This Technical Report is applicable to the installation of thermoplastics piping systems to be used for the conveyance of water or sewage under gravity and pressure conditions underground. It is intended to be used for pipes of nominal size up to and including DN 1600.Wherever the term "pipe" is used in this Technical Report, it also serves to cover any "fittings", "ancillary" products and "components" if not otherwise specified.NOTE 1This document does not apply to pipelines for gas supply (see EN 12007-2, Gas supply systems pipelines for maximum operating pressure up to and including 16 bars - Part 2: Specific functional recommendations for PE- and MOP up to and including 10 bars).NOTE 2It is assumed that additional recommendations and/or requirements are detailed in the individual materials voluntary product standards. Instances where this is expected to apply include those indicated in this Technical Report as follows:a)any special transportation requirements (see 5.2);b)maximum storage height (see 5.2 and 5.4);c)maximum storage period in direct sunlight (see 5.4);d)any climatic conditions requiring special storage (see 5.4);e)limiting initial and/or long-term deflections (see 6.1.1 and 6.1.2);f)information on mole ploughing and boring (see and 6.2), if applicable;g)selection of appropriate jointing system (see Clause 7);h)recommended radii of curvature for cold bending (see 8.1);i)permitted rates of loss of water under test (see 9.2.1);j)if applicable the relationship between SDR and stiffness.Requirements and instructions concerning commissioning of systems can be found in EN 805 and EN 1610 and the relevant national and/or local regulations.
