The work of preparing International Standards is normally carried out through 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 closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard 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 third edition cancels and replaces the second edition (ISO 3116:1981) which has been technically revised. Annexes A, B and C of this International Standard are for information only.

Some of the alloys referenced in this International Standard can be the subject of a patent or of patent applications and their listing herein is not to be construed in any way as the granting of a licence under such patent rights.

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

ISO 6892, Metallic materials Tensile testing at ambient temperature. EN 515, Aluminium and aluminium alloys Wrought products Temper designations. 3Designation 3.1Material The material shall be designated by symbols as given in Tables 1 to 11. The material symbol designations are in accordance with ISO 2092. NOTEA 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. 3.2Temper designation The following symbols shall be used for temper designation: ?O: annealed; ?F: as fabricated; ?H?8: fully hardened (strain hardened to give maximum ultimate tensite strength); ?H?4: half hardened (strain hardened to give an ultimate tensile strength approximately midway between that of annealed and H?8 temper); Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/19/2007 21:54:33 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 3116:2001(E) 2© ISO 2001 All rights reserved ?H?2: quarter hardened (strain hardened to give an ultimate tensile strength approximately midway between that of annealed and H?4 temper); ?T5: cooled from an elevated temperature shaping process and then artificially aged; ?T6: solution heat treated and then artificially aged. The temper designations are in accordance with EN 515. 3.3Designations 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. 3.4Designation for ordering EXAMPLE An order for magnesium 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 to be specified in addition. 4Requirements 4.1Chemical composition The chemical composition of wrought magnesium alloys shall conform to the requirements for the appropriate material given in Table 1. 4.2Mechanical properties The minimum values of the mechanical properties of wrought products in magnesium alloys in the defined temper conditions shall be as given in Tables 2 to 11. 4.3Frequency of testing The frequency of testing shall be subject to an agreement between the manufacturer and the purchaser. 5Sampling Conditions for sampling, formation of batches and frequency of verification shall be subject to an agreement between the manufacturer and the purchaser.
