Plastics piping systems - Buried and above ground piping components for water and other liquids under pressure - Requirements and test/assessment methods for pipes and fittings
This European Standard specifies requirements for plastics pipes and fittings for pressure applications for water supply, drainage, sewerage and irrigation, as well as for any other pressure application in which other liquids are conveyed with the exception of water intended for human consumption.
It is intended to be used for buried or above-ground conveyance of water, raw water prior to treatment, waste water, water for general purposes, vacuum-operated soil and waste conveyance and other liquids under pressure, for both outside and inside buildings.
It gives the associated test/assessment methods.
This standard does not cover adhesives, joint sealings and gaskets.
NOTE 1 For this standard the term fitting includes the term joint as meant by mandate M 131.
NOTE 2 Products complying with this document may be used for the transport of water intended for human consumption if they comply with the relevant national, regional or local regulatory provisions applicable in the place of use. Compliance of a product with this document does not confer a presumption of fitness of the product for the transport of water intended for human consumption within the meaning of the Directive 89/106/EEC.
NOTE 3 In some countries products used for the transport of raw water have to comply with the same requirements as products used for the transport of water for human consumption.

Pipes and fittings for which the nominal pressure PN is declared in accordance with 4.3.1, and which have
been made of material meeting the requirements of 5.6.1, are deemed to have a reasonable economic
working life.
NOTE The piping components are expected to last at least the lifetime of the network where they are installed.
If the nature of the liquid is different from water or this liquid or water has a higher temperature than 20 °C
(35 °C for glass-reinforced thermosetting materials), guidance for de-rating the pressure shall be in
