This document is applicable to:
- delivery pipes from tanks to dispensers, including positive pressure, vacuum suction and siphon modes;
- fill pipes from road tankers to tanks;
- vapour recovery and vent pipework;
- pipework for secondary containment;
- fittings.
It does not apply to pipework for use with liquefied petroleum gas.

Ta dokument določa zahteve za podzemne cevovodne sisteme, ki se uporabljajo za prenos tekočih goriv in njihovih hlapov na bencinskih črpalkah. Podane so minimalne zahteve glede zmogljivosti, ki zajemajo primernost za namen, varnost in varstvo okolja.
Ta dokument se nanaša na cevovode iz termoplastov, ki lahko vključujejo določeno stopnjo ojačitve, in na prilagodljive kovinske cevovode. Ne velja za vlakno ojačane termosete, običajno imenovane plastična masa ojačana s steklenimi vlakni (GRP), niti za toge kovine.
Ta dokument se uporablja za:
- cevi za dostavo od rezervoarjev do razdelilnikov, vključno z načini pozitivnega tlaka, vakuumskega sesanja in sifona;
- cevi za polnjenje od cestnih cistern do rezervoarjev;
- cevovode za vračanje hlapov in odzračevalne cevovode;
- cevovode za sekundarno zadrževanje;
- spoje.
Ne velja za cevovode za uporabo s utekočinjenim naftnim plinom.

Overview
SIST EN 14125:2025/oprA1:2026 is a key Slovenian standard specifying the requirements for thermoplastic and flexible metal pipework systems designed for underground installation at petrol filling stations. The standard ensures that pipework used for the transfer of liquid fuels and vapours meets vital criteria for fitness for purpose, safety, and environmental protection. It applies to both reinforced and unreinforced thermoplastic pipes and to flexible metal pipes, covering a range of applications associated with underground petrol station infrastructure.
This standard is not applicable to fibre reinforced thermosets (such as glass fibre reinforced plastic, GRP) or to rigid metallic pipework. It also excludes pipework used with liquefied petroleum gas (LPG).
Key Topics
SIST EN 14125:2025/oprA1:2026 addresses several core aspects of underground pipework for petrol filling stations:
- Performance Requirements: Mandatory performance criteria to guarantee pipework reliability, including crush resistance, recovery after deformation, and durability under various operating conditions.
- Safety and Environmental Protection: Provisions that help minimize risks related to leaks, spills, or vapour emissions, thereby safeguarding human health and the environment.
- Applicable Materials: Focuses on thermoplastics (including reinforced forms) and flexible metals, which are widely used for their corrosion resistance and ease of installation.
- System Components: Covers delivery pipes (tank to dispenser), fill pipes (road tanker to tank), vapour recovery and vent pipes, secondary containment, and fittings.
- Test Modifications: Specific amendments, such as updated crush test recovery requirements and clarified high-temperature test procedures.
Applications
This standard is essential for stakeholders involved in designing, installing, and maintaining petrol filling station infrastructure:
- Fuel Transfer Systems: Applies to underground pipes conveying liquid fuels from storage tanks to dispensers using positive pressure, vacuum suction, or siphon methods.
- Tank Filling: Governs the pipework for delivering fuels from road tankers into underground storage tanks at service stations.
- Vapour Recovery and Venting: Standardizes pipework involved in controlling fuel vapour emissions and ensuring safe venting practices.
- Secondary Containment: Addresses piping used for additional environmental protection, reducing the risk of soil contamination from leaks.
- Fittings and Connections: Includes requirements for joints and fittings vital for system integrity.
Businesses such as construction companies, fuel retailers, and engineering firms benefit from implementing SIST EN 14125:2025/oprA1:2026 by ensuring compliance, promoting safety, and meeting environmental regulations. The use of compliant pipework enhances operational durability and simplifies maintenance at petrol filling stations.
Related Standards
For a holistic approach to underground pipework and fuel system safety, consider the following related standards:
- EN 14125: The core European standard for underground thermoplastic and flexible metal pipework at service stations.
- EN 12285: Covers workshop-fabricated steel tanks for underground storage of fuels.
- EN 13616: Relates to overfill prevention devices for use at filling stations.
- EN 12576: Specifies requirements for pipe connections and jointing in petroleum supply systems.
- ISO 9001: Offers general quality management guidance for manufacturing and installation processes.
Adherence to SIST EN 14125:2025/oprA1:2026 supports robust, environmentally responsible, and regulatory-compliant fuel infrastructure. This facilitates safer operations, improved life cycle performance, and greater peace of mind for operators and the public.
