Petrol filling stations - Part 2: Safety requirements for construction and performance of safe breaks for use on metering pumps and dispensers
This European Standard specifies safety requirements for the construction and performance of safe breaks to be fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels into the tanks of motor vehicles, boats and light aircraft and into portable containers at flow rates up to 200 l min-1.
The requirements apply to safe breaks at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range.
It pays particular attention to electrical, mechanical and hydraulic characteristics of, and electrical apparatus incorporated within or mounted on, the safe break.
This European Standard applies mainly to hazards related to the ignition of liquid fuels being dispensed or their vapour. This European Standard also addresses electrical and mechanical hazards.
NOTE 1 This European Standard does not apply to equipment for use with liquefied petroleum gas (LPG) or liquefied natural gas (LNG) or compressed natural gas (CNG).
NOTE 2 Fuels other than of Explosion Group IIA are excluded from this European Standard.

Dieses Dokument legt die sicherheitstechnischen Anforderungen an Bau und Arbeitsweise von Abreißkupplungen an Zapfsäulen und druckversorgten Zapfsäulen fest, die an Tankstellen installiert werden für die Abgabe von flüssigen Kraftstoffen und wässriger Harnstofflösung in Tanks von Kraftfahrzeugen, Booten und Leichtflugzeugen sowie in tragbare Behälter bei Durchflussraten von bis zu 200 l · min−1.
Dieses Dokument gilt für Kraftstoffe der Explosionsgruppe IIA sowie für wässrige Harnstofflösung nach ISO 22241-1.
ANMERKUNG Diese Europäische Norm gilt nicht für Kraftstoffe, die nicht zur Explosionsgruppe IIA gehören.
Die Anforderungen gelten für Abreißkupplungen bei Umgebungstemperaturen zwischen –20 °C und +40 °C, wobei ein erweiterter Temperaturbereich möglich ist.
Dieses Dokument berücksichtigt insbesondere die elektrischen, mechanischen und hydraulischen Eigenschaften von Abreißkupplungen und von den zugehörigen oder an ihnen angebrachten elektrischen Betriebsmitteln.
Dieses Dokument ist hauptsächlich auf die Gefährdungen durch Entzünden von flüssigen Kraftstoffen oder deren Dämpfen während des Abfüllvorgangs anwendbar. Dieses Dokument berücksichtigt auch die elektrischen und mechanischen Gefährdungen.
Dieses Dokument gilt nicht für Ausrüstung, die für die Abgabe von verflüssigten oder verdichteten Gasen vorgesehen ist.

Le présent document s'applique aux carburants du Groupe d'Explosion IIA et aussi aux solutions
aqueuses d'urée conformément à l'ISO 22241-1.
NOTE Les carburants autres que ceux du Groupe d’Explosion IIA sont exclus de la présente Norme européenne.
Les exigences s'appliquent aux raccords cassants à des températures comprises entre –20 °C et +40 °C

8 Overview of tests
Tests shall be performed in accordance with Table 4 and using the test methods of Annex A and Annex B
NOTE Pneumatic testing is potentially a much more dangerous operation than hydraulic testing.
Type tests are those tests required to evaluate conformity. Four safe breaks shall each be subjected to
the type tests as set out below.
All fuel safe breaks for type test shall be pre-conditioned according to B.2 and B.3.
All aqueous urea solution safe breaks for type test shall be pre-conditioned according to B.3.
For fuel safe breaks, the preconditioning mechanical impact test according to B.3 shall be done
immediately after removal from saturated atmosphere and shall be commenced within 30 min of removal
from saturated atmosphere. Tests B.4, B.5, B.7 to B.16 shall then be performed without delay and shall be
completed within 6 h of the commencement of the pressure test and finally in accordance with B.6.
Production acceptance tests shall be carried out on the first unit produced on a production run, the last
th
) unit during the
unit manufactured on a production run and at least every five hundredth (500
production run.
Routine tests shall be carried out on each finished safe break.

European foreword
This document (prEN 13617-2:2018) has been prepared by Technical Committee CEN/TC 393
“Equipment for tanks and filling stations”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13617-2:2012.
In comparison with the 2012 edition, the following fundamental changes were made:
— Safe breaks for aqueous urea solution added.
— Table 1 corrected to ensure compatibility between components according to EN 13012,
EN 13617-2, EN 13617-4 and EN 1360.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent
rights of which they are aware and to provide supporting documentation.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this
document.
This European Standard Petrol filling stations consists of four parts:
— Part 1: Safety requirements for construction and performance of metering pumps, dispensers and
remote pumping units;
— Part 2: Safety requirements for construction and performance of safe breaks for use on metering
pumps and dispensers;
— Part 3: Safety requirements for construction and performance of shear valves;
— Part 4: Safety requirements for construction and performance of swivels for use on metering pumps

1 Scope
This document specifies safety requirements for the construction and performance of safe breaks to be
fitted to metering pumps and dispensers installed at filling stations and used to dispense liquid fuels
and aqueous urea solution into the tanks of motor vehicles, boats and light aircraft and into portable
-1
containers at flow rates up to 200 l · min .
This document applies to fuels of Explosion Group IIA and also aqueous urea solution according to
ISO 22241-1.
NOTE Fuels other than of Explosion Group IIA are excluded from this European Standard.
The requirements apply to safe breaks at ambient temperatures from –20 °C to +40 °C with the
possibility for an extended temperature range.
This document pays particular attention to electrical, mechanical and hydraulic characteristics of, and
electrical apparatus incorporated within or mounted on, the safe break.
This document applies mainly to hazards related to the ignition of liquid fuels being dispensed or their
vapour. This document also addresses electrical and mechanical hazards.
This document does not apply to equipment dispensing compressed or liquefied gases.
