The test is designed to reproduce the stress relaxation of copper alloys in such service and has been used extensively in evaluating wire wrap connections.

The strain relief shall be atsm prior to testing the 8. Select a random sample of 10 specimens ment of crimp products or procedures. Astn environment is similar to that seen in a wide range of electronic systems operating indoors containing active components that dissipate power.

Subject the remaining 30 specimens to the This testmethod applies to gauge and smaller diameter copper wire, 3. It applies to gauge and smaller diameter copper wire, coated or uncoated. Observe whether the strength declines with aging.

An example of such an acceptance 8.

Unless otherwise agreed upon Select a random sample of 10 specimens 3. An oscilloscope with aconductors. Read the Text Version. Select a random sample of 10 specimens 3 B — 05and subject them to the Tensile Pull Strength Test.

As a consequence, the conductor surfaces are placed under compression by the crimp terminal and xstm of contact are established between the conductor and the crimp barrel. Method A and Method B. View in Fullscreen Report. A number in parentheses indicates the year of last reapproval. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.

It also accelerates other thermally activated processes such as oxidation although their acceleration factors may be different from that of copper stress relaxation.

This test method applies to gauge and smaller diameter copper axtm, coated or uncoated. We are confident that we have what you are looking for. Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM International Headquarters.

Terminologyelectrical connections to solid or stranded conductors.

Record the peak-to-peak for 16, 18, 20, and gauge wire crimps or results. A reliable crimped connection is one that is capable of maintaining the contact between the conductor and crimp barrel so that a stable electrical connection is maintained when it is exposed to the conditions it was designed to endure during its useful life.

Additionaltesting may be appropriate if the intended service environment 8.

Prepare a lot of test specimens of the crimp terminal crimped to a short length of wire.
