Overview

kSIST FprEN 856:2026 is the European Standard developed by CEN (European Committee for Standardization) that specifies performance requirements for four types of rubber-covered, spiral wire reinforced hydraulic hoses and hose assemblies. Covering nominal bores from 6 to 51, it includes Types 4SP, 4SH, R13, and R15, which are widely used in demanding hydraulic applications.

This standard defines the dimensional, mechanical, and performance characteristics for hoses intended for use with hydraulic fluids (except certain flame retardants and non-approved oils) and water-based fluids within set temperature ranges. Critical for manufacturers and users, kSIST FprEN 856:2026 updates and aligns content with related hose standards, ensuring compatibility and safety in fluid power systems.

Key Topics

• Hose Types Covered:

  • Type 4SP: Four steel wire spiral, medium pressure hose
  • Type 4SH: Four steel wire spiral, extra high pressure hose
  • Type R13/R15: Multiple steel wire spirals, heavy-duty and high temperature hoses

• Compatibility:

  • Suitable for use with hydraulic fluids in accordance with ISO 6743-4, excluding all flame retardant HFD types
  • Usable with water-based fluids up to 70°C, and with hydraulic fluids at temperatures ranging from −40°C to +100°C (4SP, 4SH) or up to +120°C (R13, R15)
  • Not suitable for castor oil or ester-based fluids

• Performance Requirements:

  • Minimum hydrostatic, burst, and proof pressures
  • Tests for flexibility, leak resistance, impulse resistance, abrasion, fluid compatibility, and ozone resistance
  • Specified dimensional tolerances and concentricity

• Marking and Labelling:

  • Requirements for product identification, pressure rating, type, bore size, and manufacturing date

Applications

kSIST FprEN 856:2026 spiral wire reinforced rubber hydraulic hoses are used extensively in:

• Heavy equipment and machinery: Excavators, loaders, cranes, and construction vehicles, where high pressure hydraulic systems are crucial
• Industrial hydraulic systems: Presses, injection molding, and material handling machinery, requiring robust and reliable hose assemblies
• Transportation equipment: Trucks, agricultural machinery, and forestry machines that operate in diverse climates
• Hydraulic circuit maintenance and OEM kit production: For system repairs and new installations where adherence to international standards is required

By following kSIST FprEN 856:2026, manufacturers and users can ensure hydraulic hose assemblies deliver consistent performance, withstand severe operating conditions, and maintain safety over long service periods.

Related Standards

kSIST FprEN 856:2026 is designed to integrate with other key hydraulic hose and testing standards, including:

• EN ISO 1402: Hydrostatic testing for hoses and hose assemblies
• EN ISO 4671: Measurement of hose and assembly dimensions
• EN ISO 6803: Hydraulic-pressure impulse testing
• EN ISO 8033: Adhesion testing between hose components
• EN ISO 7326: Ozone resistance testing
• EN ISO 10619-2: Flexibility testing at low temperatures
• ISO 1817: Fluid resistance testing of rubber and thermoplastic materials

Related product standards:

• EN 853: Rubber hoses and assemblies – wire braid reinforced
• EN 857: Rubber hoses and assemblies – compact wire braid

With kSIST FprEN 856:2026, industry professionals benefit from improved interoperability, enhanced safety, and reliable hydraulic performance by applying internationally harmonized quality and compliance criteria. This standard is essential for procurement, manufacturing, and maintenance in sectors where hydraulic hose performance directly impacts productivity and safety.
