Standard Specification for Polyethylene (PE) Thermoplastic High-Pressure Irrigation Pipeline Systems (Withdrawn 2014)

ABSTRACT
This specification covers classification criteria, nomenclature system, requirements, test methods, joints, fittings, certification, and marking for polyethylene (PE) thermoplastic high-pressure irrigation pipeline systems. PE materials for pipe are categorized by short-term and long-term strength tests. Materials shall meet the requirements of basic PE grades. Test methods for pipe shall include dimensions, tolerances, sustained pressure, burst pressure, carbon black content, density, and elevated temperature test. Joints and couplings shall withstand the design maximum working pressures. Plastic fittings shall meet all the dimensional and quality requirements.
SCOPE
1.1 This specification covers polyethylene (PE) thermoplastic pipelines used to convey, at rated pressures of 80 to 200 psi, water that is to be used for irrigation purposes. This specification includes criteria for classifying the pipe materials, a system of nomenclature for plastic pipe, requirements for pipe, test methods, joints, fittings, certification, and marking.
1.2 The values stated in inch-pound units are to be regarded as the standard.
1.3 The following safety hazards caveat pertains only to the test method portion, Section 7, 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.
WITHDRAWN RATIONALE
This specification covers polyethylene (PE) thermoplastic pipelines used to convey, at rated pressures of 80 to 200 psi, water that is to be used for irrigation purposes. This specification includes criteria for classifying the pipe materials, a system of nomenclature for plastic pipe, requirements for pipe, test methods, joints, fittings, certification, and marking.
Formerly under the jurisdiction of Committee F17 on Plastic Piping Systems, this specification was withdrawn in December 2013. This standard is being withdrawn without replacement due to its limited use by industry.
