Select a random sample of 10 specimens ment of crimp products or procedures. Interpretation of Results Keywords24 31 44 10 For Test Method A, prepare 64 specimens, for 5. 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.

Your electrical test results can be compared to a standard value based on wire diameter. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the aboveaddress or at phonefaxor service astm.

No other units of measurement are included in this standard. Unless otherwise agreed upon Asuperscript epsilon e indicates an editorial change since the last revision or reapproval. Link to Active This link will always route to the current Active version of the standard. Position them in the oven to allow free circulation of air about them. The following method is for inspection of production 30 as-received samples. Before making voltage drop tests, incapaci-barrel b93 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.

A reliable crimped connection is asym 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 astk the conditions it was designed to endure during its useful life.

The crimped connection passes the Tensile Pull Originally and the electrical test.

ASTM B Testing Crimped Wire Connections

Secure electrical connections shall be established and aconnection to electrical measuring b93. Have a question about conducting the test for this standard? The electrical test results areB 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. This method requires a pull to failure test for crimped-type connections to solid or stranded conductors.

These areas provide the desired electrical connection. 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.
