Overview
SIST EN 17339:2025/oprA1:2026 establishes the minimum requirements for materials, design, construction, prototype testing, and routine manufacturing inspections of transportable gas cylinders and tubes made from hoop wrapped and fully wrapped carbon composite materials intended for compressed hydrogen. Developed by the Slovenski inštitut za standardizacijo (SIST), this standard applies to high-pressure composite cylinders (Types 2, 3, and 4), which are crucial for the safe storage and transportation of hydrogen in industries such as energy, mobility, and process engineering.
This standard aims to harmonize the safety and performance benchmarks across the European market for hydrogen storage solutions, ensuring reliability and compliance for manufacturers and end-users.
Key Topics
- Scope of Applicability:
- Fully wrapped composite cylinders (Type 3 and Type 4)
- Hoop wrapped composite cylinders (Type 2)
- Applications for cylinders with test pressures not less than 300 bar and up to 1,000 bar working pressure
- Maximum water capacity of 3,000 liters and p x V value not exceeding 1,000,000 bar·l
- Material and Design Requirements:
- Use of carbon fiber reinforcements with non-metallic liners (Type 4) or seamless metallic liners (Type 2 & 3)
- Incorporation of optional protective layers such as glass fiber on the cylinder’s external surface
- Construction and Manufacturing:
- Detailed provisions related to components, including possible permanent additions such as neck rings, foot rings, and dome protectors
- Guidelines for prototype and design variant testing
- Performance Testing:
- Blunt impact resistance at specific cylinder locations
- Hydraulic pressurizing procedures at varying temperatures (e.g., 65°C and –40°C) and under cyclic pressures
- Regular production testing of carbon fiber and matrix properties
- Quality Assurance:
- Certification procedures for type testing and design variant testing to ensure consistency and traceability
Applications
The standard is essential in several key application areas:
- Hydrogen Storage and Distribution:
Used in bundles or trailers for transport and storage, these cylinders support the safe distribution of hydrogen fuel for industrial, mobility, and energy applications. - Hydrogen Refueling Infrastructure:
Essential for high-capacity refueling stations, especially as the hydrogen economy expands in the transport sector. - Industrial Gas Supply Chains:
Provides specifications that facilitate international trade and secure logistics of compressed hydrogen for factories, laboratories, and power plants. - Sustainable Mobility:
Promotes the use of composite hydrogen cylinders in zero-emission vehicles and public transport, advancing clean energy objectives. - Research and Development:
Sets a technical foundation for innovations in high-pressure hydrogen vessel design, making it valuable for R&D teams focused on next-generation composite materials and safer storage systems.
Related Standards
For comprehensive compliance and best practices, organizations should also consider the following related standards:
- EN 17339:2024 - General requirements for transportable composite gas cylinders and tubes for hydrogen
- ISO 11119 series - Addresses composite cylinder and tube requirements for gases, including hydrogen
- EN ISO 9809-1, EN ISO 9809-2 - Cover requirements for seamless steel gas cylinders that may be used with hydrogen
