Nordic Poly Mark
Nordic quality mark for plastic pipe products.
Nordic Poly Mark is a Nordic quality mark for plastic pipe products. This quality stamp has been developed jointly by the Nordic countries in order to maintain a high level of quality plastic pipe products for the Nordic market. Extena’s PE100 RC pipes meet all the requirements for Nordic Poly Mark by a very good margin. However, we believe that the present requirements of Nordic Poly Mark are too low with regards to RC material and slow crack growth (SCG).
