The work of preparing International Standards is normally carried out through
14、ISO technical committees. Each member body interested in a subject for which a technical committee has been established 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. ISO collaborates
15、 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval crit
16、eria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives). Attention is drawn to the possibility that some of the elements of this document may be the subjec
17、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www .iso .org/ patents). Any tra

It can also be applied for other purposes, such as heat treatment, forming and non-destructive testing. It covers grouping systems for the following standardized
23、materials: steels; aluminium and its alloys; copper and its alloys; nickel and its alloys; titanium and its alloys; zirconium and its alloys; cast irons. 2 Normative references There are no normative references in this document. 3 T erms an d definiti ons No terms and definitions are listed in this

25、 shown in Table 1. Only those elements that are specified in material standards or specifications should be considered. Ladle (or heat) analyses should be used in preference of product analysis when both are specified. The figures given in groups: 1, 2, 3 and 11 refer to the chemical composition spe
26、cified in the material standard (specified values); 4 to 10 are based on the elemental content used in the designation of the alloys. Materials assigned to a group in ISO/TR 20172, ISO/TR 20173 and ISO/TR 20174 should be considered assigned to those groups by this document. For materials that are no
27、t assigned to a group, the criteria of this document apply.
