PD CEN/TR 16950 contains the sanitary characteristics and test methods applicable to those factory-applied lining-, coating- and joining 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.
As ductile cast iron is impermeable against the diffusion of organic substances, the water quality is maintained in service. PD CEN/TR 16950 specifies different surface/volume ratios are used in the tests for pipes, fittings, and joints to reflect the different impacts of their surface areas exposed to the water in the overall pipeline.
PD CEN/TR 16950 on sanitary characteristics and test methods for ductile iron pipes is useful for:
Ductile iron pipes which are used for delivering water intended for human consumption need to satisfy certain sanitary requirements to ensure that they do not contaminate the water.
PD CEN/TR 16950 contains the essential sanitary characteristics to be verified in performance tests by materials of pipes, fittings, accessories of ductile cast iron and their joints, which are in contact with water intended for human consumption.
PD CEN/TR 16950 provides you with references to the documents that test the sanitary characteristics of the ductile iron pipes intended to come in contact with water meant for human consumption. PD CEN/TR 16950 also provides references to documents that will help you evaluate the test methods to determine the sanitation levels of the ductile iron pipes.
Overall, the guidelines of PD CEN/TR 16950 ensure that required levels of sanitation are maintained in the ductile iron pipes that are in contact with water inteded for human consumption.
