Petrol filling stations - Construction and performance of automatic nozzles for use on fuel dispenser
This European Standard specifies safety and environmental requirements for the construction and performance of nozzles to be fitted to metering pumps and dispensers installed at filling stations and which are 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. The requirements apply to automatic nozzles dispensing flammable liquid fuels at ambient temperatures from -20 °C to +40 °C with the possibility for an extended temperature range. This European Standard does not apply to equipment dispensing liquefied petroleum gas nor compressed natural gas. This European Standard does not include any requirements for metering performance, such as may be specified under the Measuring Instruments Directive, nor those requirements specified under the Electromagnetic Compatibility Directive. Vapour recovery efficiency rates are not considered within this European Standard.
Tankstellen - Anforderungen an Bau und Arbeitsweise von automatischen Zapfventilen für die Benutzung an Zapfsäulen
Diese Europäische Norm legt die sicherheitstechnischen und Umweltanforderungen an den Bau und die Arbeitsweise von Zapfventilen fest, die an Zapfsäulen und druckversorgten Zapfsäulen auf Tankstellen installiert werden, und die für die Abgabe von flüssigen Kraftstoffen in Tanks von Automobilen, Booten und Leichtflugzeugen und in tragbare Behälter bei Durchflussraten bis zu 200 l·min–1 eingesetzt werden. Die Anforderungen beziehen sich auf automatische Zapfventile für die Abgabe von brennbaren flüssigen Kraftstoffen bei Umgebungstemperaturen von – 20 °C bis + 40 °C, mit der Möglichkeit einer Erweiterung des Temperatur-bereiches.
