European foreword
This document (CEN/TR 15120:2022) has been prepared by Technical Committee CEN/TC 296 “Tanks
for the transport of dangerous goods”, the secretariat of which is held by AFNOR.
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 CEN/TR 15120:2013.
In comparison with the previous edition, the following technical modifications have been made:
Total revision including:
— Redraft to reflect current format rules;
— Development of recommendations on:
— New mixtures and substances;
— Protection against electrostatic hazards;
— The difference between type 1 and type 2 tank-vehicle designs;
— Vapour collection breather device operation;
— Vapour Manifold Vent Valve operation;
— Vapour manifold design, fabrication, and test;
— Revision of annexes.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
Introduction
This document provides guidance and recommendations to enable the transfer of product and vapour
between the loading gantry, the tank-vehicle, and the service station.
The European Parliament and Council Directive 94/63/EC (VOC Directive) [1] requires operators to
ensure that petroleum vapours are not emitted into the atmosphere during loading and unloading. The
recommendations and guidance given in this document are intended to assist users in meeting the
requirements of this Directive.
This document acknowledges that, for historical, climatic, and logistical reasons, alternative technical
solutions are commonly used nationally and in the Arctic Region.
1 Scope
This document gives guidance and recommendations for loading at terminals and discharge at service
stations or customer premises of tank-vehicles transporting dangerous substances of Class 3 of ADR –
European Agreement concerning the International Carriage of Dangerous Goods by Road [2] –
(flammable liquids) which have a vapour pressure not exceeding 110 kPa at 50 °C and petrol, and which
have no sub-classification as toxic or corrosive.

4 Bottom loading gantry function and operation
4.1 Gantry loading equipment
4.1.1 General
It is recommended that arrangements to permit loading of a tank-vehicle, equipped according to this
document, are available to all gantries on loading facilities and at least one at each loading facility in arctic
regions.
NOTE The arctic region comprises Denmark, Finland, Iceland, Norway and Sweden.
4.1.2 Overfill prevention – gantry meter pre-set
The primary overfill prevention system is provided by the pre-setting of the gantry loading meter by the
tank-vehicle loader for each tank-vehicle compartment, separately, before it is loaded.
Therefore, it is recommended that bottom loading is only be permitted at gantries fitted with such pre-
set meters to limit the volume loaded into each tank-vehicle compartment.
NOTE 1 Overfill is the filling of a tank-vehicle or one or more of its compartments to the extent that the total
volume loaded into a compartment exceeds the maximum permitted volume for transport (see Annex D).
NOTE 2 Overloading is the loading of a tank-vehicle such that its total weight exceeds that permitted by local
road regulations, or the load imposed by one or more axles exceeds the local maximum authorized weight for that
axle and for a semi-trailer, when its coupling to the tractor is loaded to an extent that it exceeds its design load.
4.1.3 Overfill prevention – overfill prevention system (OPS)
The secondary overfill prevention system is provided by the overfill prevention system. The secondary
system is a safety system which comes into operation when the primary system fails to operate.
To ensure interoperability, it is recommended that the gantry-based components of the overfill
prevention system conform to EN 13922 [3].
Annex A shows the location envelope of the tank-vehicle socket.
