DVGW (German Technical and Scientific Association for Gas and Water) is the largest gas and water industry certification body in Europe, covering all the certification procedures required in the gas and water sectors.

The main objective of all certification work is to ensure that there are no safety, hygiene or environmental objections to the products and companies certified. These activities are based on the DVGW standards as well as other national and international codes of practice, standards and certification programmes.

With a DVGW certificate, product manufacturers, specialist companies, utilities and experts can demonstrate to their customers and market partners that they comply with the state of the art in their field of activities.
