1、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 numbe
2、r 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
3、,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
4、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 pipemanufac
