps over the undermostcourse.3.4 high profile tiletile with a rise to width ratio greaterthan 1:5.3.5 interlocking tiletiles with a system of ribs or groovesenabling the lateral joining of adjacent tiles in the samehorizontal row,with the overlapping lock covering the under-lapping lock.3.6 lengthmaximum overall dimension of the tile mea-sured parallel to the water course.3.7 low profile tiletile with a rise equal to or less than12in.3.8 medium profile tiletile with a rise greater than12in.and a rise-to-width ratio of less than or equal to 1:5.1This specification is under the jurisdiction of ASTM Committee C15 onManufactured Masonry Units and is the direct responsibility of SubcommitteeC15.06 on Roofing Tile.Current edition approved Dec.1,2016.Published December 2016.Originallypublished in 2001.Last previous edition approved in 2009 as C149201(2009).DOI:10.1520/C1492-03R16.2For 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 3.9 nail holesmall opening passing partially or totallythrough the tile to allow the penetration of a nail or screw forthe purpose of fastening the tile to a support.3.10 non-interlocking tiletiles that butt at the sides with-out lapping adjacent tiles.3.11 nose lugsprotrusion on the underside of the nose ofeach tile,contoured to fit into the main water courses of the tileimmediately below,inhibiting the entry of wind-driven rain.3.12 profilecontour of the top surface of the tile whenviewed from the nose end.3.13 risevertical distance from the underside of the battenlug to the highest point of the surface profile.3.14 side lapcontinuous longitudinal overlap of a tile onits neighbor.3.15 thicknessany vertical measure
