Designation:F262013Standard Practice forHeat Fusion Joining of Polyethylene Pipe and Fittings1This standard is issued under the fixed designation F2620;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.Scope*1.1 This practice describes procedures for making jointswith polyethylene(PE)pipe and fittings by means of heatfusion joining in,but not limited to,a field environment.Othersuitable heat fusion joining procedures are available fromvarious sources including pipe and fitting manufacturers.Thisstandard does not purport to address all possible heat fusionjoining procedures,or to preclude the use of qualified proce-dures developed by other parties that have been proved toproduce reliable heat fusion joints.1.2 The parameters and procedures are applicable only tojoining polyethylene pipe and fittings of related polymerchemistry.They are intended for PE fuel gas pipe per Speci-fication D2513 and PE potable water,sewer and industrial pipemanufactured per Specification F714,Specification D3035,and AWWA C901 and C906.Consult with the pipe manufac-turers to make sure they approve this procedure for the pipe tobe joined(see Appendix X1).NOTE1Information about polyethylene pipe and fittings that haverelated polymer chemistry is presented in Plastics Pipe Institute(PPI)TR-33 and TR-41.1.3 Parts that are within the dimensional tolerances given inpresent ASTM specifications are required to produce soundjoints between polyethylene pipe and fittings when using thejoining techniques described in this practice.1.4 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.1.5 The text of this practice references notes,footnotes,andappendixes which provide explanatory material.These notesand footnotes(excluding those in tables and figures)shall notbe considered as requirements of the practice.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.2.Referenced Documents2.1 ASTM Standards:2D2513 Specification for Polyethylene(PE)Gas PressurePipe,Tubing,and FittingsD3035 Specification for Polyethylene(PE)Plastic Pipe(DR-PR)Based on Controlled Outside DiameterF714 Specification for Polyethylene(PE)Plastic Pipe(DR-PR)Based on Outside DiameterF1056 Specification for Socket Fusion Tools for Use inSocket Fusion Joining Polyethylene Pipe or Tubing andFittings2.2 PPI Documents:TR-33 Generic Butt Fusion Joining Procedure for FieldJoining of Polyethylene3TR-41 Generic Saddle Fusion Joining Procedure for Poly-ethylene Gas Piping32.3 AWWA Documents:AWWA C901 Standard for Polyethylene(PE)Pressure Pipeand Tubing,12in.(13 mm)through 3 in.(76 mm),forWater Service4AWWA C906 Standard for Polyethylene(PE)Pressure Pipeand Fittings,4 in.(100 mm)through 63 in.(1575 mm),forWater Distribution and Transmission43.Summary of Practice3.1 The principle of heat fusion joining of polyethylene(PE)pipe is to heat two prepared surfaces to a designatedtemperature,then fuse them together by application of asufficient force.This force causes the melted materials to flowand mix,thereby resulting in fusion.3.2 The heat-fusion procedures covered in this practice aresocket fusion,butt fusion,and saddle fusion.1This practice is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.20 on Joining.Current edition approved Nov.1,2013.Published January 2014.Originallyapproved in 2006.Last previous edition approved in 2012 as F2620 12.DOI:10.1520/F2620-13.2For 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 Plastics Pipe Institute(PPI),105 Decker Court,Suite 825,Irving,TX 75062,http:/www.plasticpipe.org.4Available from American Water Works Association(AWWA),6666 W.QuincyAve.,Denver,CO 80235,http:/www.awwa.org.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.2.1 Procedure 1,Socket FusionThe socket-fusion pro-cedure involves simultaneously heating the outside surface ofa pipe end and the inside of a fitting socket,which is sized tobe smaller than the smallest outside diameter of the pipe.Afterthe proper melt has been generated at each face to be mated,the two components are joi
