Elaboration of the DVGW standards takes place in the DVGW technical committees. It is incumbent upon the five steering committees (SC) to manage and control the technical work, to pass the standards as well as to co-organize the research work. The technical committees (TC) draw up the work schedules, coordinate the definition of rules, hold appeal negotiations,oversee the research projects and pass basic principles of certification. The formulation of rules, the preparation of technical statements, the formulation of basic principles of certification and vocational training are ultimately carried out in the project groups that are formed on a temporary basis depending on their task.
