Withdrawal Test for Crimp-Style Terminals
Crimp-style terminals are types of connector terminals attached to electrical wire ends. They are fastened by applying physical pressure to the wire and the terminal. They are used as an alternative to soldering in order to improve workability.
Withdrawal tests are performed with the Autograph to evaluate fastening strength between the wire and the terminal. Terminal parts may be damaged if gripped directly, so they are sometimes pinched using an L-shaped metal piece (designed to prevent withdrawal) as a cushioning material.
