DIN EN 13922:2011-11 EN 13922:2011 (E) 5 Introduction The overfill prevention system prevents the maximum filling level of a compartment of a tank vehicle
24、 from being 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 function of the overfill prevention system is the final means of containing loaded product within a compartment and pre
25、venting a dangerous condition. It is therefore of critical importance that all components have a high degree 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 manufac
26、turer but may include cross-compatibility parts supplied by different manufacturers/suppliers. DIN EN 13922:2011-11 EN 13922:2011 (E) 6 1 Scope This European Standard specifies the following points regarding the minimum requirements for an overfill prevention system: functions; major components; cha
27、racteristics; test methods. This European Standard is applicable to overfill prevention systems for liquid fuels having a flash point up to but not exceeding 100 C, excluding liquefied petroleum gas (LPG). The requirements apply to overfill prevention systems suitable for use at ambient temperatures
28、 in the range from - 20 C to + 50 C, subjected to normal operational pressure variations. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition
