The DIN EN 853 standard is a European specification for wire-braided, reinforced rubber hoses and hose assemblies used in hydraulic applications. It defines the performance requirements for hoses that convey various hydraulic fluids under pressure, differentiating between types like EN 853 1SN (single steel wire braid) and EN 853 2SN (double steel wire braid), which align with SAE 100R1 and SAE 100R2 respectively.
Key Aspects of the DIN EN 853 Standard
Scope:
This standard specifies requirements for rubber hoses and hose assemblies with wire braid reinforcement, intended for hydraulic systems.
Hydraulic Fluid Compatibility:
The hoses are designed to carry various hydraulic fluids, including petroleum-based and water-based fluids, such as mineral oils, glycol, polyglycols, and oil emulsions.
Reinforcement:
Hoses are reinforced with high-tensile steel wire braids to withstand high pressures.
Hose Types:
EN 853 1SN: Features a single steel wire braid, equivalent to the SAE 100R1 standard.

EN 853 2SN: Uses a double steel wire braid, aligning with the SAE 100R2 standard.

 
Cover:
The outer cover is made from heat, abrasion, and ozone-resistant synthetic rubber.
Performance Requirements:
The standard focuses on the performance of the hoses and assemblies, rather than on fittings.
Common Applications:
DIN EN 853 hoses are widely used in industries such as: Oilfield and mining, Agricultural machinery, and Construction equipment.
