Concept in Definition ABC

DIN norms are the technical standards for the assurance of the quality in industrial and scientific products in Germany.

DIN standards represent regulations that operate on commerce, industry, science and institutions public regarding the development of German products. DIN is an acronym for 'Deutsches Institut für Normung', or 'German Institute for Standardization', which is the institution, based in Berlin and established in 1917, which deals with German standardization. The DIN performs the same functions as organisms internationals such as ISO.

DIN standards seek to correspond with the so-called "state of science", guaranteeing quality and safety on the production Y consumption. Sometimes the regulation of DIN standards influences the regulations of other international standardization bodies.

The DIN can be classified as "fundamental of general type" (standards of formats, types of lines, labeling and others), "fundamental technical" (standards of characteristics of mechanical elements and equipment), "materials" (quality standards of materials, designation, properties, composition, etc.), "of dimensions of parts and mechanisms" (standards of shapes, dimensions, tolerances). And they can also be classified according to their scope of application, such as "international", "regional", "national" or "company".

These rules are classified with various numbers and regulate all kinds of aspects of economic and productive life in Germany. For example, the rule DIN 476 defines the formats and sizes of papers that must be officially adopted.

The use of DIN standards can be seen, for example, in tool making. One case is the development of parts like a key, where the DIN regulates the voltages, tolerances and more specifications regarding the final product.

That a product complies with DIN standards is often and for the buyer and user of the same a guarantee of confidence, safety and quality.
