Overview
EN 3475-203:2006 is a CEN/AECMA aerospace test-method standard for measuring the dimensions of electrical conductors and cables used in aircraft. Intended to be used together with EN 3475-100 (General), this part defines the apparatus, measurement procedures and acceptance requirements for conductor diameter, insulation/jacket thickness and external diameter. Keywords: EN 3475-203, aerospace cables, cable dimensions, test methods, conductor diameter.
Key topics and requirements
Scope
- Specifies a method for measuring dimensions of conductors and cables for aircraft use.
- To be applied in conjunction with EN 3475-100.
Required apparatus
- Friction or dial micrometer with flat ends (≥5 mm for conductors/single cables; ≥15 mm for multiconductor cables).
- Vernier capability to 0.01 mm.
- Profile projector or measuring microscope for insulation/jacket profiles.
Conductor measurements
- Verify number of strands and nominal strand diameter.
- Measure straightened conductor outside diameter (OD) at a minimum of three locations ~1 m apart.
- Each location: two micrometer readings at 90° to each other; report the average OD.
Insulation and jacket
- Distinguishes wrapped vs. extruded constructions:
- Wrapped: verify number of tapes, tape sealing/overlap and minimum outer layer thickness.
- Extruded: measure radial thickness at thinnest and thickest points.
- Minimum average thickness: take four successive measurements around circumference at 90° intervals, starting at the thinnest point.
- Distinguishes wrapped vs. extruded constructions:
External diameter (OD)
- Single insulated wire/cable: measure OD in at least three locations ~1 m apart, two readings at 90° each.
- Non-cylindrical cables: measure at least six equidistant locations, measuring at maximal overall dimension.
- OD reported as average over insulation/jacket.
Acceptance criteria
- Measured strand/count/diameter and conductor OD must conform to the applicable product standard or technical specification.
- For extruded jackets, minimum radial thickness must be ≥70% of maximum measured thickness.
- Average of four thickness measurements must meet product-standard minimums.
Applications and users
- Practical for aerospace manufacturers, cable designers, quality assurance/inspection teams, test laboratories, and certification bodies involved in aircraft wiring.
- Used during incoming inspection, production control, qualification testing and compliance verification to ensure cable geometry meets product specifications and airworthiness requirements.
- Keywords: aircraft cable testing, insulation thickness, micrometer measurement, aerospace wiring standards.
Related standards
- EN 3475-100 (Aerospace series - Cables, electrical, aircraft use - Test methods - Part 100: General) - mandatory companion document.
- EN 3475 series (other parts) and product-specific cable standards referenced for acceptance criteria.
