What is EN Standard?
EN Standard refers to a set of European Norms that define safety, quality, and performance requirements for products used across Europe. These standards ensure consistency, reliability, and compatibility between manufacturers and industries.
In the hydraulic hose field, EN standards outline testing, construction, and pressure ratings, helping users select hoses that meet strict European operational expectations and safety rules.
EN Standard Hydraulic Hose Requirements
Understanding EN Standard hydraulic hose requirements helps users ensure their systems meet European expectations for safety, durability, and consistent performance. These standards outline how hoses should be constructed, tested, and labeled, giving engineers and buyers a reliable benchmark when choosing hoses for demanding hydraulic applications across different industries.
EN Standard Hydraulic Hose Requirements
- Pressure Rating Compliance – EN standards outline precise working and burst pressure limits, ensuring every hose can handle continuous loads, sudden spikes, and repetitive system stress, reducing failure risks and helping equipment operate safely and consistently across a wide range of industrial hydraulic applications.
- Material and Construction Rules – These standards define rubber compounds, reinforcement layers, flexibility ranges, and temperature resistance, ensuring hoses stay stable under bending, vibration, abrasion, and exposure to hydraulic fluids, allowing long-term reliability even when used in demanding, fast-paced, or harsh operating environments.
- Testing and Verification Procedures – EN guidelines require strict testing such as impulse cycles, leak checks, dimensional accuracy, and adhesion strength, confirming that hoses perform predictably under real-world pressures and reducing unexpected downtime caused by system failures, maintenance issues, or unpredictable operating conditions.
- Labeling and Traceability – Hoses must display EN codes, pressure ratings, dimensions, and production details, giving technicians quick identification and ensuring replacements are correct, helping maintain compliance, streamline inspections, and support efficient maintenance schedules across various hydraulic systems and equipment setups.
- Compatibility and Fitting Standards – EN rules ensure hoses match safely with European-standard fittings and connectors, preventing leaks, blowouts, and mechanical stress while improving long-term performance, reducing safety risks, and cutting maintenance costs across hydraulic systems operating in both light and heavy industrial settings.

Understanding the difference between EN 853 and EN 857 helps buyers, engineers, and maintenance teams choose the correct hydraulic hose for their systems. Both standards define performance and construction requirements, but they serve different pressure levels, reinforcement designs, and application conditions. Knowing these distinctions prevents mismatches and improves hydraulic reliability.
- Reinforcement Structure – EN 853 hoses usually feature stronger wire reinforcement designed for higher-pressure conditions, while EN 857 hoses use a compact, lighter reinforcement structure. This difference allows EN 853 to handle heavier-duty applications, whereas EN 857 suits tighter spaces and flexible routing in moderate-pressure systems.
- Pressure Rating Range – EN 853 hoses generally support higher working pressures across all sizes, making them suitable for demanding industrial machinery. EN 857 hoses cover lower pressure ranges but still offer reliable performance, making them ideal for medium-duty systems where space, weight, and flexibility matter more than maximum pressure capacity.
- Hose Dimensions and Flexibility – EN 857 hoses are designed to be slimmer and more flexible, enabling easier installation in compact layouts. EN 853 hoses follow a more traditional, thicker hydraulic hose profile, offering durability and strength but requiring more space for routing and bending during system assembly.
- Typical Applications – EN 853 is preferred for construction equipment, mining machinery, and other heavy-pressure hydraulics due to its robust build. EN 857 fits agricultural machines, compact industrial systems, and general-purpose hydraulics where flexibility, maneuverability, and lighter hose designs are more important than extreme pressure capability.
- Temperature and Durability Performance – Both standards perform well under typical hydraulic oil temperatures, but EN 853 hoses are built for more severe duty cycles. EN 857 hoses maintain solid durability but are optimized for space-saving designs rather than extreme, prolonged pressure loads in heavily stressed hydraulic systems.
Here are some differences between EN853 and EN857 hydraulic hoses in the following chart
| Feature | EN 853 | EN 857 |
|---|---|---|
| Reinforcement | Stronger, heavier wire reinforcement | Compact, lighter reinforcement |
| Pressure Rating | Higher pressure capability | Medium pressure capability |
| Flexibility | Less flexible, thicker profile | More flexible, slimmer profile |
| Typical Use | Heavy-duty industrial and mobile machinery | Compact or medium-duty hydraulic systems |
| Durability | Designed for harsh, demanding cycles | Reliable but optimized for tight installation spaces |
Other Hydraulic Hose Testing Standards
Beyond EN standards, several global testing systems help ensure hydraulic hoses meet strict performance and safety expectations. These standards outline how hoses must be evaluated for pressure, impulse cycles, temperature endurance, and long-term durability. Knowing these guidelines helps users compare options and choose hoses that match their hydraulic system requirements.
