Liner Testing in Europe - Methods, Standardization, and Experience

The article is essentially dealing with new a system of quality control applied in an increasing number on German relining job sites. The system was worked out since 2004/2005 by a round table group of recognized experts initiated and organized by eight southern German cities. This group agreed on the most proven and scientifically sound, most reliable and most evident testing methods based on existing DIN EN ISO standards. The results are compiled in the two brochures DWA 143-3 and DWA 144-3 (DWA: German association of water industry, wastewater and waste). "Additional Technical Terms of Contract" were introduced in order to make the new system and its rules legally binding for CIPP jobs. The new system covers a number of quality related measures on the job site including sample preparation and it defines a two-step lab investigation of the sample. If the sample passes step 1 the liners' material properties are accepted. If the sample does not pass it is investigated more in detail in step 2 to make clear what the problems are and how to overcome them. Additionally, the new system is providing a standard static liner design that makes individual static calculations for usual relining job sites (significantly damaged but stable sewer, no peculiarities) superfluous.
