ISO, an acronym for International Standards Organization, is a standard of quality adapted by organizations worldwide. The acronym DIN stands for Deutsches Institut fur Normung, which, translated into English, is "The German Institute for Standardization." DIN and ISO standards are similar.
The ISO organization resulted from the convergence of two existing organizations: the International Federation of the Standardizing Associations (ISA) and the United Nations Standards Coordinating Committee (UNSCC). The purpose for ISO's creation was to establish an international standard of business practices, organization and production.
DIN was established in Berlin in 1917, and is still based there. It has been adopted as the national standard for Germany by the German Federal Government, and today 90 percent of the standards developed by DIN are international in scope. The economic benefits from standards for Germany alone is estimated at about 16 billion euros a year, as of 2009.
The DIN institute adopted a "DIN ISO" standard as an international norm for standards practices. The DIN ISO 7000 standard for use of uniform graphical symbols for use on equipment (such as symbols indicating safety, or the need to exercise caution) is one example of how the two standards bodies work in conjunction to adapt new international standards.
