BS EN ISO 11297-4:2018, in conjunction with ISO 11297-1 and ISO 11296-4, specifies requirements and test methods for cured-in-place pipes and fittings used for the renovation of hydraulically and pneumatically pressurized underground drainage and sewerage networks with service temperatures up to 50 °C.

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

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