Overview
EN 4400-1:2019 - part of the CEN Aerospace series - defines the technical specification for aluminium and aluminium alloy plate (clad or unclad) supplied in the as-rolled or machined condition. Prepared by ASD‑STAN and adopted by CEN, this standard sets requirements for ordering, manufacture, testing, inspection and delivery of plate used in aerospace applications. It supersedes earlier EN 2070 parts and forms part of the EN metallic material standards organized under EN 4258.
Key topics and technical requirements
- Scope and application: Applies when referenced on the drawing, order or inspection schedule and is to be used with the applicable EN material standard.
- Wording of order: Orders must specify quantities, delivery dates, material standard number, delivery condition, dimensions and tolerances (or dimensional standard reference), packing, surface protection and any special tests.
- Manufacture and inspection: A manufacturing schedule shall be established in accordance with EN 2078. Products must be free from irregularities that would prejudice manufacture or use.
- Heat treatment and forming: Definitions and provisions for solution heat treatment, controlled stretching and machined/parent plate are included (e.g., continuous furnace runs).
- Qualification and release testing: Defines qualification phases, manufacturer responsibility for release tests, purchaser’s right to witness tests, and procedures for replacement/retests and rejection.
- Special test regimes: Capability clause, statistical process control and purchaser‑requested special tests are addressed.
- Traceability and documentation: Each delivery must include an inspection and test report per EN 2078 with manufacturer ID, order number, statement of compliance, material and delivery condition, dimensions, batch/cast numbers, heat treatment and test results.
- Health & safety: Products must comply with applicable laws and a product safety data sheet must be available.
- Patent caution: The foreword notes possible patent rights and places responsibility on users to identify these.
Practical applications and users
- Who uses it: Aerospace material suppliers, plate manufacturers, procurement officers, QA/QC managers, testing laboratories, design and stress engineers, and certification bodies.
- Typical uses: Specification and acceptance of aluminium plate for airframe structures, structural components, skin panels and other aerospace parts where consistent metallurgical condition, mechanical properties and documented traceability are required.
- Value: Ensures uniform ordering language, agreed test methods and clear release criteria to support reliable supply chains and regulatory compliance in aerospace manufacturing.
Related standards (examples to consult)
- EN 2078 (manufacturing/inspection schedule), EN 4258 / EN 4259 (series organization and terms), EN 515 (temper designations), and test method series (EN 2002, EN 2004, EN 2716, EN 2720, EN 4050-4, EN 6018, EN 9100).

Where "ramping" to the heat treatment temperature is allowed in the material standard and is used, this shall be stated in the inspection and test report. Where the use condition is not the delivery condition the inspection and test report shall detail the heat treatment applied to the test samples representing the use condition: see line 8.3.
8.1 Test sample(s) (1 of 2) • For machined plate, the thickness before machining shall govern the requirements of sampling, testing and determination of acceptance limits. • Test samples shall be selected such that they are clear of any stretcher jaw marks. • Test samples shall not be worked after removal from the product they represent. • Test samples and associated test pieces shall be identified in such a manner that their orientation with respect to the product and batch is maintained. Where the product is supplied in the use condition and hardness and / or electrical conductivity testing is used for batch uniformity assessment, see line 82, then such testing shall be carried out prior to selection of the tensile test sample(s). In such cases the product(s) showing the lowest hardness / highest electrical conductivity values shall be selected for the requisite tensile testing as stated in the table below. The number of parent plates to be tested per batch shall be as shown in the following table, although this number may be reduced by written agreement between manufacturer and purchaser if the manufacturer can demonstrate that the requirements of the relevant material standard are consistently met. −
