16、 13922:2003) has been prepared by Technical Committee CEN/TC 296 “Tanks for transport of dangerous goods“, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest b
17、y October 2003, and conflicting national standards shall be withdrawn at the latest by October 2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports the objectives of the framework Directives on Transport o
18、f Dangerous Goods. This European Standard has been submitted for reference into the RID and/or in the technical annexes of the ADR. Therefore in this context the standards listed in the normative references and covering basic requirements of the RID/ADR not addressed within the present standard are
19、normative only when the standards themselves are referred to in the RID and/or in the technical annexes of the ADR. Annex A is normative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard:

21、, Uncontrolled Copy, (c) BSI EN 13922:2003 (E) 4 Introduction The overfill prevention system prevents the maximum filling level of a compartment of a tank vehicle from being exceeded by interrupting the filling operation on the loading site. It is not the function of an overfill prevention system to
22、 prevent volume or weight overloading. The function of the overfill prevention system is the final means of containing loaded product within a compartment and preventing a dangerous condition. It is therefore of critical importance that all components have a high degree of reliability and that all E
23、uropean gantries provide a compatible system with the tank trucks. Not all the components of an overfill prevention system are necessarily supplied by one manufacturer but may include cross-compatibility parts supplied by different manufacturers/suppliers.

This European Standard i
25、s 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 in the range from -20 C to +50 C, subjected to norm
26、al operational pressure variations. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated reference
