Standard Specification for Aluminum-Alloy 6201-T81 and 6201-T83 Wire for Electrical Purposes

Inspection of lots of less than lb [ kg] of wire cannot be justi? The electrical resistivity and density of the wires shall be measured as well. If additional information is to be required on the tags, it shall be arranged with the manufacturer at the time of purchase.

This abstract is a brief summary of the referenced standard. Elongation is the percent increase in length of the tensile specimen as measured between gage marks originally spaced 10 atm. Your shopping cart is empty. In order to ensure uniformity in the test method and valid applicability of the g398 results to the conformance criteria, it is recommended that the rate of separation of the heads of the tensile test machine not exceed 0.

The material shall conform awtm the chemical composition requirements. Sustainable V398 Goals and standardisation, how do they connect? Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

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. Combining values from the two systems may result in adtm with the specification. If, however, the presence of other elements is suspected or indicated in amounts greater than the speci?

Sampling, Testing, and Conformance Criteria Combining values from the two systems may result in nonconformance with the speci? 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.

Elongation measurements are not aetm for wire less than 0. Aluminum-alloy corresponds to uni? Diameter and Permissible Variations Slight surface checks shall not consititute cause for rejection.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. NOTE 3—The speed of testing can affect the results of the tensile strength and elongation test.

Aluminum-alloy corresponds to unified numbering system alloy A in accordance with Practice E Last previous edition B — NOTE 4—Relationships that may be useful in connection with the values of electrical resistivity are shown in Table asmt.

Valid Buy this standard. Tensile properties such as tensile strength and elongation and bending properties shall be v398 via a tension test and bending test, respectively. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

The value of 0. This specification covers aluminum-alloy T81 round wire which are solution heat-treated, cold worked, and artificially aged for electrical purposes. What is a 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.

Please note that the selected standard is invalid. Should any part of the fracture take place outside the elongation gage lines, or if examination of the tensile specimen indicates a? Joints may be made in the drawing stock or wire after heat treatment and prior to?
