Designation:C41215Standard Specification forConcrete Drain Tile1This standard is issued under the fixed designation C412;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.Scope1.1 This specification covers concrete drain tile with inter-nal diameters from 4 to 36 in.that are intended to be used forsurface and subsurface drainage.1.2 Acomplete metric companion to Specification C412 hasbeen developedC412M;therefore,no metric equivalents arepresented in this specification.NOTE1This specification is a manufacturing and purchase specifica-tion only and does not include requirements for bedding,backfill,or therelationship between field load condition and the strength classification ofdrain tile.However,experience has shown that the successful performanceof the product depends upon the proper selection of the class of drain tile,type of bedding and backfill,and care that the installation conforms to theconstruction specifications.The owner is cautioned that he must correlatethe field requirements with the class of drain tile specified and provide foror require inspection at the construction site.2.Referenced Documents2.1 ASTM Standards:2C33/C33M Specification for Concrete AggregatesC150/C150M Specification for Portland CementC260/C260M Specification for Air-Entraining Admixturesfor ConcreteC494/C494M Specification for Chemical Admixtures forConcreteC497 Test Methods for Concrete Pipe,Manhole Sections,orTileC595/C595M Specification for Blended Hydraulic CementsC618 Specification for Coal Fly Ash and Raw or CalcinedNatural Pozzolan for Use in ConcreteC822 Terminology Relating to Concrete Pipe and RelatedProductsC989/C989M Specification for Slag Cement for Use inConcrete and MortarsC1017/C1017M Specification for Chemical Admixtures forUse in Producing Flowing ConcreteC1116/C1116M Specification for Fiber-Reinforced ConcreteC1602/C1602M Specification for Mixing Water Used in theProduction of Hydraulic Cement Concrete3.Terminology3.1 DefinitionsFor definitions of terms relating to concretepipe,see Terminology C822.4.Classification4.1 Drain tile manufactured according to this specificationshall be of the following four classes:4.1.1 Standard-Quality Concrete Drain Tile,intended forland drainage of ordinary soils where the tile are laid intrenches of moderate depths and widths.Standard-Qualityconcrete drain tile are not recommended for use where internaldiameters in excess of 12 in.are required.4.1.2 Extra-Quality Concrete Drain Tile,intended for landdrainage of ordinary soils where the tile are laid in trenches ofconsiderable depths or widths,or both.4.1.3 Heavy-Duty Extra-Quality Concrete Drain Tile,in-tended for land drainage of ordinary soils where the tile are laidin trenches of large depths or widths,or both.4.1.4 Special-Quality Concrete Drain Tile,intended for landdrainage where special precautions are necessary for concretetile laid in soils that are markedly acid or contain unusualquantities of sulfates(see Section 7),and where the tile are laidin trenches of considerable depths or widths,or both.4.1.4.1 Where the calculated loads are in excess of thecrushing strengths prescribed in the physical requirements forextra-quality and special-quality concrete drain tile,tilestrengths must be specified in advance by the owner.5.Basis of Acceptance5.1 The acceptability of drain tile shall be determined by(1)the results of the physical tests as specified in Section 8,and inTest Methods C497,(2)measurements and inspection toascertain whether the tile conform to the requirements regard-ing dimensions,shape,and freedom from visible defects,and(3)the manufacturers certification in writing that the tile have1This specification is under the jurisdiction of ASTM Committee C13 onConcrete Pipe and is the direct responsibility of Subcommittee C13.01 onNon-Reinforced Concrete Sewer,Drain and Irrigation Pipe.Current edition approved Oct.1,2015.Published October 2015.Originallyapproved in 1958.Last previous edition approved in 2011 as C412 11.DOI:10.1520/C0412-15.2For 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 been made in accordance with any special provisions,such asstrength,absorption,permeability,type of cement,admixture,curing conditions,etc.5.2 The owner shall specify in writing the class or classes ofconcrete tile to be supplied,whether Standard-Quality,Extra-Quality,Heavy-Duty Extra-Quality,or Special-Quality.Un
