Of the many steps in the process of assembling a wire harness, testing the crimped terminal is a crucial one. If the terminal hasn’t been properly attached to the end of the wire, it can cause the wire and eventually the entire wire harness to fail. Most manufacturers use pull testing to assess crimped connections and ensure that terminals are properly attached.
Pull testing measures the amount of tensile force required to separate a crimped terminal from a wire. To minimize the chance of product failure, it should take a good amount of force to do that.
