ContiTech Industrial Hoses The best for drinking water Water intended for human consumption is subject to the stringent provisions of the drinking water regulations (Trinkwasserverordnung), which also encompass the transport of drinking water. This results in very specific requirements – both hygienic and mechanical – for hoses and hose lines. This document describes the exact regulations and test specifications for hoses intended for the transport of drinking water. A person can survive three months without food, but just three days without water, making it the most important of our basic forms...

Drinking water regulations (Trinkwasserverordnung) With the drinking water regulations (TrinkwV 2001), the legislator has translated the provisions of the European Drinking Water Directive (98/83/EG) into national law. The purpose of the drinking water regulations is to protect human health against detrimental effects that may result from the potential contamination of water. According to the regulations, drinking water must be esculent and pure. The drinking water regulations also stipulate which materials may be used in contact with drinking water. According to Section 17, materials must not...

DVGW W270 During tests in accordance with DVGW W270, hoses are examined for microbial safety. The test examines whether the number of microorganisms on the inner surface of the hose increases when the material has longer periods of contact with drinking water. For this purpose, water is passed through the hose for several months and any potential microbial growth (biofilm) is subsequently scraped off. The amount of biofilm must not exceed a certain limit. Plasticisers in particular can stimulate the formation of biofilm and should therefore be used only sparingly or not at all. Tests in accordance...

Not every hose is a drinking water hose Only drinking water hoses tested by accredited test centres on behalf of the DVGW are approved for the transport of drinking water. DIN 2001-1+2 Technical standard DIN 2001-1+2 covers the supply of drinking water from small units and non-stationary units, which affects trade fairs, markets, and festivals, etc. The drinking water supply systems must be planned, installed, and operated in such a way that even if several foreseeable, extreme operating conditions occur (e.g. heating of the storage tanks/hoses in the summer, vibrations), drinking that meets...
