EN 2070-5:1989

Overview

EN 2070-5:1989 is a European standard developed by CEN that specifies technical requirements for aluminium and aluminium alloy wrought products in the aerospace sector. Part 5 of this aerospace series focuses explicitly on tubes used under pressure, commonly manufactured through extrusion or combined extrusion and drawing processes. The standard defines the characteristics and testing criteria to ensure the reliability and safety of round-section aluminium tubes when subjected to pressure, playing a critical role in aerospace applications where material performance is paramount.

This standard is intended to be used in conjunction with EN 2070-1, which provides general specifications for wrought aluminium products in aerospace, thereby ensuring a comprehensive approach to material quality assurance.

Key Topics

• Material Scope: Covers tubes of round cross-section made from aluminium and its alloys suitable for pressurized aerospace systems.
• Manufacturing Methods: Specifies tubes manufactured by extrusion or by extrusion followed by drawing to achieve precise dimensions and mechanical properties.
• Pressure Application: Sets requirements for tubes designed specifically to withstand internal pressure safely in operating environments typical to the aerospace industry.
• Technical Specifications: Includes mechanical properties, dimensional tolerances, surface quality, and testing protocols to verify product compliance.
• Quality Assurance: Highlights the importance of process control, inspection, and documentation aligned with aerospace industry standards.
• Reference to EN 2070-1: Emphasizes that EN 2070-5 is to be applied alongside EN 2070-1 to cover all relevant supply and performance aspects.

Applications

The EN 2070-5:1989 standard finds broad use in aerospace manufacturing and maintenance operations, particularly in areas requiring:

• Aircraft Hydraulic Systems: Pressure tubes transporting fluids under high pressure.
• Pneumatic Systems: Tubing supplying compressed gases safely within aerospace vehicles.
• Fuel and Coolant Lines: Tubes designed to contain pressurized fuels or cooling agents reliably.
• Structural Components: Tubes integrated into pressurized compartments or assemblies requiring strict adherence to material performance.
• Spacecraft Systems: Lightweight, durable pressurized tubing essential for spacecraft fluid management.

By adhering to EN 2070-5, manufacturers and engineers ensure that aluminium tubing used under pressure meets stringent aerospace safety and performance criteria, thereby minimizing risk and enhancing system integrity.
