The value of 0. The material shall conform to the chemical composition requirements. In order to ensure uniformity in the test method and valid applicability of the test results to the conformance criteria, it is recommended that the rate of separation of the heads of ast, tensile test machine not exceed 0. 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.
The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Should any part of the fracture take place outside the elongation gage lines, or if examination of the tensile specimen indicates a?
Sampling, Testing, and Conformance Criteria The material shall conform to the chemical composition prescribed in Table 1. Tensile properties such as tensile strength b38 elongation and bending properties shall be determined via a tension test and bending test, respectively. 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.

A number in parentheses indicates the year of last reapproval. The sample sizes and conformance criteria are applicable only to lots produced by manufacturers that meet this requirement.
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.
Following welding, electric-butt welds shall be annealed for a distance of at least 6 in.

Combining values from the two systems may result in nonconformance with the specification. This abstract is a brief summary of the referenced standard. Elongation is the percent increase in length of the tensile specimen as b39 between gage marks originally spaced 10 in. 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.

This specification covers aluminum-alloy T81 round wire which are solution heat-treated, cold worked, and artificially aged for electrical purposes. Combining values from the two systems may result in nonconformance with the specification. The electrical resistivity and density of the wires shall be measured as well.
Corresponding values for other conductivities aluminum were derived from these by multiplying by the reciprocal of the conductivity ratios accurate to at least seven signi?

If the material is in coil form, one gaging shall be made near each end and one near the middle.
Tensile properties such as tensile strength and elongation and bending properties shall be determined via a tension test and bending test, respectively.
