B39 electrical resistivity and density of the wires shall be measured as well. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
Sustainable Development Goals and standardisation, how do they connect? This abstract is a brief summary of the referenced standard.
ASTM B∕BM 电气用铝合金T81线_百度文库
Should any part of the fracture take place outside the elongation gage lines, or if examination of the tensile specimen indicates a? Elongation is the percent increase in length of the tensile specimen as measured between gage marks originally spaced 10 in.
NOTE 3—The speed of testing can affect the results of the tensile strength and elongation test. No fracture shall occur. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
If the material is in coil form, one gaging shall be made near each end and one near the middle. Slight surface checks shall not consititute cause for rejection.
The electrical resistivity and density of the wires shall be measured as well.
Following welding, electric-butt welds shall be annealed for a distance of at least 6 in. Such tests shall show the tensile strength to be not less than 42 ksi MPa for cold-pressure welds and for electric-butt, cold-upset welds and not less than 15 ksi MPa for electric-butt welds. Material and Manufacture 5. What is a standard? Workmanship, Finish and Appearance Aluminum-alloy corresponds to unified numbering system alloy A in accordance with Practice E Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.

The values bb398 each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. Inspection of lots of less than lb [ kg] of wire cannot be justi?

If, however, the presence of other elements is suspected or indicated in amounts greater than the speci? Obtain the tensile strength, using Test Methods Bby dividing the maximum load resisted by the tensile specimen, with the tensile stress to be expressed in kips lbf. Valid Buy this standard. Test shall be run on the six additional specimens, and a numerical average of the ten tested specimens shall be calculated and considered the lot average.
