Designation:C1208/C1208M16aStandard Specification forVitrified Clay Pipe and Joints for Use in Microtunneling,Sliplining,Pipe Bursting,and Tunnels1This standard is issued under the fixed designation C1208/C1208M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification establishes the criteria for themanufacture,quality assurance testing,inspection,installation,field acceptance testing,and product marking of vitrified clayjacking pipe to be used in microtunneling,the pilot tubemethod,sliplining,pipe bursting,and in casings and tunnels forthe conveyance of sewage,industrial wastes,and storm water.1.1.1 Sections 3 through 7 and 9 of this specification containmanufacturing,quality assurance testing,inspection,and prod-uct marking criteria which are applicable to vitrified clay pipeprior to installation.1.1.2 Section 8 of this specification contains criteria for theinstallation and field acceptance testing of vitrified clay pipe.1.2 This specification also covers materials and test require-ments for jointing of the pipe.1.3 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C67 Test Methods for Sampling and Testing Brick andStructural Clay TileC301 Test Methods for Vitrified Clay PipeC828 Test Method for Low-Pressure Air Test of VitrifiedClay Pipe LinesC896 Terminology Relating to Clay ProductsC1091 Test Method for Hydrostatic Infiltration Testing ofVitrified Clay Pipe LinesD395 Test Methods for Rubber PropertyCompression SetD412 Test Methods for Vulcanized Rubber and Thermoplas-tic ElastomersTensionD471 Test Method for Rubber PropertyEffect of LiquidsD518 Test Method for Rubber DeteriorationSurfaceCracking(Withdrawn 2007)3D543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD573 Test Method for RubberDeterioration in an AirOvenD1149 Test Methods for Rubber DeteriorationCracking inan Ozone Controlled EnvironmentD2240 Test Method for Rubber PropertyDurometer Hard-ness3.Terminology3.1 DefinitionsTerminology C896 can be used for clarifi-cation of terminology in this specification.PIPE4.Materials and Manufacture4.1 Vitrified clay pipe shall be manufactured from fire clay,shale,surface clay,or a combination of these materials that,when formed into pipe and fired to suitable temperatures,yields a product that conforms to this specification.4.2 Test Requirements for Pipe:4.2.1 Test Samples:4.2.1.1 When requested,test samples representative of thepipe to be used shall be selected by the purchaser or hisrepresentative from the suppliers stock.4.2.1.2 The number of samples to be tested shall not exceed0.5%of the number of pipe of each size furnished,except thatno less than three samples shall be tested.1This specification is under the jurisdiction of ASTM Committee C04 onVitrified Clay Pipe and is the direct responsibility of Subcommittee C04.20 onMethods of Test and Specifications.Current edition approved Nov.1,2016.Published December 2016.Originallyapproved in 1991.Last previous edition approved in 2016 as C1208/C1208M-16.DOI:10.1520/C1208_C1208M-16A.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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.2.1.3 If any of the test samples fail to meet the require-ments of 4.2.2 through 4.2.5,the manufacturer will be allowedto retest two additional samples representative of the originalmaterial for each one that failed.The pipe will be acceptable ifall retest samples meet the test requirements.If any of there-test pipe fail,the lot shall be rejected.4.2.1.4 If,subsequent to an initial test failure,the accuracyof the testing equipment is questioned,at the request of themanufacturer,the equipment shall be recalibrated and a retestmade or a retest made using other equipment of knownaccuracy.4.2.2 Bearing Strength:4.2.2.1 Pipe shall meet the bearing strength requirements ofTable 1 or Table 2.4.2.2.2 The manuf
