Deutsche Vereinigung des Gas- und Wasserfaches
The German Association of Gas and Water Industry Association eV - Technical and Scientific Association is the industry association of the German Gas and Water Management, based in Bonn. The association is involved in self-government with technical and scientific tasks of the fuel gas and water supply.
The DVGW was founded in 1859 in Frankfurt aM and currently has 13,541 members, including 1,903 utilities, 1,386 companies, 252 agencies, institutions, organizations, and 10,000 individual members (as of 1 October 2013 ).
By the end of 1995, the DVGW was incumbent on the national test and marking of gas appliances in Germany.
The association in the legal form of a registered association is independent and recognized as charitable. Its main task is the preparation of the Technical Regulations, with the safety and reliability of the gas and water supply is guaranteed.
The experts of the interested parties create in voluntary cooperation, the DVGW regulations. This means that the technical rules can be developed for the gas and water industry by the industry itself (technical autonomy ). This can result in recognized rules of technology ( AART ), is often referred to in the legislative reference. Compliance with these rules is not a constraint. However, they are standard in case of damage and you can get quasi " legislative acts " in relation to tort law, provided that the underlying law so provides. For example, then it must be shown in case of damage, that at least the Aart were met.
