DIN РGerman Standards 

DIN, the German Institute for Standardization, offers stakeholders a platform for the development of standards as a service to industry, the state and society as a whole. A registered non-profit association, DIN has been based in Berlin since 1917.
DIN’s primary task is to work closely with its stakeholders to develop consensus-based standards that meet market requirements. Some 26,000 experts contribute their skills and experience to the standardization process.By agreement with the German Federal Government, DIN is the acknowledged national standards body that represents German interests in European and international standards organizations. Ninety percent of the standards work now carried out by DIN is international in nature.
