Overview

The prEN 12514-1 standard, developed by the European Committee for Standardization (CEN), sets forth crucial safety requirements, testing protocols, and terminology for parts used in supply systems for consuming units that utilize liquid fuels. This European Standard applies specifically to the automatic supply systems responsible for transferring liquid fuel from one or more tanks to one or more consuming units, covering all components between the tank connections and the burner or consumer units, including directly series-connected shut-off devices.

This standard is essential in ensuring safety, reliability, and regulatory compliance for liquid fuel supply systems across diverse industrial and commercial applications. It supersedes previous editions and aligns with EU regulations such as the Construction Product Directive (CPD), Measuring Instruments Directive (MID), and Machinery Directive (MD).

Key Topics

• Terminology and Definitions: Comprehensive clarification of terms related to parts, pipelines, feed pump control and safety devices, pressure, temperature, flow, and other relevant aspects of liquid fuel supply systems.

• General Requirements: Specifies material and construction quality, pressure strength, temperature tolerances, fuel compatibility, nominal lifespan, fireproof and flood-proof components, and electrical safety standards.

• Marking, Packaging, and Instructions: Guidelines on proper marking for traceability and safety, packaging standards to prevent damage during transport and storage, and instructions for installation, maintenance, and operation ensuring user safety.

• Testing Procedures:

  • Pressure strength and vacuum tests to validate endurance and leak prevention.
  • External leak-tightness tests to ensure containment integrity.
  • Visual and dimensional inspections for manufacturing accuracy.
  • Fireproof and flood-proof part testing to enhance resilience.

• Material Standards: Annexes provide detailed normative specifications for metallic and thermoplastic materials used in supply system parts, including type testing and factory production control measures.

• Conformity Evaluation System: Protocols for initial and periodic type testing, factory inspections, quality control, and certification methods to ensure ongoing compliance with standard requirements.

Applications

The prEN 12514-1 standard is pivotal to manufacturers, installers, and safety inspectors involved in:

• Designing and producing automatic liquid fuel supply systems for residential, commercial, and industrial burners.
• Assessing and certifying safety compliance of fuel supply components, including valves, pumps, pipelines, and shut-off devices.
• Implementing maintenance programs that safeguard against material fatigue, corrosion, and failure under operational pressure and temperature ranges.
• Meeting European regulatory requirements to enable market access across EEA countries while ensuring sustainable and safe fuel supply infrastructure.
• Providing a unified terminology and testing framework for engineers and technicians working on liquid fuel burner installations and fuel handling systems.

Related Standards

• prEN 12514-2: Safety requirements and tests for feed pumps, control and safety devices, and service vessels relevant to liquid fuel supply systems.
• prEN 12514-3: Safety requirements and tests for valves and meters used within liquid fuel supply circuitry.
• prEN 12514-4: Safety requirements and tests for pipelines and associated parts within fuel supply networks.
• Construction Product Directive (89/106/EEC): Addresses safety and performance essential requirements linked to construction products including fuel supply components.
• Measuring Instruments Directive (2004/22/EC): Regulations relating to accuracy and reliability of instruments such as meters in fuel systems.
• Machinery Directive (2006/42/EC): Covers safety requirements for machinery components, including fuel supply equipment.

Adherence to prEN 12514-1 ensures liquid fuel supply systems' parts are designed, tested, and certified to meet rigorous safety and functional standards, providing confidence to manufacturers, service providers, and end-users alike. This facilitates safe operation, environmental protection, and conformity with EU legal frameworks within the fuel supply industry.
