Why offer a glossary?
In many texts or product decsriptions we like to work with abbreviations. These are common for our industry and most readers or customer know right away what is meant, because most of us use these in everyday worklife. For our English speaking customers we wanted to offer the opportunity to look up these abbrevations or terms that might not ring a bell right away. We hope this is helpful.

W 400 is a DVGW worksheet dealing with the planning of distribution systems for drinking water supply. The second part of the Worksheet W 400-2 “Construction and testing of water supply systems” states that water pipelines must be subjected to a leak test prior to commissioning. It is intended to check the quality of the entire pipeline construction and to ensure a reliable water supply and high drinking water quality. The current methods for leak testing water pipelines are pressure loss methods: the contraction method, the standard method and the accelerated standard method. W 400 is the German national standard for EN 805 which is also available as firmware. In addition to that we are able to implement individual and international company standards such as requested by companies like Gas Natural (Spain), Eandis (Belgium), EWE (Germany) and Avacon (Germany).
