Standards structure CEN/TC 155/WG 17 14 CEN/TC 155/WG 17 Renovation with plastics pipes Each of the System Standards comprises a: Part 1: General and all applicable renovation technique family related parts from the following list: Part 2: Lining with continuous pipes Part 3: Lining with close-fit pipes Part 4: Lining with cured-in-place pipes Part 5: Lining with discrete pipes Part 6: Lining with inserted hoses Part 7: Lining with spirally-wound pipes
CEN/TC 165 15 2004: Request for standardising an additional (non-plastics) technique family: 2004: CEN/TC 165 established WG 13 only for sewer applications Organisation: WG 13: convenor secretary Renovation and Repair of Drains and Sewers J.Brünecker H.J. Kropf, DIN 2010: EN 15885 Classification and characteristics of techniques for rehabilitation of drains and sewers incl. Repair techniques and Non-plastics materials 2013: Draft EN.

Meanwhile here in Denmark 16 1997: The Danish Quality Control Scheme for Pipeline Rehabilitation was founded Ensuring that contract work performed complies with: the quality manual of the company the declaration of the rehabilitation system in question The Control Scheme, currently only underground non-pressure drainage and sewerage networks, comprises: Renovation by lining with Cured-in-place pipes Renovation by lining with Close-fit pipes Replacement by Pipe bursting
ISO awake again 17 1989: ISO establish a working group for pipeline rehabilitation ISO / TC138 / WG12 Rehabilitation with plastics pipes and their constituents 1992: after publication of technical report ISO/TR 11295 working group put on hold because of parallel work going on in CEN (Europe) 2002: WG12 re-activated to bring the CEN standards to ISO level time to wake up! 2010: ISO 11295 Classification and information on design of plastics piping systems used for renovation.
ISO 11295: Definitions 18 rehabilitation all measures for restoring or upgrading the performance of an existing pipeline system renovation work incorporating all or part of the original fabric of the pipeline by means of which its current performance is improved replacement rehabilitation of an existing pipeline system by the installation of a new pipeline system, without incorporating the original fabric technique family group of renovation techniques which are considered to have common characteristics for standardisation purposes
