The German Institute for Standardization — Germany's national standards body and one of the world's most influential, with over 34,000 published standards. Many DIN standards have become the basis for corresponding ISO and EN (European) standards. DIN standards are particularly referenced in Latin America for: power transmission (DIN 7753 for V-belts, DIN 7721 for timing belts), bearings (DIN 625, DIN 635), fasteners (DIN 931, DIN 933 bolt standards), rubber testing (DIN 53505 Shore hardness, DIN 53516 abrasion), conveyor belts (DIN 22102 textile, DIN 22109 fire-resistant), and materials (DIN EN 10025 structural steel). The DIN numbering system is recognized worldwide, and many products in Mexico are specified by DIN designations even when equivalent ISO standards exist. DIN standards are developed by technical committees with industry participation and are published by Beuth Verlag. Access: most DIN standards are available for purchase from the Beuth web shop. In the rubber and power transmission industry, DIN 7753 (V-belt dimensions) and DIN 53505 (Shore hardness with 3-second reading) are among the most frequently referenced.
