This SAE Recommended Practice describes a unified numbering system (UNS) for metals and alloys which have a "commercial standing" (see 6.1), and covers the procedure by which such numbers are assigned. Section 2 describes the system of alphanumeric designations or "numbers" established for each family of metals and alloys. Section 3 outlines the organization established for administering the system. Section 4 describes the procedure for requesting number assignment to metals and alloys for which UNS numbers have not previously been assigned. The technical report covers technology, products, or processes which are mature and not likely to change in the foreseeable future.
