(Specification)Standard Specification for Electrofusion Type Polyamide-12 Fittings for Outside Diameter Controlled Polyamide-12 Pipe and Tubing for Gas Distribution
Standard Specification for Electrofusion Type Polyamide-12 Fittings for Outside Diameter Controlled Polyamide-12 Pipe and Tubing for Gas Distribution
ABSTRACT
This specification covers polyamide-12 electrofusion fittings for use with outside diameter-controlled polyamide-12 pipe and tubing for gas distribution. The materials are classified according to grade designations: Group 4, Class 2, and Grade 3. Minimum hydraulic burst pressure test, sustained pressure test, tensile strength test, joint integrity test, and voids evaluation shall be performed to conform to the specified requirements.
SCOPE
1.1 This specification covers polyamide- 12 electrofusion fittings for use with outside diameter-controlled polyamide- 12 pipe, covered by Specification F2785. Requirements for materials, workmanship, and testing performance are included. Where applicable in this specification “pipe” shall mean “pipe” or “tubing.”
1.2 Polyamide 12 electrofusion fittings are intended for use in polyamide 12 systems only. As per the manufacturer’s recommendations, no cross fusion between PA12, PA11 and PE is permitted.
1.3 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.
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 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.
