European Fuel Dispenser Standards

European fuel dispenser standards are governed by a combination of EN (European Norms) and ATEX directives, ensuring safety, accuracy, and environmental compliance. Below is a synthesis of core standards and their requirements:


1. EN 13012:2021

Title: Petrol Filling Stations - Construction and Performance of Automatic Nozzles for Use on Fuel Dispensers
Scope:

  • Applies to automatic nozzles for dispensing liquid fuels (e.g., petrol, diesel) and aqueous urea solutions at flow rates ≤200 L/min.

  • Covers safety, environmental, and performance requirements.

Key Requirements:

  • Leakage Control: Nozzle seals must prevent fuel leakage under pressure (tested at 400 kPa for 30 seconds).

  • Vapor Recovery: Compatible with Stage II vapor recovery systems (if applicable).

  • Material Stability: Components must resist corrosion from fuels (tested per ISO 9328).

  • Electrical Safety: Compliance with EN 60079-14 for explosion-proof wiring .


2. EN 14678-2:2012

Title: LPG Equipment and Accessories for Automotive Filling Stations - Part 2: Components Other Than Dispensers
Focus:

  • Shear Valves: Mandatory installation to prevent fuel spills during collisions.

  • Swivels: Ensure leak-proof connections between hoses and dispensers.

  • Shear Valves: Must activate at ≤500 N force to disconnect fuel flow.

  • Pressure Testing: Components must withstand 1.5× maximum working pressure for 10 minutes .


3. EN 13617-3:2012

Title: Petrol Filling Stations - Part 3: Safety Requirements for Construction and Performance of Swivels
Scope:

  • Applies to swivels used in fuel dispensers for vehicles, boats, and portable containers.

  • Electrical Safety: Enclosures must meet IP54 protection against dust/water.

  • Leakage Limits: Internal leakage ≤4 L/hour, external leakage ≤1 L/hour during pressure tests .


4. ATEX Directive 2014/34/EU

Title: Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres
Scope:

  • Mandatory for fuel dispensers in explosive environments (e.g., petrol stations).

  • Equipment Classification:

    • Zone 1: Devices must be Ex ia (intrinsically safe) or Ex ib (increased safety).

    • Zone 2: Ex nA (non-sparking) or Ex ec (energy-limited) acceptable.

  • Marking: CE + Ex symbol (e.g., Ex ia IIB T4) .


5. EN 60079-14:2019

Title: Explosive Atmospheres - Part 14: Electrical Installations Design, Selection, and Erection
Focus:

  • Guidelines for installing explosion-proof electrical systems in fueling stations.

  • Wiring: Use of armored cables for hazardous areas.

  • Grounding: Resistance ≤10 Ω for static discharge prevention.


6. EN 12891:2017

Title: Petrol Filling Stations - Safety Requirements for Fuel Dispensers
Scope:

  • Comprehensive safety standards for dispenser design and operation.

  • Anti-Tampering: Mandatory self-locking mechanisms to prevent unauthorized calibration.

  • Display Accuracy: Fuel quantity must be legible from 2 m distance under sunlight.


7. EN 16709:2015

Title: Automotive Fuels - High FAME Diesel (B20 and B30) - Requirements and Test Methods
Scope:

  • Applies to biodiesel blends (B20/B30) in dispensers.

  • Corrosion Resistance: Components must pass 720-hour salt spray tests.

  • Material Compatibility: Hoses and seals must resist biodiesel degradation.


Compliance and Certification

  • CE Marking: Mandatory for all fuel dispensers sold in the EU.

  • ATEX Certification: Required for explosion-proof components.

  • Testing Bodies: Accredited labs (e.g., TüV, SGS) perform conformity assessments.


Accessing Standards

  1. Official Sources:

    • Purchase from CEN (European Committee for Standardization) or BSI Group.

  2. Third-Party Translations:

    • Engage ISO-certified translators for technical accuracy (e.g., terms like "Ex ia IIB T4").

    • China fuel dispenser (https://www.cnruijia.com),professional fuel dispenser manufacturer.


Key Differences from Non-European Standards

AspectEN/ATEX StandardsNon-European (e.g., US/China)
Explosion ProtectionATEX directive with zone classificationsNEC or GB/T 22380 (simplified zones)
Material TestingFocus on fuel compatibility (e.g., biodiesel)Emphasis on mechanical durability
CertificationCE + ATEX marksUL, CPA, or CCC
