European foreword
This document (EN 13617-3:2021) 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withdrawn at the latest by March 2024.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 13617-3:2012.
In comparison with the 2012 edition, the following significant changes were made:
— shear valves for aqueous urea solution added;
— testing for vapour shear valves further differentiated from testing for fuel shear valves. Tests B.16,
and B.17 are introduced;
— fire resistance test B.14 and B15 introduced and pass/fail criteria defined in Table 3;
— the liquid compatibility preconditioning fluid for shear valves 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 and environmental requirements for the construction and performance
of shear valves to be fitted to metering pumps, dispensers, and/or satellite delivery systems installed at
petrol 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 containers at flow rates up to 200 l · min
This document applies to fuels and their vapours 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 shear valves at ambient temperatures from −20 °C to +40 °C with the
possibility for an extended temperature range.
This document pays particular attention to mechanical and hydraulic characteristics.
This document does not apply to equipment dispensing compressed or liquefied gases.
