Overview

EN 3155-079:2019 is a CEN product standard in the aerospace series that specifies required characteristics and tests for female electrical contacts size 22, Type A, crimp, class S used in elements of connection according to EN 3155-002. It is intended to be used together with EN 3155-001 (technical specification) and pairs with the associated male contacts defined in EN 3155-078. The standard targets aerospace electrical contacts designed for continuous operation from −65 °C to 200 °C (class S).

Key topics and technical requirements

• Contact type and class
  • Female, size 22, Type A, crimp termination, class S (temperature range −65 °C to 200 °C).
• Materials and plating
  • Body material: copper alloy.
  • Surface treatment: gold over an appropriate undercoat; thickness and selective protection per EN 3155-001.
• Dimensions and mass
  • Detailed dimensional drawings and tolerances (mm); maximum mass 0.20 g after surface treatment.
• Marking and identification
  • Colour bands per ISO 8843 (size 22: green/green; single band allowed if both bands are same color).
• Permissible cables and crimping
  • AWG and conductor sizes referenced to EN 2083 / EN 4434; crimping tools specified to SAE‑AS22520 (M22520 variants); insertion/extraction tools per SAE‑AS81969.
• Test program
  • Comprehensive tests referenced to EN 2591 series and EN 3155-001 including: low-level contact resistance, rated-current resistance, insulation resistance, voltage proof, overload, endurance at 200 °C for 1 000 h, thermal cycling, shock, vibration, mechanical endurance, crimp tensile strength, restricted entry and plating/coating inspections.
• Assembly and test configuration
  • Contacts tested in EN 2997 connectors with harnessing, heat-shrink boot and lacing per specified test arrangements.

Applications and users

• Who uses this standard
  • Aerospace connector manufacturers, cable harness suppliers, design engineers, qualification and test laboratories, procurement and quality assurance teams.
• Typical applications
  • Circular electrical connectors (EN 2997 family) in aircraft and aerospace systems requiring high-reliability crimp contacts for harsh environments, elevated temperatures, vibration and shock.
• Practical value
  • Ensures interchangeability, reliable crimp joints, repeatable test methods and traceable marking for safety‑critical aerospace wiring.

Related standards

• EN 3155-001 (technical specification)
• EN 3155-002 (contact list & utilization)
• EN 3155-078 (male contacts, size 22)
• EN 2997 (circular connectors)
• EN 2591 (test methods), EN 2083, EN 4434, ISO 8843, SAE‑AS22520, SAE‑AS81969
