European foreword
This document (EN 13617-2:2021) has been prepared by Technical Committee CEN/TC 393 “Equipment
for storage tanks and for filling stations”, the secretariat of which is held by DIN.
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 2022, and conflicting national standards shall be
withdrawn at the latest by March 2024.
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 13617-2:2012.
In comparison with the 2012 edition, the following significant changes were made:
— safe breaks for aqueous urea solution added;
— Table 1 corrected to ensure compatibility between components according to EN 13012:2021,
th
— the production acceptance tests are modified to test at least every 500 unit;
— the liquid compatibility preconditioning fluid for fuel safe breaks is defined in EN 13617-1.
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 2014/34/EU.
For relationship with EU Directive, see informative Annex ZA, which is an integral part of this document.
EN 13617 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 and
dispensers.
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.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
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 subdivision Group IIA according to EN ISO/IEC 80079-20-1 and also
aqueous urea solution according to ISO 22241-1.
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 equipment 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.
