Standard Specification for Socket Fusion Tools for Use in Socket Fusion Joining Polyethylene Pipe or Tubing and Fittings
ABSTRACT
This specification covers socket fusion tools for use in making socket fusion joints between polyethylene pipe or tubing and fittings as specified by certain specifications. It covers newly manufactured heater faces and used heater faces which have been recoated. Heater faces may be manufactured from aluminum, steel, or other suitable heat conducting material. The manufacture of these socket fusion tools shall be in accordance with good commercial practice so as to produce socket fusion tools meeting the requirements specified. Heater faces shall have surfaces free of cracks, voids, foreign inclusions, or injurious defects.
SCOPE
1.1 This specification covers socket fusion tools for use in making socket fusion joints between polyethylene pipe or tubing and fittings as specified by Specifications D3035, D2513, and D2683. This specification covers newly manufactured heater faces and used heater faces which have been recoated. Requirements for materials, workmanship, and dimensions are included. Where applicable on this specification, “pipe” shall mean “pipe” and “tubing.”
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

sticking may be minimized by covering the heating surfaces with a
stick-resistant coating such as polytetrafluoroethylene (PTFE) or polyphe-
nylene sulfide (PPS). Copper or copper alloys are not suitable without
coating because some polyolefins react with copper.

A
Dimensions are for heater faces at the commonly used operating temperature of 500 °F (260 °C) (see AnnexA1 for dimensions for coated, aluminum heater faces at
73.4 °F (23 °C )).
B
Recommended heater faces should be manufactured close to maximum diameter for fitting heater faces and close to minimum diameter for pipe heater faces to allow
for wear and recoating.
C
Minimum dimensions have zero negative tolerance. Maximum dimensions have zero positive tolerance. The sketches and designs of the heater faces are illustrative
only. Entrance and base chamfer or radius is optional. The maximum entrance and base chamfer or radius is 0.03 in. (0.7 mm).
