EN 2076-3:1989

Overview

EN 2076-3:1989 (Aerospace series) defines the particular requirements for aluminium and magnesium alloy pre-production and production castings when the material complies with EN 2076-2. Published by CEN for aerospace applications, this part focuses on castings used in qualification and series manufacture. EN 2076-3 is intended to be used together with EN 2076-1 to provide a complete technical specification for alloy ingots and castings.

Key Topics

This part of the EN 2076 series addresses the specific requirements relevant to casting supply, manufacture and inspection. Key topics include:

• Scope and applicability for pre-production (qualification) and production castings in aluminium and magnesium alloys.
• Requirements linked to EN 2076-2: castings must be produced from material that meets the compositional and general material provisions of EN 2076-2.
• Qualification of manufacturing methods: application to pre-production castings used to qualify the casting process and inspection regimes before series production.
• Inspection and acceptance: provisions for inspection activities and criteria to confirm conformity of castings to the agreed specification.
• Documentation and traceability: requirements for records that demonstrate material provenance and manufacturing/inspection history (as typical in aerospace specifications).
• Relationship to general technical requirements: how Part 3 complements the broader requirements given in EN 2076-1.

(Note: EN 2076-3 specifies particular requirements; for full technical procedures, tolerances and testing details refer to the standard text and the related Parts 1 and 2.)

Applications

EN 2076-3 is practical for organizations and professionals involved in aerospace casting supply chains:

• Foundries and casting manufacturers producing aluminium and magnesium aerospace components.
• Quality and materials engineers developing qualification programs for casting processes and inspection plans.
• Aerospace OEMs and subcontractors specifying casting procurement requirements and approving suppliers.
• Inspectors and certification bodies verifying that pre-production and production castings conform to the required aerospace material standards.

Using EN 2076-3 helps ensure consistent material origin, validated manufacturing processes, and traceable inspection for critical aluminium and magnesium cast components.

Related Standards

• EN 2076-1 - general technical specification (use in conjunction with Part 3)
• EN 2076-2 - material composition and properties requirements (material compliance mandated by Part 3)
