This Technical Specification (CEN/TS) was approved by CEN on 24 March 2003 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. 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, Czech Republic, Denmark, Finland, France, Germany, Greece,
Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United
Kingdom.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this CEN Technical Specification: Austria, Belgium, Czech Republic, Denmark,

Introduction
[4] [5]
System Standards prEN 1796 and prEN 14364 specify the properties of a piping system and its components
when made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP)
intended to be used for pressure and non-pressure water or sewerage applications. A System Standard includes
specifications for pipes, fittings and joints and makes reference to supporting standards covering test methods,
recommended practices for installation (this Technical Specification) and procedures for assessment of conformity.
The committee is preparing a standard to cover matters such as design procedures, determination of long-term
safety factors based on a semi-probabilistic approach, surge allowance and allowable negative pressures fo
