Designation:F311014Standard Practice forProper Use of Mechanical Trenchless Point Repair Sleevewith Locking Gear Mechanism for Pipes of Varying InnerDiameter and Offset Joints1This standard is issued under the fixed designation F3110;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 practice establishes minimum requirements forgood practices for the materials and installation of mechanicaltrenchless repair sleeve with a locking gear mechanism forpipes of varying inner diameter and offset joints in the range of6 to 72 in.(150 to 1800 mm).1.2 This practice applies to storm,potable water,wastewaterand industrial pipes,conduits and drainage culverts.1.3 When the specified materials are used in manufacturingthe sleeve and installed in accordance with this practice,thesleeve shall extend over a predetermined length of the host pipeas a continuous,tight fitting,corrosion resistant and verifiablenon-leaking pipe repaired using one or more pieces of therepair sleeve mechanism.The maximum internal pressure thissleeve can carry depends on the diameter and the wallthickness,ranging from 10 to 15 bars;the external pressureshall not exceed 1.5 bars.1.4 All materials in contact with potable water shall becertified to meet NSF/ANSI 61/372.1.5 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 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.Particular attentionis drawn to those safety regulations and requirements involvingentering into and working in confined spaces.2.Referenced Documents2.1 ASTM Standards:2A240 Specification for Chromium and Chromium-NickelStainless Steel Plate,Sheet,and Strip for Pressure Vesselsand for General ApplicationsA666 Specification for Annealed or Cold-Worked AusteniticStainless Steel Sheet,Strip,Plate,and Flat Bar2.2 NASSCO Guidelines:3Specifications for Sewer Collection System Rehabilitation2.3 European Standard:4EN 681-1 Elastomeric sealsMaterials requirement for pipejoint seals used in water and drainage applicationsPart1:Vulcanized rubber2.4 NSF/ANSI Standards:5NSF/ANSI 61 Drinking water system componentsNSF/ANSI 372 Drinking water system components3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 access point,nupstream or downstream locationsthat serve as the point of entry or exit for the point repair of theexisting pipe.3.1.2 bladder,nan apparatus,when pressurized,inflates atube that presses against the inner pipe walls.3.1.3 EPDM rubber,nethylene propylene diene monomerrubber formed to yield wide ranging engineering propertiesusing a synthetic process.1This practice is under the jurisdiction of ASTM Committee F36 on Technologyand Underground Utilities and is the direct responsibility of Subcommittee F36.20on Inspection and Renewal of Water and Wastewater Infrastructure.Current edition approved Nov.15,2014.Published January 2015.DOI:10.1520/F3110-14.2For 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 Association of Sewer Service Companies(NASSCO),2470 Longstone Lane,Suite M,Marriottsville,MD 21104,http:/nassco.org.4Available from European Committee for Standardization(CEN),AvenueMarnix 17,B-1000,Brussels,Belgium,http:/www.cen.eu.5Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.1.4 finished thickness,nthe finished sleeve thicknessafter installation.3.1.5 hydrophilic,na material that is moisture activatedwith expansion characteristics of 58 times its original thick-ness.3.1.6 locking gear,ngears that alter the diameter of thesleeve that can be locked to retain a desired diameter for thesleeve when put into service.3.1.7 NBR,nnitrile butadiene rubber.3.1.8 offset joints,njoints with defects from the inner borearea not aligning perfectly.3.1.9 packer,nan inflatable bladder device on wheels thattransports a sleeve through the pipe and further inflates/expands for final sleeve installation.3.1.10 point repair,nrepair of a local defect withoutrelining damaged pipe,conduit or culvert from one manhole tothe next.3.1.11 resin,nsynthetic fluid that hardens
