Como-pex pipes meet and exceed the specifications set by the International ISO standards, the European Norms, the internationally accepted German DIN, the Spanish UNE, and the British BS standards. This results to that Como-pex pipes have not presented a single failure in the regular biannual tests carried out by the official institutes and bodies on random samples taken from the production and the warehouse. The outcome of the above is that Como-pex has been certified as a final product by the following organizations:
- EN ISO 9001:2008 by TÜV Germany for compliance with all international specifications pertaining to Como-pex.
- SKZ Germany, AENOR Spain, CSA Canada, GOST Russia, ZIK Croatia, for the physical and mechanical proper- ties of the pipe. The procedure concerns checking the dimensions of the pipe, determining the degree of cross- linking, microscopical material homogeneity assessment, hydrostatic pressure testing at various temperatures, melt flow rate testing and testing of the longitudinal heat reversion. - MPA-NRW Germany for oxygen permeability testing of Como-pex Oxygen Barrier pipes. It concerns a measurement that should comply with DIN 4726. - WRAS-NSF Great Britain for the suitability of Como-pex pipes for drinking water. It concerns tests carried out at 20°C and 80°C on taste, odor, development of microorganisms, extraction of substances and metals dangerous for public health (cadmium, arsenic etc.) Furthermore, the pipes are also controlled by ELOT (Greek Organization for Standardization-Laboratory of polymers) in hydrostatic pressure testing at 110°C and by the State General Chemical Laboratory for suitability for drinking water.
