This document specifies the characteristics of pipes (mains, sub-mains and laterals) made from polyethylene (PE), intended for the conveyance of water for irrigation, at a water temperature up to 45 °C. NOTE 1 For the effect of water temperature on the maximum operating pressure, see Annex A. This document applies to pipes that will not be subjected to internal pressure for long periods, and not more than 1 500 hours/year. For piping applications with long-term continuous pressure, the ISO 4427 series applies. NOTE 2 The expected lifetime of pipes covered by this document is ten years or less. This document also specifies the properties of the material and the parameters for the test methods to which it refers.

The recommendations are intended to give practical guidance of design and installation of piping systems incorporating pipes, fittings, valves, and ancillary equipment made from PVC materials and used for the following purposes: water mains and services buried in ground, waste water under pressure, and conveyance of water above ground for both outside and inside buildings, for the supply of water under pressure at approximately 20 °C (cold water) intended for human consumption and for general purposes. ISO/TR 4191:2014 is also applicable to components for the conveyance of water up to and including 45 °C. For temperatures between 25 °C and 45 °C, Figure 1 of ISO 1452‑2:2009 applies.

In conjunction with the other parts of ISO 15874, it is applicable to PP pipes, fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for hot and cold water installations.

ISO 15874-2:2013 specifies the requirements of pipes made from polypropylene (PP) for piping systems intended to be used for hot and cold water installations within buildings for the conveyance of water whether or not intended for human consumption (domestic systems) and for heating systems under operating pressures and temperatures appropriate to the class of application. It covers a range of service conditions (application classes), design pressures and pipe dimension classes. It also specifies test parameters for test methods. In conjunction with the other parts of ISO 15874, ISO 15874-2:2013 is applicable to PP pipes, their joints and to joints with components of PP, other plastics and non-plastics materials intended to be used for hot and cold water installations. It is applicable to pipes with or without (a) barrier layer(s).

ISO/TR 27165:2012 provides definitions for wall constructions of thermoplastics pipes intended to be used in pressure and non-pressure pipe applications. It takes into account as far as possible already existing definitions in published product standards and gives guidance for a common text when drafting new deliverables or revising existing ones.
