Quality control. Mechanical test on the quality of an electrical socket. The socket (at left) has wires leading to a control panel (at back of image). A mechanically-operated plug (at centre) which is also connected to the control panel,can be inserted into the socket to make the connection. A display unit (at upper right) is also seen. The conductivity,the force required to make the connection,and the longevity of the socket can therefore be assessed. Photographed at the Italian Quality Mark Institute,Italy | |
