This part of ISO 14531 provides guidance for the design, construction, installation and on-site testing of PE-X pipeline systems. The standard deals with trenchless and open-trench installation methods.
This part of ISO 14531, when used in conjunction with the other parts of ISO 14531, provides the basis for the design, manufacture and installation of PE-X piping systems (PE-X pipes, and PE-X and PE heat-fusion fittings and mechanical fittings) for the supply of category D and category E hydrocarbon-based fuels (see ISO 13623) at

This part of ISO 14531 provides for the jointing and installation of PE-X and PE heat-fusion fittings and mechanical fittings to PE-X pipes within the temperature range −5 °C to +40 °C. The jointing of pipes and fittings outside the stated temperature range should be the subject of consultation between the pipeline operator and the pipe, fitting and equipment manufacturers.
Users of this part of ISO 14531 should be aware that useful supplementary information is given in the standards listed in the bibliography.
