1. Scope 1.1 This specification covers metric outside diameter polyethylene (PE) pipe made from polyethylene compound that qualifies for MRS, HDB and HDS ratings and for PE100 and PE4710 designations. Included are requirements for polyethylene compound, workmanship, dimensions, short-term stress and ductility, long-term stress, marking, quality assurance and verification of joining. 1.1.1 Polyethylene pipe in accordance with this specification is intended to be 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 non-pressure conveyance of liquid or gaseous media. Pipes produced under this specification are not intended as enclosures for electrical or communications components. NOTE 1The user should consult the manufacturer to determine if the media being conveyed is compatible with polyethylene pipe and will not affect service life beyond limits acceptable to the user. The media being conveyed may be subject to statutory codes or regulations that can affect conditions of conveyance. NOTE 2Long and short-term mechanical properties related to axial and hoop tension, compression, creep, strain, bending, fatigue, shear and the like will vary with temperature, and with the 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. The maximum recommended service temperature for sustained internal pressure service is 60C. The maximum recommended sustained service temperature for non-pressure service is 82C. 1.3 The values stated in SI units are to be regarded as 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.
