What is EN ISO 6806:2014?

EN ISO 6806:2014 is a technical standard that specifies the requirements for rubber hoses and hose assemblies used for aircraft ground fuelling and defuelling. This standard was developed by the International Organization for Standardization (ISO) and is in line with the European Norms (EN). It provides guidelines for manufacturers, suppliers, and users to ensure the quality, safety, and performance of rubber hoses used in aviation fuel transfer operations.

The Scope of EN ISO 6806:2014

This standard covers flexible rubber hoses and hose assemblies designed for aircraft ground fuelling and defuelling. It applies to hoses used for both commercial and military aircraft and includes various types of hoses such as low-pressure hoses, high-pressure hoses, and composite hoses. EN ISO 6806:2014 sets out specific requirements for the construction, performance, and testing of these hoses to ensure they can withstand the challenges of aviation fuel handling and meet the industry's safety standards.

Key Requirements and Testing Procedures

EN ISO 6806:2014 details several key requirements that rubber hoses must meet to comply with the standard. These include dimensional tolerances, resistance to aircraft fuels, flexibility, electrical conductivity, burst pressure, and endurance. The standard also outlines the testing procedures that manufacturers should follow to validate the compliance of their hoses. These tests involve examining the hose's physical properties, its ability to withstand pressure, its resistance to kinking or collapsing, and its exposure to different fuel types and environmental conditions.

Benefits of EN ISO 6806:2014 Compliance

Adhering to EN ISO 6806:2014 brings several benefits to manufacturers, suppliers, and users of rubber hoses in aircraft fuel handling operations. Compliance ensures that the hoses are of high quality, meet safety requirements, and perform reliably in demanding environments. It helps reduce the risk of accidents, such as fuel spills or hose failures, which can have catastrophic consequences. By following this standard, aviation industry stakeholders can have confidence in the hoses they use, ensuring smooth and safe fuel transfer operations on the ground.
