【国外标准】 Standard Specification for Magnesium-Alloy Extruded Bars, Rods, Profiles, Tubes, and Wire

This specification covers magnesium-alloy extruded bars, rods, profiles, tubes, and wire. The bars, rods, profiles, tubes, or wire shall conform to the chemical requirements specified. Tensile properties such as tensile strength, yield strength, and elongation of magnesium alloys shall be determined. All material shall be of uniform quality, free from injurious surface defects, and shall have a workmanlike finish.1.1 This specification covers magnesium-alloy extruded bars, rods, profiles, tubes, and wire of the composition given in Table 1.1.2 The values stated in either inch-pound or SI units are to be regarded separately as standards. The SI units are shown in brackets or in separate tables or columns. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other. Combining values from the two systems may result in nonconformance with the specification.1.3 Unless the order specifies the “M” specification designation, the material shall be furnished to the inch-pound units.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
