ASTM B is a test method used to measure the tensile astk of wire connections. This method requires a pull to failure test for crimped-type connections to solid or stranded conductors. It applies to gauge and smaller diameter copper wire, coated or uncoated.

This test method is designed in two parts: Method A and Method B. Prepare a lot of test specimens of the crimp terminal crimped to a short length of wire.


For Method A, prepare 64 specimens, for Method B, prepare 94 specimens. For both methods the wire should be pulled from a group of the specimens in a tensile pull and the force compared to set requirements based on wire diameter. 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.

Your electrical test results can be compared to a standard value based on wire diameter. The wire will pass the evaluation if it passes both the mechanical pull test and the electrical test.

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.
