1.1 This specification covers polyethylene (PE) pipe made in three standard outside diameter sizing systems, based on outside diameters of DIPS 3, IPS 4, Metric 90 mm and larger. For smaller sizes refer to Specification D3035 . See 5.2.5 for guidelines on special sizes. 1.2 The piping is intended for new construction and insertion renewal of old piping systems used for the transport of water, municipal sewage, domestic sewage, industrial process liquids, effluents, slurries, etc., in both pressure and nonpressure systems. Note 1: The user should consult the manufacturer to ensure that any mechanical or chemical effects to the polyethylene pipe caused by the material being transported will not affect the service life beyond limits acceptable to the user. See PPI TR-19 Chemical Resistance of Thermoplastic Piping Materials for guidance on chemical effects, www.plasticpipe.org 1.3 All pipes produced under this specification are pressure-rated. See Appendix X5 for information on pressure rating. Note 2: References and material descriptions for PE2406, PE3408 and materials having a HDB of 1450 psi have been removed from Specification F714 due to changes in Specification D3350 and PPI TR-3. For removed designations, refer to previous editions of Specification F714 , Specification D3350 , PPI TR-3 and PPI TR-4. The removal of these materials does not affect pipelines that are in service. See Note 4 and Note 9 . 1.4 This specification includes criteria for choice of raw material, together with performance requirements and test methods for determining conformance with the requirements. 1.5 Quality-control measures are to be taken by manufacturers. See Appendix X4 for general information on quality control. 1.6 Units— 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. 1.7 The following safety hazards caveat pertains only to the test methods portion, Section 6 , 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. 1.8 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.
