Standard Test Methods for Fibrous-Insulated Magnet Wire

ABSTRACT
These test methods cover the testing of fibrous-insulated electrical conductors, commonly referred to as magnet wire, which are used in electrical apparatus. The test methods are intended primarily for evaluation of the electrical insulating materials used. It is intended that these test methods be used, except where modified by individual specifications for particular applications. This elongation testing method covers the determination of the elongation of fibrous insulated magnet wire that results in a fracture of the conductor. The electrical resistance testing method covers the determination of the electrical resistance of fibrous insulated magnet wire conductors. The fibrous coverage testing method covers the determination of the quality of fibrous servings on round magnet wire or bare conductor. The measurement of dimensions test methods determine the dimensions of the bare or film insulated conductor and the fibrous-insulated magnet wire. The adhesion and flexibility test method covers the evaluation of the flexibility and adherence of varnished fibrous glass, and varnished or unvarnished fibrous polyester-glass insulating material on either bare conductor, or film-insulated magnet wire. The dielectric breakdown voltage test method covers the determination of the dielectric breakdown voltage in air of insulation on round, rectangular, and square wires at commercial power frequencies.

Standard Specification for Aluminum Bars for Electrical Purposes (Bus Bars)

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.  
1.2 Aluminum and temper designations are in accordance with ANSI H35.1/H35.1(M). 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 The values stated in either SI or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.  
1.5 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.6 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.
