1.1 This specification covers 8000 series aluminum alloys fabricated into round wires in annealed or intermediate tempers suitable for stranding into conductors or for solid single conductors, usually to be insulated.
1.2 The SI values for resistivity are regarded as standard. For all other properties, the inch-pound units are regarded as standard and the SI units may be approximate. N OTE 1—Aluminum alloys capable of meeting the requirements of this specification are listed in Table 1. N OTE 2—The alloy and temper designations conform to ANSI H35.1. Unified Numbering System alloy designations are listed in Table 1 in accordance with Practice E527. N OTE 3—Certain aluminum alloys may be subject to patent rights. U.S. patents numbers are shown in Table 1.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use.
1.4 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4.1 The wire shall be made from drawing stock meeting the chemical composition limits for alloys shown in Table 2 that are presently registered with registration record or for such other alloys which may become available and will meet the requirements of this specification.
4.1.1 This specification applies to alloys that are recognized by Underwriters Laboratories, such as aluminum conductor material.
4.2 Unless otherwise specified, the manufacturer shall have the option of producing the intermediate temper by either strain-hardening only (H1X) or by strain-hardening and partial annealing (H2X) before or after stranding. (Explanatory Note 1 and ANSI H35.1.)
9.1 The diameter of the wire shall be specified in inches to the nearest 0.0001 in.; or it shall be specified in millimetres to the nearest 0.001 mm for wires less than 1.000 mm in diameter, and to the nearest 0.01 mm for wires 1.00 mm in diameter or larger. The actual wire diameter shall not vary from the specified diameter by more than the values shown in Table 5.
9.2 Standard nominal diameters of wire used for solid conductors are shown in Table 6. Diameters of wires used for stranded conductor shall be as agreed upon between the purchaser and the manufacturer.
NOTE 1—The H1X tempers (strain-hardened only) and the H2X tempers (strain-hardened followed by partial annealing) are considered equally suitable for most electrical purposes. N OTE 2—In tension tests, the values obtained may be affected by testing speed. It is recommended that for conformance criteria the testing speed should not exceed 0.5 mm/mm of gage length or distance between grips per minute. N OTE 3—Relationships that may be useful in connection with the values of electrical resistivity prescribed in this specification are shown in Table X1.1. Resistivity units are based on the International Annealed Copper Standard (IACS) adopted by IEC in 1983, which is 1/58 Ω mm 2 /m at 20°C for 100 % conductivity. The value of 0.017241 Ω mm 2 /m at 20°C is the international equivalent of volume resistivity of annealed copper for 100 % conductivity. A complete discussion of this subject is contained in NBS Handbook 100. The use of five significant figures in expressing resistivity does not imply the need for greater accuracy of measurement than that specified in Test Method B193. The use offive significant figures is required for reasonably accurate reversible conversion from one set of resistivity units to another. The equivalent resistivity values in the tables were derived from the fundamental IEC value (1/58 Ω mm 2 /m) computed to seven significant figures and then rounded to five significant figures.
