BS PD CEN/TR 16950:2016 contains the sanitary characteristics and test methods applicable to those factory applied lining-, coating- and jointing materials of ductile iron pipes and fittings conforming to EN 545 that are in contact with water intended for human consumption for use at operating temperatures up to 50 °C. Ductile cast iron itself is not in direct contact with the conveyed water and therefore no characteristics in respect to the sanitary behaviour are necessary. As ductile cast iron is impermeable against diffusion of organic substances, the water quality is maintained in service. Different surface/volume ratios are used in the tests for pipes, fittings and joints to reflect the different impact of their surface areas exposed to the water in the overall pipeline.
