Piping systems for rehabilitation of underground drainage, sewerage and water supply networks — Part 2: Thermoset composite materials prEN ISO 11300-2

Scope

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the rehabilitation of underground non-pressure and pressure drainage and sewerage networks, and of water supply networks which transport water intended for human consumption, including raw water intake pipelines.

It is applicable to the renovation technique family:
— lining with cured-in-place pipes (CIPP).

It applies to the use of thermoset composite materials with various thermosetting resin systems, in combination with compatible fibrous carrier materials, reinforcement, and other process-related plastics components (see 5.1).

It is applicable to pipes and fittings, as manufactured, as well as to the installed system, with service temperatures up to 50 °C for drainage and sewerage networks and up to 25°C for water supply networks.

For pressurised networks, this document applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure pipe liners, as defined in ISO 11295, which do not rely on adhesion to the existing pipeline.

It does not include requirements or test methods for resistance to abrasion, cyclic loading or impact, which are outside the scope of this document.
