Abstract

Drinking water should be safe and pleasant to use, free of undesirable aesthetic aspects, such as objectionable odour or taste and contaminants that could lead to acute or chronic adverse health. Such contaminants can arise from the materials used to carry the drinking water to the consumer or store it during its distribution.

The Construction Products Directive (CPD) demands that such products satisfy 'Essential requirements' including requirements for safety and health. The quality of drinking water in EU countries is covered by the 'Drinking Water Directive' (DWD) but this does not cover many of the contaminants that can be associated with the products referred to above. Therefore most EU countries operate regulatory schemes for the approval and certification of such products and materials.

However, national schemes are different; an obstacle to trade that CEN is trying to remove. Harmonising the different schemes has met with difficulties. Mainly, that existing systems are heavily biased towards 'organic' products. The approval for metallic and cementitious products, is much more difficult because leaching from these products can be markedly influence by the chemical nature of drinking water. Development of a unified CEN system has proved difficult due to insufficient knowledge.

Test methods to examine the influence of materials in contact with water intended for human consumption are being developed by CEN/TC164/WG3 and its Ad Hoc groups. It has become apparent that a reliable test protocol for inorganic materials needs research information. The CEN/TC 164 committees to which WG3 reports, have reviewed the problem and recommended that co-normative research is carried out with some urgency.

The aim of the research was to provide background information to allow the appropriate CEN working groups to produce test methods for metallic and cement based materials.
