CEN/TC 203/WG 7 develops CEN standards in the area of Information technology. The scope of work includes: To collect information and data in the field of materials in contact with potable water and to propose the relevant actions to the TC. Currently, there are 1 published standards from this working group.
The European Committee for Standardization (CEN) is a public standards organization that brings together the national standardization bodies of 34 European countries. CEN provides a platform for developing European Standards (ENs) and other technical documents in relation to various products, materials, services, and processes, supporting the European Single Market.
A Working Group in CEN is a specialized group responsible for developing standards or technical work within a defined scope. These bodies bring together international experts to create consensus-based standards that support global trade, safety, and interoperability.
This Technical Report 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 which 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 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.
