This document (EN 13922:2020+A1:2022) has been prepared by Technical Committee CEN/TC 296
“Tanks for the 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 by March 2023, and conflicting national standards shall
be withdrawn at the latest by March 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes !EN 13922:2020".

The start and finish of text introduced or altered by amendment is indicated in the text by tags !".
In comparison with the 2011 edition, the following fundamental changes were made:
— safety integrity level (SIL) added;
— requirements and tests for electromagnetic compatibility (EMC) revised;
— temperature for the sensors extended to +60 °C;
— electrical requirements in 6.3.7 expanded for clarification;
— waveform signal changed to waveform pulse throughout the standard;
— Annex A tables and figures revised to reflect installed base;
— the word "peak" was added in Table A.3 before "sensor current" only for clarification;
— referred standards updated.

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 prevent volume or weight overloading. The
function of the overfill prevention system is the final means of containing the 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 European gantries provide a compatible
system with the tank-vehicles.
Not all the components of an overfill prevention system are necessarily supplied by one manufacturer
but may include cross-compatible parts supplied by different manufacturers/suppliers. However, cross-
compatibility does not mean interchangeability.
1 Scope
This document specifies the following points regarding the minimum requirements for an overfill
prevention system:
