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.

1.1 This specification covers electrofusion polyethylene fittings for use with outside diameter-controlled polyethylene pipe, covered by Specifications D 2447, D 2513, D 2737, D 3035, and F 714. Requirements for materials, workmanship, and testing performance are included. Where applicable in this specification "pipe" shall mean "pipe" or "tubing."

1.2 The values stated in inch-pound and centigrade temperature units are to be regarded as standard. The values given in parentheses are for information only.

The following safety hazards caveat pertains only to the test method portion, Section , 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.
