Price based on 1 page Foreword ISo (the International Organization for Standardization) is a worldwide federation of national standards institutes (IsO member bodies). The work of developing Inter- national Standards js carried out through Iso technical committees. Every member body interested in a subject for which a technical committee has been set up has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with Iso, also take part in the work. the member bodies for approval before their acceptance as International Standards by the ISo Council. Standard IS0 1190/1 was developed by Technica! Committee International ISO/TC 26, Copper and copper alloys, and was circulated to the member bodies in August 1981.

The alloying elements shall be This part of iso 1190 relates to the designation of coppers and listed in decreasing order of percentages (for example copper alloys in terms of their material composition. CuZn36Pb3) or, if of equal percentage, in alphabetical order of the chemical symbols (for example CuA/10Fe5Ni5), provided that the principal alloying element of the type of alloy is listed first irrespective of its content (for example CuNi18Zn27 - not Material designation 2 CuZn27Ni18). Due to similar composition limits, wrought and cast alloys may 2.1 Basis of designation have the same designation. Therefore, in any case, cast alloys shall have the prefix G - for identification. The material designations of copper and its alloys shall 2.1.1 be based on the chemical composition limits. According to the casting process, the following prefixes apply : NOTE - Alternative numerical designation systems for metals are cur- rently under discussion. GS : sand casting GM : permanent mould casting 2.1.2 All material designations shall have the prefix "Iso". GZ : centrifugal casting NOTE -- This prefix may be omitted for brevity in International Stan- dards as well as in correspondence where it is obvious that IsO GC : continuous casting designations are used. GP : pressure die casting 2.1.3 International chemical symbols shall be used for the designation of the base element and the major alloying NOTES numbers indicating the nominal alloy content. 1 The designation of a casting alloy in ingot form is derived from the composition specified for the corresponding alloy in the form of castings. This is to avoid confusion in instances where a narrower com- 2.1.4 Assignment or revisions of material designations shal position range for ingot metal would give a different mean alloy con- be app
