This Technical Specification (CEN/TS) was approved by CEN on 17 December 2005 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS available
promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the CEN/TS)
until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This Technical Specification (CEN/TS 14632:2006) has been prepared by Technical Committee CEN/TC155
"Plastics piping systems and ducting systems", the secretariat of which is held by NEN.
This Technical Specification can be used to support elaboration of national third party certification procedures for
GRP products (glass-reinforced thermosetting resins based on unsaturated polyesters) to be used in piping
systems for the transport of water, drainage and sewage.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United
Kingdom.
Introduction
This Technical Specification covers procedures and requirements for the assessment of conformity of materials,
components, joints and assemblies made from GRP (glass-reinforced thermosetting resins based on unsaturated
polyesters) intended to be used for drainage, sewerage or water supply. Requirements and test methods for
materials, pipes, fittings and joints are specified in the relevant system standards.

1 Scope
This Technical Specification gives guidance for parties involved in the assessment of conformity of piping systems
made from GRP-UP (glass-reinforced thermosetting resins based on unsaturated polyesters) intended to be used
for drainage, sewerage or water supply. It contains procedures for the assessment of conformity to the
requirements in the relevant system standards for materials, pipes, fittings and joints.
NOTE 1 These procedures can be included in the manufacturer’s quality plan as part of his quality system, which should
[1]
conform to EN ISO 9001 or other systems, as applicable.
NOTE 2 This Technical Specification can be included in a quality system subject to third party certification of conformity by a
[2] [3]
certification body that is accredited to EN 45011 or EN 45012 , as applicable.
