3 terms and definitions
Column F terms and definitions apply to this standard.
3.1
Overfill prevention system
A system consisting of an anti-overflow sensor and an anti-overflow socket connected by a cable.
3.2
Overfill prevention optic sensor
A sensor installed at the top of the tank to determine whether the liquid level in the tank exceeds a specified height.
3.3
Overfill prevention socket
Interface for anti-overflow system and external connection.
