Enhancement of Microbial Growth 2012

The CE-mark will be mandatory for construction products in EU by 1.7.2013. However, the product acceptance scheme for products in contact with drinking water is still under preparation. Different materials, especially organic materials can support enhanced microbial growth in drinking water systems. The EN-standard test method for the influence of materials on water for human consumption — Enhancement of microbial growth has been under preparation in TC164/WG3/AHG3. The proposed standard has three different methodologies, ATP method, biomass volume method, and mean dissolved oxygen difference method.

The seminar was arranged in co-operation with TC164/WG3/AHG3, especially AHG3 convenor David Holt and it was kindly supported by the Ministry of the Environment, Finland. The seminar provided background information for different testing methods prior to the formal vote of the proposed standard.
