Abstract

Ïã¸ÛÁùºÏ²Ê¿ª½± 11297-4:2018, in conjunction with Ïã¸ÛÁùºÏ²Ê¿ª½± 11297‑1 and Ïã¸ÛÁùºÏ²Ê¿ª½± 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.

Ïã¸ÛÁùºÏ²Ê¿ª½± 11297-4:2018 applies to independent (fully structural, class A) and interactive (semi structural, class B) pressure pipe liners, as defined in Ïã¸ÛÁùºÏ²Ê¿ª½± 11295, which do not rely on adhesion to the existing pipeline.

Ïã¸ÛÁùºÏ²Ê¿ª½± 11297-4:2018 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).

Ïã¸ÛÁùºÏ²Ê¿ª½± 11297-4:2018 does not include requirements or test methods for resistance to abrasion, cyclic loading or impact, which are outside the scope of this document.
