(21) The nature of materials that come into contact with water intended for human consumption can have an impact on the quality of such water through the migration of potentially harmful substances, by enhancing microbial growth or by influencing the odour, colour or taste of such water. The evaluation of Directive 98/83/EC found that the provisions on quality assurance of treatment, equipment and materials provided too much legal flexibility, leading to different national approval systems across the Union for materials that come into contact with water intended for human consumption. Therefore, there is a need to establish more specific minimum hygiene requirements for materials intended to be used for the abstraction, treatment, storage or distribution of water intended for human consumption in new installations or in existing installations in the case of repair works or reconstruction, in order to ensure that they do not compromise human health either directly or indirectly, adversely affect the colour, odour or taste of the water, enhance microbial growth in the water or cause contaminants to leach into the water at levels that are higher than necessary in view of the intended purpose. For this purpose, this Directive should set out specific minimum hygiene requirements for materials, by establishing methodologies for testing and accepting starting substances, compositions and constituents, European positive lists of starting substances, compositions and constituents, methods and procedures for inclusion of starting substances, compositions or constituents in the European positive lists or reviewing their inclusion, and procedures and methods for testing and accepting final materials as used in a product made from combinations of starting substances, compositions or constituents on the European positive lists. In order not to hamper innovation, the Commission should ensure that such procedures are proportionate, and that they do not place an undue burden on economic operators, in particular small and medium-sized enterprises. To the extent possible, such procedures should be aligned with the existing Union product legislation, in order to avoid a double burden obliging economic operators to carry out different conformity assessments for the same product.
