Foreword
This document (CEN/TR 1046:2013) has been prepared by Technical Committee CEN/TC 155 “Plastics
Piping Systems and Ducting Systems”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
This document supersedes ENV 1046:2001, ENV 1401-3:2001, CEN/TS 1852-3:2003 and
CEN/TS 14758-3:2006.
This Technical Report is based on the results of the work being 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) (see Bibliography), modified as necessary to be applicable to piping systems of any
thermoplastics materials and any relevant application.
Introduction
This Technical Report contains guidance for installation procedures for thermoplastics piping systems and
their components intended to be used below ground for pressure and non-pressure applications outside
building structures. It is intended to be used in conjunction with general standards for installation
recommendations, for example those issued by CEN/TC 164 “Water supply” and CEN/TC 165 “Waste water
engineering” as stated in EN 805 and EN 1610 respectively.
NOTE Guidelines for installation of pipelines made out of thermosetting materials can be found in the ISO 10465
series [11, 12, 13].
This Technical Report is based on the results from research with full-scale trials undertaken by the
thermoplastics pipes industry and expressed in CEN/TS 15223.
This Technical Report is a guidance document only. It provides a set of general guidelines which gives best
practices for installation of thermoplastics piping and ducting systems outside building structures underground.
This Technical Report includes recommendations for the pipe surround and backfilling procedures but not
road base and road sub-base details. Attention is drawn to any national regulations which may cover these or
other aspects of installation.
This Technical Report does not cover matters relating to renovation of existing pipeline systems using lining
techniques, or replacement of existing pipeline systems using trenchless techniques.
This Technical Report is intended to be used by authorities, design engineers, installation contractors and
manufacturers.
In this Technical Report, much of the guidance is expressed as requirements, e.g. by use of “shall” or by
instructions in the imperative. It is strongly recommended that these be followed whenever applicable.
Other guidance is presented for consideration as a matter of judgement in each case, e.g. by use of “should”.
