BS EN 13922:2020 pdf free.Tanks for transport of dangerous goods – Service equipment for tanks – Overfill prevention systems for liquid fuels.
This document specifies the following points regarding the minimum requirements for an overfill prevention system:
— functions;
— major components;
— characteristics;
— test methods.
This document 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).
NOTE Vapour path detection is not part of this standard but can be provided as an option.

4 Functions
4.1 To prevent overuulling of the tank-vehicle’s compartment by providing a fail-safe output to a gantry control system.
4.2 To provide a failsafe monitored earthing connection from the gantry to the tank-vehicles shell via a bonding connection to the tank-vehicle’s chassis.
4.3 To provide visual Indication of the status of the overfill prevention system.
5 Major components
5.1 Tank-vehicle mounted equipment
The following equipment shall be installed on the tank-vehicle as a minimum:
— one sensor or sensor circuit per compartment;
— one 10 pin socket;
— wiring to tile sensors;
— earthing provision.
5.2 Equipment fitted at the gantry
The overfill prevention equipment mounted on the tank truck is operable when the following equipment is installed at a loading gantry:
— overfill prevention controller;
— one 10 pin plug and cable for connection to tank-vehicle socket.
5.3 Optional equipment
The overfill prevention system can provide the vapour collection detection safety interlock which prevents loading unless the vapour collection hose is connected to the tank-vehicle and the vapour transfer valve(s) is (are) open.BS EN 13922 pdf download.
