Introduction
This European Standard specifies only those characteristics of pipes and fittings for pressure applications for
water supply, drainage, sewerage and irrigation with the exception of water intended for human consumption
that need to be known to determine if the works in which these are to be installed can satisfy the essential
requirements of the EU Directive(s). Additional characteristics are specified in the documents listed in clause 2
or in other appropriate product specifications.
This harmonised European Standard covers plastics pipes and fittings under pressure. Valves are covered by
CEN/TC 69.

1 Scope
This European Standard specifies product characteristics for plastics pipes and fittings for pressure
applications for water supply, drainage, sewerage and irrigation with the exception of water intended for
human consumption.
Pipes and fittings covered by this standard are intended to be used for buried or above-ground conveyance of
water, waste water, water for general purposes, vacuum-operated soil and waste conveyance, for both
outside and inside buildings.
It gives the associated test/assessment methods.
This standard does not cover valves, adhesives, joint sealings and gaskets.
NOTE Products complying with this document may be used for the transport of water intended for human
consumption and raw water prior to treatment 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 Regulation (EU)
No. 305/2011 (CPR).
