Designation:C1821/C1821M16Standard Practice forInstallation of Underground Circular Precast ConcreteManhole Structures1This standard is issued under the fixed designation C1821/C1821M;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 practice covers the procedures to be followed in theplanning,site preparation,installation,testing and backfillingof underground vertical reinforced circular precast concretemanholes and components manufactured in accordance withSpecification C478(C478M)and used in sewer,drainage,andwater works.1.2 Concrete pipe and box culverts are not covered underthis practice.Also,precast concrete utility structures covered inSpecification C858 are excluded from this practice.1.3 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in non-conformance with 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:2C443 Specification for Joints for Concrete Pipe andManholes,Using Rubber GasketsC443M Specification for Joints for Concrete Pipe andManholes,Using Rubber Gaskets(Metric)C478 Specification for Circular Precast Reinforced ConcreteManhole SectionsC478M Specification for Circular Precast Reinforced Con-crete Manhole Sections(Metric)C822 Terminology Relating to Concrete Pipe and RelatedProductsC858 Specification for Underground Precast Concrete Util-ity StructuresC881/C881M Specification for Epoxy-Resin-Base BondingSystems for ConcreteC923 Specification for Resilient Connectors Between Rein-forced Concrete Manhole Structures,Pipes,and LateralsC923M Specification for Resilient Connectors Between Re-inforced Concrete Manhole Structures,Pipes,and Laterals(Metric)C928/C928M Specification for Packaged,Dry,Rapid-Hardening Cementitious Materials for Concrete RepairsC969 Practice for Infiltration and Exfiltration AcceptanceTesting of Installed Precast Concrete Pipe Sewer LinesC969M Practice for Infiltration and Exfiltration AcceptanceTesting of Installed Precast Concrete Pipe Sewer Lines(Metric)C990 Specification for Joints for Concrete Pipe,Manholes,and Precast Box Sections Using Preformed Flexible JointSealantsC990M SpecificationforJointsforConcretePipe,Manholes,and Precast Box Sections Using PreformedFlexible Joint Sealants(Metric)C1107/C1107M Specification for Packaged Dry,Hydraulic-Cement Grout(Nonshrink)C1244 Test Method for Concrete Sewer Manholes by theNegative Air Pressure(Vacuum)Test Prior to BackfillC1244M Test Method for Concrete Sewer Manholes by theNegative Air Pressure(Vacuum)Test Prior to Backfill(Metric)C1478 Specification for Storm Drain Resilient ConnectorsBetween Reinforced Concrete Storm Sewer Structures,Pipes,and LateralsC1478M Specification for Storm Drain Resilient ConnectorsBetween Reinforced Concrete Storm Sewer Structures,Pipes,and Laterals(Metric)D2487 Practice for Classification of Soils for EngineeringPurposes(Unified Soil Classification System)D2488 Practice for Description and Identification of Soils(Visual-Manual Procedure)1This test method is under the jurisdiction of ASTM Committee C13 onConcrete Pipe and is the direct responsibility of Subcommittee C13.06 on Manholesand Specials.Current edition approved Feb.15,2016.Published March 2016.DOI:10.1520/C1821_C1821M162For 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 F2510/F2510M Specification for Resilient Connectors Be-tween Reinforced Concrete Manhole Structures and Cor-rugated High Density Polyethylene Drainage Pipes2.2 AASHTO Standard:AASHTO M145 Classification of Soils and Soil-AggregateMixtures for Highway Construction Purposes32.3 Federal Standard:29 CFR Part 1926 Safety and Health Regulations for Con-struction43.Terminology3.1 DefinitionsFor definitions of terms relating to concretemanholes,see Terminology C822.For terminology related tosoil classifications,see Practices D2487 and D2488.3.2 engineer,nowners representative,either designer ofrecord or inspector,with responsible charge of the ownersinterest during the installation phase of construction.3.3 installer,nprime co
