Most metric fasteners are made to the DIN standard-but what does DIN stand for?
Much the same way the American National Standards Institute (ANSI) was founded to promote U.S. voluntary standards and conformity for industry here in the U.S., the German counter-part, DIN, was established in 1917 in Berlin and has been adopted as the national standard by the German government. Originally founded as Normenausschuss der deutshen Industrie (NADI), the agency was formed to standardize German industrial practices and bring unity to the emerging German industrial machine. Its present name, Deutsches Institut Fur Normung (DIN), was adopted in 1975.
Originally founded by the Association of German Engineers, the German scientific community, and then adopted by the German government, the institute compiled and published industrial standards, unifying German manufacturing. At first specifically concerned with industrial practices, today DIN regulates everything from metric fasteners to alpine skiing and everything in between. As the American National Standards Institute (ANSI) was established to unify the American manufacturing industry, DIN was established in Germany to insure compatibility of parts and industrial practices throughout Germany and eventually the world market.
Germany has always excelled in its scientific, engineering, and manufacturing capabilities and their work in the development of the DIN standard has only improved their ability to compete in these highly technical fields. The DIN offices in Berlin were destroyed in air raids during World War II. It was not until 1946 that DIN was permitted to resume its work by the Allied Control Counsel. In 1951, DIN became a member of the International Organization for Standardization (ISO), ensuring a voice in the worldwide manufacturing community. The vast majority of metric fasteners are presently manufactured to the DIN standards, including Craftech’s line of plastic metric fasteners. DIN has been widely accepted as a metric standard worldwide and has improved the reputation of German technology and manufactured products around the world.
DIN is now in the process of revising its standards to match more closely the ISO standards. ISO standards are gaining popularity and will likely become the world standard. The American National Standards Institute (ANSI) metric standards are essentially in agreement with the ISO metric standards already.
DIN is a non-profit organization supported by its members’ membership fees. Din has nearly 1,700 members consisting of corporations, associations, public authorities, and other industry, commerce, trade, and research organizations. When creating or altering a standard, all members take an active role in the decision making process. DIN defines a standard as a document established by consensus and approved by a recognized body that provides, for common and repeated use, rules, guidelines, or characteristics for activities or results, aimed at the achievement of the optimum degree of order in a given context. Anyone can submit a new proposed standard for consideration. Once a proposal has been accepted, a standardization project is formed and involves all interested parties, who delegate experts to represent their interests in work groups overseen by DIN’s Standards Committee. DIN standards are based on a group consensus so work groups need to arrive at a common standpoint. Developing a standard involves extensive research on technological developments, economic impact, and international harmonization. Once discussion has reached a stage of initial agreement between all parties, the results are published as a draft and made available to the general public for comment. Comments received are reviewed and discussed in the work groups before the standard is finally published.
In our global economy, it is important that standards set by all organizations around the world find common ground. Since its founding in 1946, the International Standards Organization (ISO) has been working to justify the different standards. In a world of quickly evolving new technologies, the need for unity and conformity between all countries involved in the world supply chain grows ever more important. The DIN standard has given Germany a strong voice in the matter of world standards and will continue to do so for the foreseeable future.
