Understanding the China EN856 4SH Standard A Comprehensive Overview

In the world of hydraulic systems, ensuring compatibility and performance is crucial for achieving optimal results. One significant standard that addresses these requirements is the China EN856 4SH standard. This standard primarily pertains to hydraulic hoses, which are essential components in various industrial applications, including construction, mining, and agriculture. This article delves into the specifications, benefits, and applications of hoses manufactured under the China EN856 4SH standard.

What is the EN856 4SH Standard?

The EN856 4SH standard is a European norm that specifies the performance requirements for high-pressure hydraulic hoses. The 4SH designation indicates a four-layer steel wire braid reinforcement that provides exceptional strength and durability, making these hoses suitable for high-pressure applications. The standard outlines criteria for the hoses' physical properties, including their ability to withstand pressure, temperature, and various environmental conditions.

Key Specifications

1. Construction Hoses conforming to the EN856 4SH standard are manufactured with a synthetic rubber inner tube, which is designed to handle a range of hydraulic liquids. The four layers of steel wire braiding reinforce the hose, allowing it to endure high-pressure conditions without bursting or failing.

2. Pressure Ratings Depending on the size of the hose, the EN856 4SH standard typically supports operating pressures of up to 420 bar (6,090 psi). This high pressure makes it suitable for demanding applications requiring robust hydraulic performance.

3. Temperature Range These hoses are usually rated for temperatures ranging from -40°C to +100°C (-40°F to +212°F), with some variations depending on the specific rubber compounds used in manufacturing. This wide temperature range ensures that the hoses can function effectively in various working environments.

4. Compatibility The hoses are compatible with a variety of hydraulic fluids, including mineral oils, water-glycol solutions, and biodegradable fluids. This versatility allows for their application across different industries and applications.
