EN 2004-1:1993

Overview

EN 2004-1:1993 is a CEN aerospace-series standard that specifies a non-destructive test method for determining the electrical conductivity of wrought aluminium alloys. The standard is intended for use when it is referenced in procurement, inspection or certification documents. The same text has been adopted nationally as SIST EN 2004-1:2001.

Key topics

• Scope: Defines the applicability to wrought aluminium and aluminium alloys used in aerospace applications.
• Test type: Specifies a non-destructive procedure to determine electrical conductivity (no material removal or destructive sampling required).
• Measurement purpose: Provides a repeatable way to verify electrical conductivity as a material property for quality control and conformity assessment.
• Reference and applicability: Intended to be applied where explicitly referenced in contracts, specifications or regulatory documents.
• Documentation: Requires appropriate recording of test conditions and results to support traceability and acceptance decisions.

(Note: the standard text itself should be consulted for exact procedural steps, calibration, environmental conditions and reporting requirements.)

Applications

EN 2004-1:1993 is practical for:

• Aerospace manufacturers and suppliers verifying incoming wrought aluminium billets, plates or extrusions.
• Quality assurance and inspection teams performing acceptance tests without damaging parts.
• Maintenance, repair and overhaul (MRO) organizations checking in-service components for property changes.
• Materials laboratories conducting routine screening and conformity checks.
• Procurement and certification where contractual specifications reference electrical conductivity limits.

Key practical benefits include rapid, repeatable verification of material condition, support for process control, and non-destructive assessment during production and in-service inspection.

Who uses this standard

• Aerospace OEMs and tiered suppliers
• Metallurgists and materials engineers
• NDT/inspection professionals and laboratory personnel
• Regulatory bodies and certification authorities involved in aerospace materials
