Overview

The European standard oSIST prEN 853:2024:2024 specifies the requirements for wire braid reinforced hydraulic rubber hoses and hose assemblies. It covers four hose types-1SN, 2SN, 1ST, and 2ST-designed for nominal bore sizes ranging from 5 to 76 millimeters. These hoses are engineered for fluid power applications involving hydraulic fluids (per ISO 6743-4), water-based fluids, and water, across specified temperature ranges. This standard updates and supersedes EN 853:2015, reflecting technical enhancements and harmonization with related EN standards.

Key Topics

• Hose Types and Construction

  • Type 1SN and 2SN: Single and double wire braid reinforcements with thinner covers suitable for fittings that do not require cover removal. Recommended for new hydraulic fluid power designs.
  • Type 1ST and 2ST: Single and double wire braid reinforcements with thicker covers; no longer recommended for new hydraulic fluid applications.
  • Hose construction consists of synthetic rubber linings resistant to oil and water, layers of high tensile steel wire reinforcement, and oil/weather-resistant rubber covers with synthetic rubber insulation layers separating wire braids.

• Performance Requirements

  • Hydrostatic pressure thresholds including maximum working, proof, and burst pressures tailored by hose type and nominal bore.
  • Minimum bend radii ensuring hose integrity without significant deformation during operation.
  • Impulse testing at elevated temperatures (100 °C) to simulate dynamic pressure variations in hydraulic systems.
  • Cold flexibility performance down to −40 °C.
  • Resistance to vacuum, ozone, abrasion, and fluid exposure aligned with stringent testing criteria.

• Material Compatibility

  • Suitable for hydraulic fluids (excluding flame retardant HFD R, S, and T types), water-based fluids between −40 °C and +70 °C, and water between 0 °C and +70 °C.
  • Not suitable for castor oil or ester-based fluid applications.

• Dimensions and Tolerances

  • Detailed specifications on hose diameters, concentricity, and length tolerances for both hoses and hose assemblies, conforming to EN ISO 4671.
  • Strict limits on wall thickness variation to ensure consistent hose performance and safety.

Applications

This standard is critical for industries requiring reliable, high-performance hydraulic hose solutions, including:

• Industrial Hydraulic Systems

  • Machinery and manufacturing equipment that operate under high pressure and varying temperatures.

• Mobile Hydraulics

  • Agricultural machinery, construction vehicles, and other off-road equipment relying on fluid power systems.

• Water-Based Fluid Systems

  • Cooling, lubrication, or fluid transport systems using water or water-based hydraulic fluids within specified temperature ranges.

• General Engineering Applications

  • Wherever wire braid reinforced hydraulic hoses are needed to maintain pressure integrity, flexibility, and resistance to environmental stressors.

The standard ensures that hose assemblies produced and installed conform to stringent performance and safety criteria, reducing downtime and failure risk in hydraulic operations.

• EN ISO 6743-4 - Classification of hydraulic fluids suitable for use with hoses under this standard.
• EN ISO 1402 - Procedures for hydrostatic testing of hoses and assemblies.
• EN ISO 4671 - Measurement methods for hose dimensions and assembly lengths.
• EN ISO 6803 - Methods for hydraulic-pressure impulse testing without flexing.
