Over deze norm
This part of ISO 11296, in conjunction with Part 1, specifies requirements and test methods for pipes which are formed on site by spirally winding and jointing a pre-manufactured profiled plastics strip, or a profiled plastics strip and integral locking joiner strip, and used for the renovation of underground non-pressure drainage and sewerage networks. It applies to spirally-wound pipes of fixed or variable diameter installed by one of two methods. The first method employs a dedicated winding machine in front of the open end of an existing pipeline, e.g. in a manhole. The pipes thus formed are simultaneously inserted into the existing pipeline by the winding forces, and by certain techniques can also be expanded in diameter after or during insertion. The second method employs a dedicated winding machine which forms the pipe as it traverses the existing pipeline from one manhole to the next. It covers spirally-wound pipes of fixed or variable diameter made of profiled plastics strips, with or without steel stiffening elements, of unplasticized poly(vinyl chloride) (PVC-U) with integral locking mechanism or high density polyethylene (HDPE) with integrally welded joints.
