Overview

EN 3155-081:2019 is a CEN product standard in the aerospace series that defines required characteristics and qualification tests for electrical female contacts size 22, type A, crimp, class T used in elements of connection (per EN 3155-002). Published in 2019, this document is intended to be used together with EN 3155-001 (technical specification) and references the associated male contacts defined in EN 3155-080. It applies to aerospace applications where reliable, high-temperature-capable crimp contacts are required.

Key topics and requirements

• Contact type and class: Female, Type A, crimp termination, Class T (operating temperature range −65 °C to 260 °C).
• Dimensions and mass: Detailed dimensional drawings and tolerances (in mm) are specified; maximum mass 0.20 g.
• Identification and marking: Colour-code bands per ISO 8843 (green/white for size 22) and designation format (e.g. CONTACT, ELECTRICAL EN3155-081F2222).
• Materials and finishes: Copper alloy body with gold plating on an appropriate undercoat; coating thickness recorded and minimums required on active areas (initial and after test).
• Permissible cables and crimping: Allowed conductor sizes and AWG equivalents are listed; crimp tooling conforms to SAE‑AS22520 (M22520/2 series) and insertion/extraction tools to SAE‑AS81969.
• Cable preparation: Specified stripping length (4.5 mm ±0.5 mm for size 22).
• Qualification and tests: Comprehensive test program referencing the EN 2591 test methods, including:
  • Contact resistance (low level and at rated current), insulation resistance, voltage proof
  • Environmental endurance: high-temperature cycling (260 °C), rapid temperature changes, salt mist, fluid and ozone resistance
  • Mechanical: shock, vibration, mechanical endurance, gauge insertion/extraction forces, tensile and bending strength
  • Plating and solderability checks, restricted entry, probe damage, and coating thickness measurement

Applications and users

Who uses EN 3155-081:2019:

• Aerospace connector manufacturers specifying and producing size 22 female crimp contacts
• Design and systems engineers integrating circular connectors compliant with EN 2997
• Quality, test and certification laboratories performing EN 2591 test sequences
• Maintenance, procurement and avionics specialists ensuring component interchangeability and traceability

Practical uses:

• Selection and procurement of crimp contacts for aircraft wiring harnesses operating in high-temperature environments
• Defining manufacturing, inspection and qualification criteria for contact production and crimp processes
• Ensuring compatibility with mating male contacts (EN 3155-080) and connector shells compliant with EN 2997

Related standards
