    Abstract - (Show below) - (Hide below)

    This European Standard describes the specific functional requirements for polyethylene (PE) pipelines in addition to the general functional requirements of EN 12007-1 for: a) a maximum operating pressure (MOP) up to and including 10 bar; b) an operating temperature between -20 °C and +40 °C This European Standard covers three types of pipe: - PE pipes including any identification stripes; - PE pipes which co-extruded layers on either or both the outside and/or inside of the pipe; - PE pipes with a peelable, contiguous thermoplastic additional layer on the outside of the pipe
