Drinking water needs to be healthy, clean and tasteless and its quality at the tap is determined by microbiological, chemical and organoleptic parameters. Currently in Europe, the compliance with the national drinking water regulations is required and the absence of a harmonized European regulation generates intense debates in the marketplace regarding the best suited materials for drinking water pipes. The inherent microstructure of DOWLEXTM PE-RT materials ensures the temperature resistance required by the hot & cold water pipe applications without the need of chemical post-modification of the material. The absence of added chemical compounds which can migrate to water ensures a low level of taste and odour of the water exposed to the pipes, complying with current regulations. Taste and odour investigations are conducted internally and externally to ensure the inertness of our materials to the water organoleptics. The combined efforts of a large trained human sensory panel and our electronic capabilities allow us to ensure fast, statistically significant and reproducible results.
