Overview
FprEN 3155-015 is a CEN draft product standard for female electrical contacts, Type A, crimp, Class S, used in aerospace elements of connection. The document specifies required characteristics, tests and tooling for these contacts and is intended to be used together with EN 3155-001. Associated male contacts are specified in EN 3155-014.
Class S contacts cover an operating temperature range from −65 °C to 200 °C and are intended for general application in aerospace electrical connectors. Body material is specified as a copper alloy with a gold surface treatment and appropriate undercoat in accordance with EN 3155-001.
Key Topics
- Scope and purpose: Defines product requirements, dimensional controls, marking, permissible cables, and tooling for crimp female contacts (Type A).
- Dimensions & mass: Contact geometry, tolerances (in mm) and mass are given in figures and tables; dimensions apply after surface treatment.
- Marking & identification: Colour band coding (per ISO 8843) is used to identify contact sizes and barrels; alternative single-band marking is permitted where applicable.
- Materials & plating: Copper-alloy body with gold plating and specified protective undercoat; selective protection allowed.
- Permissible cables: Acceptable conductor sizes and rated test currents are listed by contact/barrel size (see Table 3 in the standard).
- Tooling: Crimping tools must conform to SAE-AS22520; M22520 series positioners and selectors are referenced, with specific positioner guidance (EN 4008-006 applies for certain positioners).
- Tests & gauges: The standard references the EN 2591 series for test methods (contact resistance, mechanical endurance, environmental tests, tensile strength, insertion/extraction forces, etc.).
Applications
FprEN 3155-015 targets manufacturers, suppliers and systems engineers working on:
- Aerospace connectors and harness assemblies where reliable crimped female contacts are required.
- High-reliability electrical systems that must meet tight dimensional, mechanical and environmental performance criteria.
- Production and quality control processes that need defined tooling, colour coding and test requirements to ensure interchangeability and service performance.
Benefits of compliance include improved interchangeability, documented testability against aerospace test methods, and assurance of performance across the specified temperature range.
