Overview: This plug pull‑out testing machine is used to evaluate the bonding strength between the plug blade and the conductor, as well as the conductor’s resistance to pull‑out forces, employing an impact weight for the pull‑out test. Test Method: The plug is secured within the socket, with the conductor’s free end attached to the impact hammer rod. A weight is then suspended to perform rotational tests and current‑withstand tests on the E‑terminal (ground terminal). Test Standard: This test complies with standards such as UL‑817.
