BS EN 2949:1997

Overview

BS EN 2949:1997 specifies the requirements for wire locking washers made from corrosion resisting steel and passivated to enhance their durability and performance in aerospace applications. These washers are critical components in the assembly of aircraft and space vehicles, providing reliable locking mechanisms that prevent loosening due to vibration and dynamic loads.

Key Requirements

The standard outlines several key specifications that must be adhered to when manufacturing and using wire locking washers:

• Material Composition: Washers must be made from corrosion resisting steel, ensuring longevity and resistance to environmental factors.
• Passivation Treatment: The washers must undergo passivation to improve corrosion resistance, which is essential for components exposed to harsh conditions.
• Dimensional Tolerances: The standard provides specific dimensional tolerances to ensure compatibility and functionality within assembly systems.
• Mechanical Properties: Washers must meet defined mechanical properties to ensure they can withstand the operational stresses encountered in aerospace applications.

Implementation Benefits

Adhering to BS EN 2949:1997 provides several practical benefits for manufacturers and compliance professionals:

• Enhanced Safety: Using compliant wire locking washers reduces the risk of component failure, which can lead to catastrophic failures in aircraft and space vehicles.
• Improved Reliability: The corrosion resistance and mechanical integrity of these washers ensure that assemblies remain secure over time, even in challenging environments.
• Standardisation: Compliance with this standard facilitates uniformity in manufacturing processes, leading to easier integration of components across different systems.
• Quality Assurance: Following the specifications of BS EN 2949:1997 aids in maintaining high-quality production standards, which is critical in the aerospace sector.

Compliance Value

Compliance with BS EN 2949:1997 is not just a regulatory requirement; it is a commitment to quality and safety in aerospace engineering. By ensuring that wire locking washers meet the specifications outlined in this standard, manufacturers can:

• Meet Regulatory Standards: Compliance with this standard is often a prerequisite for certification by aviation authorities, ensuring that products can be used in commercial and military applications.
• Enhance Market Competitiveness: Adhering to recognised standards can improve a company's reputation and increase its competitiveness in the aerospace market.
• Facilitate International Trade: Compliance with European standards can ease the process of exporting products to other countries, as it demonstrates adherence to internationally recognised quality benchmarks.

In conclusion, BS EN 2949:1997 is a vital standard for ensuring the reliability and safety of wire locking washers in aerospace applications. By following its guidelines, manufacturers can enhance product quality, ensure compliance with regulatory requirements, and contribute to the overall safety of aircraft and space vehicles.
