BSI Group, also known in its home market as the British Standards Institution (or BSI), is a multinational business services provider whose principal activity is the production of standards and the supply of standards-related services. BSI produces British Standards, and, as the UK’s National Standards Body, is also responsible for the UK publication, in English, of international and European standards. The Group now operates internationally in 150 countries.


50x50

The UNS for Metals and Alloys provides a means of correlating many internationally used metal and alloy numbering systems administered by societies, trade associations, and individual users and producers of metals and alloys. Jointly developed by ASTM International and the Society of Automotive Engineers (SAE), it provides the uniformity necessary for efficient indexing, record keeping, data storage and retrieval, and cross-referencing.
