SIST EN 3475-201:2004

Overview

SIST EN 3475-201:2004 is a European standard developed by the European Association of Aerospace Manufacturers (AECMA) under the CEN framework. It specifies the test method for visual examination of electrical conductors and cables intended for aircraft use. This standard is part of the aerospace series addressing electrical cable quality and consistency, ensuring safety and reliability in aviation.

The standard is designed to be used in conjunction with EN 3475-100, which lays out the general requirements for aerospace electrical cable testing. SIST EN 3475-201:2004 focuses exclusively on the visual inspection process, providing essential guidelines to identify surface defects and ensure conformity to quality standards.

Key Topics

• Scope and Purpose
  Defines the method for visual inspection of conductors and cables used in aerospace electrical systems.

• Conductors Examination
  Conductors must have a smooth and regular appearance free from visible abnormalities.

• Cable Examination
  Cables should:

  • Show no visible defects such as cracks, dents, or irregularities.
  • Have a smooth surface texture without abrasions.
  • Be correctly marked according to the relevant product standard for identification and traceability.

• Inspection Methods
  Visual examination must be performed by:

  • The naked eye with normal vision.
  • Optional use of appropriate optical aids if specified to enhance defect detection.

• Normative References
  Uses EN 3475-100 as a foundational document for general test method principles applicable to other parts of aerospace cable testing.

Applications

SIST EN 3475-201:2004 is fundamental for aerospace manufacturers, maintenance organizations, and quality control personnel involved in:

• Aircraft electrical cable manufacturing
  Ensures produced cables meet stringent aerospace standards for electrical safety and performance.

• Quality assurance in component inspection
  Enables early detection of visual defects that could compromise cable integrity or reliability.

• Maintenance and repair of aircraft wiring systems
  Helps in systematic inspection protocols required during routine servicing to uphold operational safety.

• Certification and compliance
  Supports meeting regulatory requirements by standardizing visual inspection procedures across European aerospace industries.

Related Standards

For comprehensive testing and certification of aerospace electrical cables, SIST EN 3475-201:2004 refers to and should be used alongside:

• EN 3475-100 – Aerospace series cables, general test methods, providing overarching testing frameworks applicable to all cable parts.

• Other parts of the EN 3475 series detailing specific tests like electrical, mechanical, and environmental performance assessments.

These related documents collectively ensure the reliability and safety of aircraft electrical wiring systems by standardizing material quality and testing practices throughout Europe.
