Testing of products for use in contact with drinking water

To allow water quality requirements, as adopted by the particular authority responsible for water supply quality, to be met at consumers’ taps. Besides the effects of materials, this quality will depend on other factors, including commissioning and operational procedures such as flushing of mains, which are the responsibility of the local water agency.
