Overview

EN 15268:2008 is a CEN (European) standard that defines safety requirements for the construction of submersible pump assemblies used at petrol filling stations. It applies to submersible pumps used with fuel dispensers for dispensing liquid fuels specified in EN 228 (petrol) and EN 590 (diesel) into motor vehicle, light aircraft, boat and portable container tanks. The standard covers design, installation, commissioning, use and maintenance for equipment intended for ambient temperatures between –20 °C and +40 °C, with additional measures negotiable outside that range.

Key technical limits:

• Maximum working pressure: 350 kPa (3.5 bar)
• Maximum motor power: 7 kW
• Maximum supply voltage: 500 V
• Explosion-protection classes: IIA T3 and IIB T4

Noise is not considered a significant hazard in the scope of this standard. Mobile equipment and metering performance requirements (e.g., Measuring Instruments Directive) are excluded.

Key topics and technical requirements

• Risk assessment and hazard analysis: Formal documented analysis of ignition sources and other hazards (EN 13463-1 referenced).
• Explosion prevention & protection: Requirements for electrostatic control, capacitance discharge limits and ignition control for parts exposed to explosive atmospheres.
  • Capacitors must discharge to ≤ 0.2 mJ within 10 s after disconnection.
  • External junction boxes must meet equipment category 2 requirements.
  • Connectors and plugs in ignition-capable circuits are treated as normally sparking unless they require ≥ 15 N separating force or are mechanically locked.
• Materials compatibility: All fuel-exposed parts must resist chemical attack by the intended fuels and vapours.
• Pressure safety: Pressurised systems must include a pressure relief device limiting pressure to ≤ 350 kPa and be designed for the maximum working pressure.
• Electrical safety: Conformance with EN 60204-1 for electrical equipment and EN 60034-1 for motors; earth bonding and considerations for converter-fed motors (bearing currents, overvoltage).
• Leakage & containment: Design to ensure no leakage under normal operating conditions; pressurised parts sized appropriately.
• Scope of hazards: Mechanical (pump dropping), thermal, electrical, material hazards and foreseeable misuse are addressed.

Applications and who uses it

EN 15268 is intended for:

• Manufacturers of submersible pumping units, manifold and column pipe assemblies
• Petrol filling station designers and contractors
• Installation and commissioning engineers
• Safety and compliance officers in fuel retail and storage industries
• Notified bodies and test laboratories assessing conformity to EU directives

Practical uses include designing safe submersible pump assemblies for forecourts, selecting compliant materials and components, specifying electrical protection and explosion prevention measures, and preparing technical documentation for conformity assessment.

Related standards

Key normative references and related standards cited in EN 15268 include:

• EN 228, EN 590 (fuel specifications)
• EN 13463-1, EN 13463-6 (non-electrical equipment in explosive atmospheres)
• EN 60079 series (explosive atmospheres)
• EN 60204-1, EN 60034-1 (electrical safety and motors)
• EN ISO 12100 (risk assessment and machinery safety)

Using EN 15268 helps ensure compliant, safe submersible pump assemblies for petrol filling stations, aligning design and operational practices with European safety and explosion-protection expectations.
