Petrol filling stations - Part 4: Safety requirements for construction and performance of swivels for use on metering pumps and dispensers
This European Standard specifies safety requirements for the construction and performance of swivels to be fitted to delivery hose assemblies on 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. It pays particular attention to electrical, mechanical and hydraulic characteristics of swivels.
The requirements apply to swivels at ambient temperatures from –20 °C to +40 °C with the possibility for an extended temperature range.
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 of swivels.
This European Standard is not applicable to swivels for the dispensing of any compressed gas.
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.
Tankstellen - Teil 4: Sicherheitstechnische Anforderungen an Bau- und Arbeitsweise von Drehgelenken für Zapfsäulen und druckversorgte Zapfsäulen
Dieses Dokument legt die sicherheitstechnischen Anforderungen an Bau- und Arbeitsweise von Drehgelenken fest, die in Verbindung mit Zapfstellenschläuchen an Zapfsäulen und druckversorgten Zapfsäulen 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. Es berücksichtigt insbesondere die elektrischen, mechanischen und hydraulischen Eigenschaften der Drehgelenke.
Dieses Dokument gilt für Kraftstoffe der Explosionsgruppe IIA und auch für wässrige Harnstofflösung nach ISO 22241-1.
ANMERKUNG 1 Diese Europäische Norm gilt nicht für Kraftstoffe, die nicht zur Explosionsgruppe IIA gehören.
Die Anforderungen gelten für Drehgelenke bei Umgebungstemperaturen zwischen −20 °C und +40 °C, wobei ein erweiterter Temperaturbereich möglich ist.
Dieses Dokument ist hauptsächlich auf die Gefährdungen durch Entzünden von abzufüllenden flüssigen Kraftstoffen oder deren Dämpfen anwendbar. Dieses Dokument berücksichtigt auch die elektrischen und mechanischen Gefährdungen von Drehgelenken.
Dieses Dokument gilt nicht für Ausrüstung, die für die Abgabe von verflüssigten oder verdichteten Gasen vorgesehen ist.
Stations‐service - Partie 4 : Exigences de sécurité relatives à la construction et aux performances des raccords tournants utilisés sur les distributeurs de carburants
Le présent document spécifie les exigences de sécurité relatives à la construction et aux performances
des raccords tournants destinés à être montés sur les flexibles des ensembles de mesurage et de

n’excédant pas 200 lmin-1. Il accorde une attention particulière aux caractéristiques électriques,
mécaniques et hydrauliques des raccords tournants.
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.

All electrical and non-electrical equipment and components, intended for use in potentially explosive
atmospheres, shall be designed and constructed according to good engineering practice and in
conformity with the required categories for Group II equipment to ensure avoidance of any ignition
source. To classify the category/EPL of the equipment it shall be subjected to an ignition hazard

Materials used in the construction shall be chemically and dimensionally stable under known service
conditions. Materials likely to come into contact with fuels in both liquid and vapour phases shall be
resistant to attack by these fuels. Conformity shall be demonstrated by manufacturer's declaration and
by the tests detailed in Annex A.
Light alloys when used shall conform to EN IEC 60079-0:2018, 8.3. If other specifications for explosion
protected equipment impose more stringent requirements then the more stringent requirement shall
apply.
All components shall be of corrosion resistant material or shall be provided with a corrosion resistant
protective coating.
Outside surfaces likely to be handled shall be free of sharp edges.
If protective covers are fitted they shall be constructed so that they allow ventilation and evaporation of
fuel even if some shrinkage occurs. They shall not affect the performance of the swivels.
The sealing surfaces of the connection threads shall be designed such that they are suitable for use with
an enclosed O-ring or flat gasket.
5.2 Connection threads
Swivels without a vapour recovery path shall use parallel threads in accordance with EN ISO 228-1:2003.

5 Construction
5.1 General
All electrical and non-electrical equipment and components, intended for use in potentially explosive
atmospheres, shall be designed and constructed according to good engineering practice and in
conformity with the required categories for Group II equipment to ensure avoidance of any ignition
source. To classify the category/EPL of the equipment it shall be subjected to an ignition hazard
assessment in accordance with 5.2 of EN ISO 80079-36:2016.
Materials used in the construction shall be chemically and dimensionally stable under known service
conditions. Materials likely to come into contact with fuels in both liquid and vapour phases shall be
resistant to attack by these fuels. Conformity shall be demonstrated by manufacturer's declaration and
by the tests detailed in Annex A.
Light alloys when used shall conform to EN 60079-0:2012, 8.3. If other specifications for explosion
protected equipment impose more stringent requirements then the more stringent requirement shall
apply.
All components shall be of corrosion resistant material or shall be provided with a corrosion resistant
protective coating.
Outside surfaces likely to be handled shall be free of sharp edges.
If protective covers are fitted they shall be constructed so that they allow ventilation and evaporation of
fuel even if some shrinkage occurs. They shall not affect the performance of the swivels.
The sealing surfaces of the connection threads shall be designed such that they are suitable for use with
an enclosed O-ring or flat gasket.
5.2 Connection threads
Swivels without a vapour recovery path shall use parallel threads in accordance with EN ISO 228-1.
The connection thread dimensions shall be in accordance with Table 1
