11、word ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a techn
12、ical 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 closely with the International Electrotechnical Commission (IEC) on all matters of
13、electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to
14、 the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for
15、identifying any or all such patent rights. ISO 3116 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee SC 5, Magnesium and alloys of cast or wrought magnesium. This fourth edition cancels and replaces the third edition (ISO 3116:2001), which has been technical
16、ly revised. The reason for this fourth edition is to clarify that requirements for chemical composition relate to cast analysis, and to adjust elongation values for some alloys and tempers.

24、be designated by symbols as given in Tables 1 to 11. The material symbol designations are in accordance with ISO 2092. NOTE A list of national designations corresponding to this International Standard is given in Annex A and a table of physical properties of the listed alloys is given in Annex B. 3.
25、2 Temper designation The following symbols shall be used for temper designation: O: annealed; F: as fabricated; H8: fully hardened (strain hardened to give maximum ultimate tensite strength); H4: half hardened (strain hardened to give an ultimate tensile strength approximately midway between that of
26、 annealed and H8 temper); Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 05/08/2007 08:05:26 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 3116:2007(E

28、y aged. The temper designations are in accordance with EN 515. 3.3 Designations of product form The following symbols shall be used for product form: B: bars and solid sections; T: tubes and hollow sections; F: forgings; P: plate and sheet. 3.4 Designation for ordering EXAMPLE An order for magnesium
29、 bars, conforming to this International Standard, of magnesium alloy ISO-WD 21150, delivered in the as-fabricated condition (F) is as follows: ISO 3116 - ISO-MgAl3Zn1 (A) (or WD21150) - F - B Tonnage and dimensions are to be specified in addition. 4 Requirements 4.1 Chemical composition The chemical
30、 composition of wrought magnesium alloys, taken as cast analysis at the time the material is cast, shall conform to the requirements for the appropriate material given in Table 1. 4.2 Mechanical properties The minimum values of the mechanical properties of wrought products in magnesium alloys in the
31、 defined temper conditions shall be as given in Tables 2 to 11. 4.3 Frequency of testing The frequency of testing shall be subject to an agreement between the manufacturer and the purchaser. 5 Sampling Conditions for sampling, formation of batches and frequency of verification shall be subject to an
32、 agreement between the manufacturer and the purchaser.
