Overview
EN 2715:2018 (CEN) specifies the procedure for the macrographic examination of the cut surface from aluminium and aluminium-alloy wrought products, forging stock and forgings. The standard describes selection and preparation of test samples, etching to reveal macrostructure and basic examination and acceptance principles. Health and safety requirements are not covered; users must adopt appropriate precautions when hazardous substances are involved.
Key Topics
Selection of test samples
- Samples shall be taken as required by the relevant technical specification, material standard, drawing, order or inspection schedule.
- For plate, samples shall be at least 200 mm long and taken from full thickness, normal to the rolling direction.
Preparation of test samples
- Wrought products in heat-treatable alloys that are not solution treated shall be solution treated (or solution treated and artificially aged) in accordance with the material standard before examination; artificial ageing may be omitted if it facilitates macrographic examination.
- Surfaces to be examined shall be machined and/or polished without modifying the macrostructure or causing overheating.
Etching reagents (recommended)
- For non-heat-treatable alloys and AL-P6XXX series: recommended reagent mix by volume is 30% nitric acid (70% conc.), 30% hydrochloric acid (35% conc.), 3% hydrofluoric acid (40% conc.), and 37% demineralised water.
- For AL-P2XXX, AL-P7XXX and aluminium-lithium alloys: recommended reagent mix by volume is 15% sulphuric acid (99% conc.), 10% hydrofluoric acid (40% conc.), and 75% demineralised water.
- After etching: rinse in water, desmutt in 70% nitric acid, then rinse and dry.
Examination and acceptance
- Prepared test samples shall be examined with the naked eye or at low magnification to reveal macrographic features.
- Acceptance criteria are determined by the relevant technical specification, material standard, drawing, order or inspection schedule.
Applications
EN 2715:2018 is primarily used by aerospace manufacturers, inspection laboratories, forging shops and quality engineers who need a consistent, repeatable method to reveal and assess macrostructure in aluminium products. Practical applications include:
- Incoming material verification for wrought products and forgings
- Process control during forging and heat treatment
- Non-destructive follow-up inspection planning and documentation
- Contractual inspection clauses between manufacturer and purchaser
Adoption of the standard supports traceable inspection records and consistent interpretation of macrographic features across suppliers and OEMs.
Related Standards
- The document contains no normative references but explicitly defers to relevant technical specifications, material standards, drawings or inspection schedules for acceptance criteria and sampling requirements.
- For terminology and related standardization resources see IEC Electropedia and ISO Online Browsing Platform (as referenced in the standard).
For implementation, pair EN 2715:2018 procedures with the applicable alloy material standards and the purchaser's inspection schedule to ensure compliant, auditable macrographic examination workflows.
