Electrofusion fittings may feature exposed metallic components. 5.2 Colour The pipes and fittings shall be coloured through the wall. The colour should preferably be black or as agreed between manufacturer and purchaser. A deviating colour for a co-extruded inner layer is permitted provided the material of this layer conforms to Clause 4. 6 Geometrical characteristics 6.1 General Dimensions shall be measured according to EN ISO 3126.
