Overview

EN 2591-509:2023 is a European standard developed by CEN that specifies test methods for verifying the adhesion of electrodeposited gold and gold alloy coatings on electrical contacts used in aerospace applications. This standard is part of the aerospace series focused on elements of electrical and optical connections, ensuring high reliability and performance in demanding environments. The 2023 update supersedes the previous 2001 edition, incorporating the latest normative references such as replacing ISO 4524-1 with ISO 27874:2008.

The primary goal of EN 2591-509:2023 is to provide standardized, reproducible test methods for adhesion assessment, reinforcing quality assurance practices in aerospace components where material integrity and dependable electrical contact performance are critical.

Key Topics

• Scope: Defines test procedures to verify the adhesion quality of electrodeposited gold and gold alloy coatings on contacts.
• Test Methods:
  • Method A: Burnishing test method for male contacts sized 4/0 to 16 and socket contacts sized 4/0 to 24, aligned with EN ISO 27874:2008 Annex C.2.
  • Method B: Bending test method for male contacts sized 20 to 24 as per EN ISO 27874:2008 Annex C.5.
• Visual Examination: Inspect coatings under magnification (×8 or ×4 under illumination) unless otherwise specified.
• Normative References: Includes EN 2591-100 for general test methods and EN ISO 27874:2008 for specifications related to electrodeposited gold coatings.
• Terminology: Utilizes terms defined in EN 2591-100 and international databases such as ISO Online Browsing Platform and IEC Electropedia.

Applications

EN 2591-509:2023 is essential for aerospace manufacturers, quality control engineers, and certification bodies involved in the production and validation of electrical and optical connectors. Ensuring the adhesion of gold coatings on contact surfaces is vital to:

• Enhance corrosion resistance and electrical conductivity in aerospace connectors.
• Maintain mechanical stability and long-term durability under environmental stress.
• Prevent contact failure caused by coating degradation in harsh operational conditions.
• Compliance with aerospace industry standards for safety, performance, and reliability.

It enables aerospace suppliers and manufacturers to validate coating processes, safeguard connector integrity, and meet international regulatory requirements, ultimately supporting mission-critical aerospace systems.
