Standard Specification for Aluminum Bars for Electrical Purposes (Bus Bars) (Metric) (Withdrawn 2024)
ABSTRACT
This specification covers Aluminum 1350 bar for electric conductors in the tempers. The tempers are designated as H12, H112, and H111. The products covered by this specification shall be produced by extruding or rolling. Bars in the H12 temper shall be furnished with a rolled mill finish; bars in the H111 temper, with an as-extruded mill finish; and bars in the H112 temper, with a rolled mill finish except that the edges shall be as sawed. The bars shall be subjected to tension test to determine their tensile and yield strengths. Bars in the H12, and H111, and H112 tempers shall be capable of being bent flatwise at room temperature, through an angle of 90° around a pin or mandrel having a radius equal to the thickness of the specimen, without cracking or evidence of slivers or other imperfections. For a flatwise bend, the pin or mandrel shall be 90° from the working (extrusion or rolling) direction, and across the greater (width) dimension of the bar. The required 90° bend shall be in the working (extrusion or rolling) direction. Bars in the H12 and H111 tempers whose width-to-thickness ratios are not in excess of 12 and whose width is 100 mm or less, shall be capable of being bent at room temperature edgewise 90° around a mandrel without cracking or localized thinning to less than 90 % of the maximum thickness within the central 60° of the bend when measured along the outer edge of the bend. Electrical resistivity and conductivity shall be measured.
SCOPE
1.1 This specification covers Aluminum 1350 bar for electric conductors in the tempers shown in Table 1. (A) For purposes of determining conformance with this specification, each value for tensile strength and yield strength shall be rounded to the nearest 1 MPa in accordance with the rounding-off method of Practice E29.(B) See Appendix X2.
1.2 Aluminum and temper designations are in accordance with ANSI H35.1M. The equivalent Unified Numbering System designation is A91350 in accordance with Practice E527.
Note 1: For Alloy 6101 bus conductors, refer to Specification B317/B317M.
Note 2: Prior to 1975, Aluminum 1350 was designated as EC aluminum.
1.3 This specification is the metric counterpart of Specification B236.
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A1.
WITHDRAWN RATIONALE
This specification covered Aluminum 1350 bar for electric conductors in the tempers shown in Table 1.
Formerly under the jurisdiction of Committee B07 on Light Metals and Alloys, this specification was withdrawn in December 2023 and replaced by Specification B236/B236M on Aluminum Bars for Electrical Purposes (Bus Bars).1
