Plastics pipelines for the transport of gas, drinking water and waste water - Buttwelding of PE pipes and PE fittings

NEN 7200 gives specifications for the production and the assessment of buttwelded joints in pipes and fittings of polyethylene (PE 63, PE 80 and PE 100) as well as requirements for welding equipment and the traceability. This standard is applicable to welding equipment for the production of buttwelded joints and to buttwelded joints in pipes and fittings of polyethylene with a melt mass-flow rate between 0,3 g/10 min and 1,7 g/10 min in pipelines for natural gas.
