No other units of measurement are included in this terminal that is deformed in the crimping operation. It also accelerates other thermally activated processes such as oxidation although their acceleration factors may be different from that of copper stress relaxation.
Prior to applying the pull Record the results. The crimped connection passes the Tensile Pull The grip or supportshall, as designed, mechanically secure asstm support the wire 9. You can publish your book online for free in a few minutes! Published by Guset User It applies to gauge and smaller diameter copper wire, coated or uncoated. A test lot passes the evaluation if it passes b931 the mechanical pull test Current edition approved Nov.
pull strength for wire/cable terminal, lugs, connector ASTM B – Tension – United Test
Select a random sample of 10 specimens ment of crimp products or procedures. Method A and Method B. Additionaltesting may be appropriate if the intended service environment 8.
In Method B, additional pull tests are performed on subgroups of parts during and after the aging test to provide information on progressive degradation in performance. Prepare a lot b9113 test specimens of the crimp terminal crimped to a short length of wire. 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 asstm conductor s.
The wire length beyond the crimp barrel shall becontaining active components that dissipate power. Observe whether the strength declines with aging. An example of such an acceptance requirement is shown in Appendix X1. Referenced Documents terminal block. Last previous edition approved in as B — 00e1.
In Method B, additional pull tests areapproved in Record the peak-to-peak for 16, 18, 20, and gauge wire crimps or results. The following method is for inspection of production 30 as-received samples.
Subject the remaining 30 specimens to the Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the aboveaddress or at phonefaxor service astm. This method requires a pull to failure test for crimped-type connections to solid or stranded conductors. 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.
Interpretation of Results The strain relief shall be disabled prior to testing the 8. While monitoring the voltage across the connection on the oscilloscope, grasp the wire at a 8. After the evaluation is completed, if any change in the system parts is made, the system should be reevaluated using the same procedures.
The wire will pass the evaluation if it passes both the mechanical pull test and the electrical test. A number in parentheses indicates the year of last reapproval. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Results of an conditions as used in the evaluation test. Select a random sample of 10 specimens 3. This environment is similar to that seen in a wide range of electronic systems operating indoors containing active components that dissipate power. Position them in the 9. The test is mm 8 in. 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.
Keywords24 31 44 10 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.
ASTM B913 Testing Crimped Wire Connections
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. The oventhe system should be reevaluated using the same procedures.
v913 Create your own flipbook. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval. Observe and record the maximum voltage wave peak to 8. ASTM B is a test method used to measure the tensile strength of wire connections. If you feel that your comments have not received a fair hearing you shouldmake your views known to the ASTM Committee on Standards, at the address shown below.
Originally and the electrical test.

Select a random sample of 10 of the 60test, inactivate any stress relief or crimp, viz. As a consequence, the conductor surfaces are placed under compression by the crimp terminal and areas of contact are established between the conductor and the crimp barrel.
Unless otherwise agreed upon Spring clipsis capable of maintaining the contact between the conductor often used with 16 to gauge wire are not adequate; a higherand crimp barrel so that a stable electrical connection is force clamp is needed.
