KTW (plastics in drinking water, Kunststoff-Trinkwasser) is a German Federal Environment Office publication and defines hygiene requirements for plastics and silicones used in contact with drinking water (Kontakt mit Trinkwasser). The purpose of the KTW – W270 certification is to ensure that product elements in contact with drinking water have been tested and sanctioned by German laboratories (TZW and DVGW) in accordance with the guidance of the UBA (Umwelt Bundesamt). Manufacturers in Germany recognise KTW and W270 as the two main certifications regarding potable water.
