Overview

kSIST FprEN 857:2026 is a European standard developed by CEN that specifies requirements for rubber hoses and hose assemblies reinforced with wire braid, specifically the compact types 1SC and 2SC. The standard covers hoses with a nominal bore from 6 mm to 76 mm, designed for use in hydraulic applications. These hoses are suitable for a range of fluids and operating temperatures, and are widely used in hydraulic systems for their compact dimensions and robust mechanical properties.

kSIST FprEN 857:2026 applies to hoses and assemblies intended for:

• Hydraulic fluids in compliance with ISO 6743-4 (excluding all flame retardant HFD fluids), with operating temperatures from −40 °C to +100 °C
• Water-based fluids at −40 °C to +70 °C
• Water at 0 °C to +70 °C

This standard is focused on hose performance and construction and does not prescribe requirements for specific end fittings. It does not apply to hydraulic hoses intended for underground mining.

Key Topics

Types of Hoses:

• Type 1SC: Single wire braid reinforced compact hose
• Type 2SC: Double wire braid reinforced compact hose

Materials & Construction:

• Oil and water-resistant synthetic rubber lining
• Steel wire braid reinforcements (one or two layers)
• Weather-resistant rubber outer cover

Performance Requirements:

• Maximum working pressures, proof pressures, and burst pressures specified for each type and size
• Minimum bend radius to maintain flexibility
• Resistance to abrasion, vacuum, ozone, fluids, and cold temperatures
• Adhesion between hose components

Testing & Quality Assurance:

• Hydrostatic pressure testing
• Dimensional checks for inside diameter, outside diameter, and concentricity
• Routine and type testing for product qualification and production consistency
• Marking requirements for easy identification and traceability, including manufacturer, hose type, size, and pressure rating

Applications

kSIST FprEN 857:2026 hoses and hose assemblies offer practical value in a wide range of hydraulic applications, including:

• Industrial hydraulic systems
• Mobile machinery (e.g., excavators, cranes, agricultural equipment)
• Construction and mining equipment (excluding underground mining)
• Maintenance and replacement in existing hydraulic circuits requiring compact hoses

Their compact design makes them ideal where installation space is limited, and the robust wire braid reinforcement offers high pressure capability, flexibility, and longevity even in challenging environments.

Key considerations for application include:

• Compatibility with fluids as specified (avoid castor oil-based and phosphoric ester-based fluids)
• Temperature limitations based on fluid type
• Performance verification according to the standard's test requirements for reliable and safe hydraulic operation

Related Standards

kSIST FprEN 857:2026 references and aligns with several international standards to ensure reliability and consistency in hydraulic hose performance, including:

• ISO 6743-4: Hydraulic fluid specification
• EN ISO 1402: Hydrostatic testing methods for hoses and hose assemblies
• EN ISO 4671: Dimensional measurement of hoses and assemblies
• EN ISO 6803: Impulse testing for pressure hoses
• EN ISO 7233: Vacuum resistance determination
• EN ISO 8033: Adhesion testing between hose components
• EN ISO 10619-2: Flexibility and stiffness testing at sub-ambient temperatures
• ISO 1817: Fluid resistance testing methods
• ISO/TS 20444: Abrasion resistance testing
• EN ISO 7326: Ozone resistance testing

Other standards may apply depending on specific applications or additional requirements, particularly in specialized sectors such as underground mining.

kSIST FprEN 857:2026 is an essential specification for ensuring the safety, reliability, and durability of wire braid reinforced compact hydraulic hoses and assemblies in diverse industrial settings.
