This is an incomplete list of DIN standards. The "STATUS" column gives the latest known status of the standard . If a standard has been withdrawn and no replacement specification is listed, either the specification was withdrawn without replacement or a replacement specification could not be identified.
The system is a catalogue of specifications in the English language, to allow buyers to purchase standardised materials all over the world. When MESC was initially introduced, materials were allocated a unique 7-digit number. This was increased to ten digits in 1946. [1] The system has a numerical "coding schedule" of 10 digits to code the ...

The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance). *The right-hand digit of the standard denotes 0 = normal chain, 1 ...
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
A common metal short-link chain Roller chains. A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension.

The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International.. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
