Overview

kSIST FprEN 853:2026 is a European standard developed by CEN that specifies the requirements for wire braid reinforced rubber hoses and hose assemblies used in hydraulic fluid power systems. The standard applies to four distinct types of hoses-1SN, 2SN, 1ST, and 2ST-with nominal bores ranging from 5 mm to 76 mm. This guideline covers hoses suitable for use with a wide range of hydraulic fluids (excluding flame retardant HFD types), water-based fluids, and water within specific temperature limits.

kSIST FprEN 853:2026 is highly relevant for manufacturers, suppliers, and users of hydraulic equipment in industrial, construction, and machinery applications, ensuring consistent quality, performance, and safety.

Key Topics

• Types and Construction:
  • Four hose types: 1SN and 2SN (thinner covers for newer fittings), 1ST and 2ST (traditional types).
  • Reinforcement with one or two braids of high tensile steel wire.
  • Oil and water resistant synthetic rubber lining and cover.
• Dimensional Requirements:
  • Detailed specifications for internal diameters, cover thickness, and concentricity.
  • Tolerances for overall hose and assembly length.
• Performance Criteria:
  • Maximum working pressure, proof pressure, and burst pressure values across the full size range.
  • Requirements for minimum bend radius and cold flexibility (down to -40°C).
  • Testing for hydrostatic performance, impulse cycles, leakage, and vacuum resistance.
  • Fluid resistance (oil, water, water-glycol), abrasion, and ozone resistance tests to ensure product longevity and reliability.
• Marking and Identification:
  • Clear marking requirements for both hoses and hose assemblies, including manufacturer identification, type, bore, pressure rating, and date code.

Applications

kSIST FprEN 853:2026 wire braid reinforced hydraulic hoses and assemblies are widely used in:

• Hydraulic Fluid Power Systems: For machinery, industrial equipment, mobile hydraulics, and agricultural machinery, where reliability and safety are critical.
• Construction Equipment: Excavators, cranes, loaders, and mobile platforms benefit from robust and flexible hydraulic hoses that meet EN 853 requirements.
• Manufacturing and Industrial Plants: Hydraulic hoses conforming to EN 853 are essential in automated processes, presses, and robotics.
• Maintenance and Replacement: Standardized hose assemblies simplify replacement processes, minimize downtime, and enhance compatibility across various brands and equipment.

These hoses are designed for operation with a broad range of hydraulic fluids (excluding castor oil and ester-based fluids) under significant pressure and harsh environmental conditions, extending equipment longevity and maintaining operational safety.

Related Standards

Several related standards provide further guidance and compatibility for hydraulic hoses and assemblies, including:

• EN ISO 1402: Hydrostatic testing for hoses and hose assemblies.
• EN ISO 4671: Methods of measuring dimensions and lengths of hoses and assemblies.
• EN ISO 6803: Hydraulic-pressure impulse test without flexing.
• EN ISO 7326: Assessment of ozone resistance under static conditions.
• EN ISO 8033: Determination of adhesion between hose components.
• EN ISO 10619-2: Flexibility and stiffness tests at sub-ambient temperatures.
• ISO 1817: Determination of the effect of liquids on rubber.
• ISO/TS 20444: Abrasion resistance of hose outer cover.
• EN 857: Specifies hoses for higher-pressure hydraulic applications with different construction (wire braid reinforcement).

kSIST FprEN 853:2026 supersedes EN 853:2015, incorporating updated references and harmonized requirements with other hydraulic hose standards, supporting safe, reliable, and standardized hydraulic hose solutions throughout Europe and internationally.
