Systems Part 4.Cured-in-place lining method
1 Scope
This document specifies the following procedures for trenchless repair of underground non-pressure drainage networks with working temperatures not exceeding 50°C using the in-situ cured lining method.
The requirements for plastic piping systems used in the production phase ("M" phase) of lined hoses and the construction phase ("I" phase) after curing of the lined pipes are described.
The corresponding test methods specify the contents of construction and acceptance.
This document applies to all thermosetting resin systems, carrier materials, reinforcement materials, process-related plastics and other materials used in the cured-in-place lining process.
Material film and installed cured liner pipe system.
