Crimp terminal, wire connector, electrical connector, cable lug, cable terminal, wire terminal etc., is widely use is various industry. The quality of a crimp joint depends on the strength of the joint as well as its electrical conductivity.

Pull-force testing (a crimp pull test) is a destructive test for crimped wire connections. It measures the tensile force to separate a crimped terminal from its conductor. In the test, one end of the wire is secured, and a constant axial pull is applied. The force increases until the terminal pulls off or the wire breaks, and the peak force at failure is recorded to indicate crimp quality. Pull testing also ensures good electrical contact (metal-to-metal) at the terminal, preventing poor connections. A repeatable pull test also helps calibrate the crimping equipment.

Crimp joint testing can ensure the integrity of the final product. In general, wire connection lug testing can be broken into two categories; destructive pull testing and non-destructive pull testing. These tests both aim to determine a tensile force that the test wire can withstand. To meet the requirements of standard specifications, the tensile force that a wire can withstand must be greater than the minimum tensile strength defined by the standard.
