Overview

EN 4400-6:2019 is a European aerospace standard that defines the technical specification for aluminium alloy forging stock. It covers ordering, manufacture, testing, inspection, marking and delivery of both wrought forging stock (produced by extrusion or hot rolling) and cast forging stock. This standard is intended to be used together with the relevant EN material standard and is normally applied when the forging stock manufacturer is not the producer of the final forgings.

Key topics and requirements

• Scope and application
  • Applies to aluminium alloy forging stock for aerospace use; used when referenced by material standards or procurement documents.
• Wording of order
  • Orders must specify quantities, delivery dates, material standard number, delivery condition, dimensions/tolerances, packing and any special test requirements.
• Manufacture and manufacturing schedule
  • Manufacturer must define raw materials, processes and inspections in a manufacturing schedule per EN 2078; changes that could affect quality require purchaser notification/approval.
• Testing, inspection and release
  • Manufacturer is responsible for release testing; purchaser may witness or perform tests.
  • Tables in the standard (Tables 1 and 2) map specific technical requirements to material-standard line references.
  • Chemical analysis samples should be representative (typically 1 per cast unless otherwise stated).
• Retests, rejection and special tests
  • Retest procedures are specified; failure to meet material-standard requirements is cause for rejection.
  • Purchaser can require special tests which must be agreed and documented.
• Capability clause and statistical control
  • Allows reduced routine testing where statistical evidence demonstrates capability (with purchaser agreement); statistical process control may support reduced release testing.
• Marking and traceability
  • Products must be marked or fully traceable to cast/production/heat-treatment batches; marking must not damage material or promote corrosion.
• Delivery documentation
  • Inspection and test reports shall conform to EN 2078 and include manufacturer identification, order number, statement of compliance with EN 4400-6, material standard, delivery condition, dimensions, batch/cast numbers and test results.
• Health & safety
  • Products must comply with applicable health and safety laws and a product safety data sheet must be available.

Practical applications and users

• Who uses EN 4400-6:2019
  • Aerospace material suppliers, forging-stock manufacturers, forging shops, OEMs, procurement and quality managers, inspection laboratories and certification bodies.
• Why it matters
  • Ensures consistent specification, quality, traceability and testing of aluminium forging stock used in aircraft and space components; facilitates supplier–purchaser agreements and regulatory compliance.

Related standards

• EN 4258 (organization of metallic material standards)
• EN 2078 (manufacturing/inspection schedules & inspection/test reports)
• EN 515 (temper designations)
• EN 2002-1, EN 2715, EN 4050-4 and other aerospace series test-method standards

Keywords: EN 4400-6:2019, aluminium alloy forging stock, aerospace standard, forging stock specification, release testing, traceability, capability clause.
