What is EN ISO 3862:2014?

EN ISO 3862:2014 is a technical standard that specifies the requirements for rubber hoses and hose assemblies that are used in hydraulic systems. This standard was developed by the European Committee for Standardization (CEN) and is recognized internationally.

The Importance of EN ISO 3862:2014

This standard plays a crucial role in ensuring the safety and reliability of hydraulic systems. Hydraulic hoses are used to transmit fluid power within a hydraulic system, and any failure or defect in these hoses can lead to serious accidents or equipment damage. The purpose of EN ISO 3862:2014 is to establish the requirements for hydraulic hoses and hose assemblies, including their construction, performance, and testing.

Key Requirements of EN ISO 3862:2014

EN ISO 3862:2014 outlines several key requirements that hydraulic hoses must meet. These include specifications for their inner tube, reinforcement, cover, and fluid compatibility. For example, the inner tube of the hose should be resistant to the type of fluid being conveyed, as well as the temperature and pressure conditions it will be subjected to. The reinforcement layers should provide sufficient strength and flexibility, while the outer cover should protect the hose from environmental factors such as abrasion, ozone, and sunlight.

Testing and Certification

In order to ensure compliance with EN ISO 3862:2014, hydraulic hose manufacturers must subject their products to various tests. These tests evaluate the durability, performance, and safety of the hoses under different conditions. Some of the commonly conducted tests include burst pressure test, impulse test, flexing test, and leakage test. Manufacturers who successfully meet the requirements of this standard can obtain certification, which demonstrates their product's compliance and quality.
