BS EN 2942:1998

Overview

BS EN 2942:1998 specifies the requirements for self-locking helical coil inserts made from heat-resisting nickel base alloy NI-PH2801, commonly known as Inconel X750, which is silver plated. These inserts are designed for use in aircraft and space vehicle engineering applications where high strength and resistance to extreme temperatures are critical.

Key Requirements

The standard outlines the technical specifications and performance criteria necessary for the production and application of these inserts. Key requirements include:

• Material Composition: The inserts must be manufactured from Inconel X750, a nickel-chromium alloy known for its excellent oxidation and corrosion resistance.
• Self-Locking Feature: The design must ensure that the inserts provide a secure locking mechanism, preventing loosening under vibration and thermal cycling.
• Heat Resistance: The inserts must maintain structural integrity at elevated temperatures, making them suitable for high-performance aerospace applications.
• Silver Plating: The silver plating enhances the corrosion resistance and provides a smooth surface finish, facilitating ease of installation.

Implementation Benefits

Utilising BS EN 2942:1998 compliant inserts offers several practical benefits for manufacturers and engineers in the aerospace sector:

• Enhanced Reliability: The self-locking mechanism significantly reduces the risk of component failure due to loosening, which is critical in high-stress environments.
• Improved Performance: The heat-resisting properties of Inconel X750 ensure that the inserts perform reliably under extreme conditions, contributing to the overall safety and performance of the aircraft or spacecraft.
• Cost Efficiency: By reducing maintenance needs and increasing the lifespan of components, these inserts can lead to lower operational costs over time.
• Compatibility: The inserts are designed to be compatible with a variety of materials and can be integrated into existing designs without significant modifications.

Compliance Value

Adhering to BS EN 2942:1998 is essential for compliance with industry regulations and standards. The benefits of compliance include:

• Regulatory Compliance: Meeting the specifications set forth in this standard ensures that products are compliant with international aerospace regulations, which is crucial for certification and safety.
• Market Acceptance: Products that conform to recognised standards are more likely to be accepted in the global market, enhancing business opportunities.
• Quality Assurance: Compliance with this standard demonstrates a commitment to quality and reliability, which can enhance a company's reputation in the aerospace industry.

In conclusion, BS EN 2942:1998 provides critical guidelines for the manufacturing and application of self-locking helical coil inserts in aerospace engineering. By adhering to this standard, manufacturers can ensure the reliability, safety, and performance of their products, ultimately contributing to the advancement of aerospace technology.
