EN 2424:2008

Overview

EN 2424:2008 is a European standard developed by CEN, specifying the rules for marking aerospace products. It applies to all aerospace products when referenced in their definition documents. The standard ensures consistent identification of aerospace parts, supporting traceability, quality control, and regulatory compliance throughout the aerospace industry.

This marking protocol is essential for identifying both the product and its manufacturer, relying on clear, permanent markings that meet predefined style and legibility requirements. EN 2424:2008 supersedes the earlier 1995 version and aims to harmonize marking practices across CEN member countries, including Austria, Germany, France, UK, and many others.

Key Topics

• Scope and Application
  EN 2424:2008 defines marking requirements used whenever referenced by a product’s definition document, primarily focusing on aerospace components.

• Manufacturer Identification
  Marking includes the manufacturer’s monogram or name, registered with ASD-STAN, ensuring clear traceability.

• Marking Styles
  The standard describes several marking styles (A to P), ranked by preference:

  • Style A: Full identification including product identity block and manufacturer monogram (preferred).
  • Styles B, C, D, etc.: Alternative markings used when space or product characteristics limit Style A.
  • Special provisions exist for threaded products and packaging labels.

• Marking Practices

  • Positioning must avoid impairment to product function and allow identification in assembled conditions.
  • Markings must be permanent, made by indention or embossing within specified depth limits (0.05 mm to 0.25 mm).
  • Legibility is mandatory without magnification, with preferred character height 1.5 mm; smaller sizes allowed only under restricted conditions.

• Product Identification Priority
  Where space allows, the EN part number takes precedence over manufacturer part numbers.

Applications

• Aerospace Manufacturing
  Facilitates the accurate identification and traceability of aerospace components for manufacturers and suppliers.

• Quality Assurance and Compliance
  Enables regulatory bodies and quality inspectors to verify the origin and conformity of aerospace parts during production and maintenance.

• Supply Chain Management
  Standardized markings help streamline logistics, inventory management, and inspection processes across the aerospace supply chain.

• Maintenance and Repairs
  Markings ensure replacement parts are correctly identified, improving safety and reliability in aerospace operations.
