System Standards are based on the results of the work undertaken in ISO/TC 138 "Plastics pipes, fittings and
valves for the transport of fluids", which is a Technical Committee of the International Organization for
Standardization (ISO).
They are supported by separate standards on test methods to which references are made throughout the System
Standard.
The System Standards are consistent with general standards on functional requirements and on recommended
practice for installation.
EN 1456 consists of the following Parts, under the general title Plastics piping systems for buried and above-
ground drainage and sewerage under pressure — Unplasticized poly(vinyl chloride) (PVC-U)

Introduction
The System Standard, of which this is Part 2, specifies the requirements for a piping system and its components
when made from unplasticized poly(vinyl chloride) (PVC-U). The piping system is intended to be used for buried
and above-ground drainage and sewerage under pressure.
For material, piping components and their fitness for purpose requirements and test methods are specified in
EN 1456-1.
This Part of EN 1456 gives guidance for the assessment of conformity of products covered by EN 1456-1. It can be
used integrally and/or be used for inclusion of conformity assessment in the manufacturer's quality plan as part of
the quality system for attestation purposes. The use of this Technical Specification does not necessarily imply the
involvement of a third party.
It can also be used to support the elaboration of national third party certification procedures for products
conforming to EN 1456-1. It is the responsibility of the manufacturer to choose or not to choose for the involvement
of a third party for certification purposes.
