This specification covers electrofusion-type polyethylene fittings for outside diameter controlled polyethylene pipe and tubing. Specimens shall be conditioned prior to joining at the minimum or maximum pipe temperature allowable for fusion. The fittings shall be subjected to several tests to determine conformance to minimum hydraulic burst pressure, sustained pressure, tensile strength, impact resistance, and joint integrity requirements. Fusion evaluation test for fitting failure and evaluation for voids shall also be conducted.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers electrofusion polyethylene fittings for use with outside diameter-controlled polyethylene pipe, covered by Specifications D2447, D2513, D2737, D3035, and F714 and crosslinked polyethylene (PEX), covered by Specification F2788. Requirements for materials, workmanship, and testing performance are included. All requirements for joining PE electrofusion fittings to PE pipe shall also apply to joining PE electrofusion fittings to PEX pipe. Where applicable in this specification “pipe” shall mean “pipe” or “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 The following safety hazards caveat pertains only to the test method portion, Section 9, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
