The suitability of materials for use in drinking water is regulated differently in each country. In general, the product must pass different chemical and microbiological tests by recognized test institutes.
In Germany, the "Guideline for hygienic assessment of organic materials in contact with drinking water" (KTW Guideline) of the Federal Environmental Agency and the”Arbeitsblatt” W270 of the DVGW (German Association for Gas and Water e.V.) must be observed. In the USA, the NSF International (National Sanitation Foundation) is responsible for testing and certification of materials and products for drinking water contact. In the UK, this task is performed by WRAS (Water Regulations Advisory Scheme). "Attestation de Conformité Sanitaire" (ACS) is the certificate that is required in France for materials and articles intended to come into contact with drinking water.
