Overview

SIST EN 2998:2001 is a European standard published by CEN that defines the specifications for flat washers made from heat resisting steel, which are passivated for enhanced durability. These washers are designed specifically for aerospace applications where components are exposed to elevated temperatures. The standard ensures that washers can operate effectively at a maximum temperature of 650 °C, maintaining structural integrity and corrosion resistance under demanding aerospace conditions.

This standard plays a critical role in ensuring the reliability and safety of fastening solutions used in aerospace engineering, where materials must withstand thermal stresses without compromising performance.

Key Topics

  • Material Specifications: Defines the use of heat resisting steel to ensure washers can tolerate high temperatures up to 650 °C without degradation.
  • Surface Treatment: Specifies passivation processes to enhance corrosion resistance and extend service life.
  • Dimensional Requirements: Standardizes dimensions to ensure interchangeability and compatibility with aerospace fasteners.
  • Thermal Performance: Ensures washers maintain mechanical properties and dimensional stability under thermal cycling in aerospace environments.
  • Quality and Testing: Establishes inspection criteria and testing methods for material composition, mechanical strength, and surface characteristics.

Applications

SIST EN 2998:2001 washers are critical components in various aerospace engineering applications, including:

  • Aircraft engine assemblies where components are exposed to high operating temperatures.
  • Structural airframe connections requiring reliable fastening with resistance to thermal expansion and corrosion.
  • High-temperature sealing and vibration damping in aerospace mechanical systems.
  • Any aerospace part that demands durable flat washers capable of maintaining mechanical integrity at elevated temperatures up to 650 °C.

By adhering to this standard, aerospace manufacturers can ensure product quality, safety, and compliance with international requirements, minimizing risks related to component failure in extreme environments.
