    1. Scope

    1.1 This specification covers metric outside diameter polyethylene (PE) pipe made from minimum required strength (MRS) and HDB-and HDS-rated PE compounds that meet requirements as PE100 and PE4710 and provide for pipes that are pressure rated for water (PN). Included are requirements for polyethylene compounds, workmanship, dimensions, sustained pressure, burst pressure, marking, and verification of joining. 1.1.1 PE pipe in accordance with this specification is intended to be dimensionally compatible with nominal diameters and nominal pressures in accordance with ISO 161-1 and wall thickness in accordance with ISO 4065. 1.2 Pipes produced under this specification are intended for the pressure or nonpressure transport of liquid media such as municipal and private potable and nonpotable water, industrial and mining process liquids, effluents, slurries, sewage, storm drainage, and pressure or nonpressure transport of gaseous such as odor control, or compressed air or other gases. Excluded uses are the distribution of natural and other fuel gas that is restricted by governmental regulation and use for electrical or communication duct (conduit). NOTE 1-The user should consult the manufacturer to determine if the intended use (application) and the fluid media being transported are compatible with PE pipe and will not affect the service life beyond limits acceptable to the user. NOTE 2-Internal pressure service at temperatures above 20C, the transport of fluid media other than water, and application conditions (installation and operation) will affect (usually reduce) maximum allowable operating pressure (PFA). The maximum recommended service temperature for sustained internal pressure service is 60C. NOTE 3-The maximum recommended sustained service temperature for nonpressure service is 82C. NOTE 4-Long- and short-term mechanical properties related to tension, compression, creep, strain, bending, fatigue, shear, and the like will vary with temperature and magnitude and duration of applied stress. Designers should take variation of mechanical properties into account using information from manufacturers and industry technical resources such as the Plastics Pipe Institute. 1.3 The values stated in SI units are to be regarded as the standard. 1.4 The following safety hazards caveat pertains only to the test methods 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.

    Project 26-12-19--This specification provides criteria for MRS-rated PE compounds for metric dimension PE pressure piping that is dimensionally compatible with internationally available metric-sized PE piping systems for municipal, industrial, mining, and other pressure and nonpressure fluid applications.
