The DVGW

Your network of excellence in the gas and water industry

The DVGW supports the gas and water industry in all technical and scientific areas. The main focus of the Association’s work is on safety and hygiene as well as environmental and consumer protection. The DVGW elaborates technical rules designed to promote the technical self-management of the German gas and water industry, thus ensuring the safe and secure supply of gas and water according to the highest international standards. The Association, which was founded in 1859, currently has approximately 14,000 members. The DVGW is free from economic and political influences.

Fuel analytics

Comprehensive characterisation of all types of fuels

In the fuel laboratory the focus is on characterising gaseous, liquid and solid fuels. In particular, we study the physical/chemical properties, composition, accompanying and trace substances as well as the generation of educts and intermediates. We offer our expertise as a service. This ranges from individual analyses, e.g. for quality assurance, through to permanent measurement campaigns as well as the set up and management of complex test apparatus. Our laboratory is an accredited test laboratory in line with DIN EN ISO 17025 for selected analysis methods and sampling techniques. (D-PL-12098-01-01). What’s more, we are constantly working to develop new and improve existing measurement methods and sampling techniques. We also carry out independent research projects and provide professional and practical support for various other such projects.
