EN 13922:2003 (E)4IntroductionThe overfill prevention system prevents the maximum filling level of a compartment of a tank vehicle frombeing exceeded by interrupting the filling operation on the loading site.It is not the function of an overfill prevention system to prevent volume or weight overloading. The functionof the overfill prevention system is the final means of containing loaded product within a compartment andpreventing a dangerous condition. It is therefore of critical importance that all components have a highdegree of reliability and that all European gantries provide a compatible system with the tank trucks.Not all the components of an overfill prevention system are necessarily supplied by one manufacturer butmay include cross-compatibility parts supplied by different manufacturers/suppliers.SIST EN 13922:2003
