Overview

EN 2914:1996 is a CEN aerospace standard that specifies the characteristics for flat, large-diameter washers made of heat-resisting steel and passivated for use in aerospace assemblies. The standard is intended for washers rated for a maximum operating temperature of 650 °C, addressing the needs of high-temperature aerospace environments such as engine and exhaust system components.

Key topics and requirements

While the full text contains the definitive technical clauses, EN 2914 covers the principal areas relevant to high-temperature aerospace washers, including:

  • Material requirements – selection of appropriate heat-resisting steel grades suitable for service up to 650 °C.
  • Surface treatment – specification of passivation methods to improve corrosion resistance and maintain surface integrity in aerospace conditions.
  • Dimensional and geometric characteristics – large-diameter washer form factors suited to load distribution and assembly interfaces (diameters, thickness ranges, and bore sizes are defined in the standard).
  • Mechanical and thermal performance – properties and tests ensuring washers retain function at elevated temperatures.
  • Inspection and testing – requirements for dimensional checks, material verification, surface finish, and possible corrosion or heat exposure tests.
  • Marking, traceability and documentation – provisions for supplier marking, batch traceability and accompanying certification to support aerospace quality systems.

Applications

EN 2914 is focused on practical use in aerospace hardware where high-temperature performance and corrosion resistance are essential. Common applications include:

  • Fastener assemblies in turbine, exhaust, and engine bay components
  • High-temperature joints where load distribution or locking is required
  • Structural and mechanical interfaces exposed to elevated thermal cycles

Using passivated, heat-resisting steel washers helps ensure joint integrity, reduce fretting and corrosion, and maintain clamping performance in demanding thermal environments.

Who should use this standard

  • Aerospace component designers and structural engineers specifying fasteners and washers for high-temperature service
  • Procurement and quality managers sourcing certified aerospace washers
  • Manufacturers and suppliers producing large-diameter, heat-resistant washers
  • Maintenance and repair organizations (MRO) verifying replacement parts and conformity

Related standards

EN 2914 complements other CEN/ISO and aerospace fastener standards that govern washers, bolts, material grades, heat treatment and corrosion protection. When specifying components, cross-reference applicable fastener and material standards to ensure full system compatibility.
