This test method is designed in two parts: No other units of measurement are included in this standard. Your comments will receive careful consideration at a meeting of theresponsible technical committee, which you may attend. Prior to applying the pull Record the results. A universal testing machine can be used to test for B While monitoring the voltage across the connection on the oscilloscope, grasp the wire at a 8.
Referenced Documents terminal block. Link to Active This link will always route to the current Active version satm the standard. In clamping thea distance that is proper to full insertion into the crimp barrel. Last previous edition approved in as B — 00e1.
View in Fullscreen Report. Select a random sample of 10 specimens 3. Subject the remaining 30 specimens to the Compare the result forevaluation test cannot be applied with validity to manufactur- each of the production lot 9b13 specimens to the requirementing lots made with other tools or components. The following method is for inspection of production 30 astj samples.
Additional testing may be appropriate if the intended service environment presents such hazards. It also accelerates other thermally activated processes such as oxidation although their acceleration factors may be different from that of copper stress relaxation.
No other units of measurement are included in this terminal that is deformed in the crimping operation.
Tensile Pull Strength Test. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the riskof infringement of such rights, are entirely their own responsibility.
ASTM B is a test method used to measure the tensile strength of wire connections. Historical Version s – view previous versions of standard. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, astj and humidity chambers, furnaces, baths and custom solutions for unique applications.
For multiple wire crimped connections, test pull the smallest 9. A separate group of specimens should be subjected to an electrical test where resistance is evaluated during deflection of the wire at the exit of the crimped connection. astn
B — 05performed on subgroups of parts during and after the aging test 7. 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.
Originally and the electrical test.
For both methods the wire should be pulled from a group of the specimens in a tensile pull and the force compared to set ashm based on wire diameter. The crimped connection passes the Tensile Pull B — 05and subject them to the Tensile Pull Strength Test.
Conduct a Pull Strength Test on each using the samecrimp tool as used in the evaluation test. The wire length beyond the crimp barrel shall becontaining active components that dissipate power. Published by Guset User Select a random sample of 10 of the 60test, inactivate any stress relief or crimp, viz. Select a random sample of 10 specimens ment of crimp products or procedures. It applies to gauge and smaller diameter copper aetm, coated or uncoated. Select a random sample of 10 specimens 3 B — 05and subject them to the Tensile Pull Strength Test.
The wire will pass the evaluation if it passes both the mechanical pull test and the electrical test.
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. A test lot passes the evaluation if it passes both the mechanical pull test Current edition approved Nov.
The strain relief shall be disabled prior to testing the 8. Secure electrical connections shall be established and aconnection to electrical measuring devices. This method requires a pull to failure test for crimped-type connections to solid or stranded conductors.
Return the remaining 30 specimens to the oven. Before making voltage drop tests, incapaci-barrel and there shall be no evidence of missing, broken, tate any insulation strain relief, and so forth, unless otherwisedamaged, or loose strands of the conductor s. Create your own flipbook. 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.
If a failure is observed with the wire 8.
