General Information

Overview
EN 2559:2022/A1:2024 is a CEN (ASD‑STAN) aerospace standard that specifies laboratory methods to determine resin content, fibre content, and the mass of fibre per unit area for carbon, glass and aramid fibre preimpregnates (prepregs). The 2024 amendment (A1) updates several procedural references and the mass‑measurement definitions used in the standard methods to improve clarity and ensure consistent test implementation across laboratories and suppliers.
Key topics and technical requirements
- Scope: Applies to fibre preimpregnates used in aerospace applications - carbon, glass and aramid fibres impregnated with resin.
- Measurement focus: Determination of resin fraction, fibre fraction and areal fibre mass (mass of fibre per unit area).
- Test methods: The standard includes multiple test routes (commonly identified as Method A, Method B and Method C). These involve controlled heating, solvent extraction and mass measurements of specimen plus test fixtures (thimbles or containers).
- Amendment A1 changes:
- Method A: corrected reference for the heat‑source temperature range from clause 7.4.2.1 to 7.4.2.3.
- Method B: clarified the mass definitions for the thimble and specimen after solvent extraction (definitions for m4, m5 and m6).
- Method C: clarified the mass definitions for containers and dry residue after extraction (definitions for m7, m8 and m9).
- Equipment and controls: Requires a heat source with suitable temperature control and solvent‑extraction apparatus; precise weighing of thimbles/containers and residues is fundamental.
- Data outcomes: Results expressed as percentages (resin/fibre content) and as areal density (g/m2 or similar) for fibre mass per unit area.
Applications
- Quality control and incoming inspection of aerospace prepreg materials.
- Supplier qualification and batch certification of carbon, glass, and aramid prepregs.
- Material characterization for design, manufacturing process development and failure analysis.
- Regulatory and procurement compliance where verified material content and areal fibre mass are required.
Who should use this standard
- Composite material test laboratories and QA/QC teams in aerospace OEMs and Tier‑1 suppliers.
- Prepreg manufacturers and material suppliers for product control and specification compliance.
- Engineers and technicians involved in composite layup, process validation and material traceability.
- Certification bodies and auditors assessing material conformity.
Related information
- Base document: EN 2559:2022 (amended by EN 2559:2022/A1:2024).
- Issuing organizations: CEN and ASD‑STAN; national adoption expected across CEN member bodies.
Keywords: EN 2559:2022/A1:2024, prepreg testing, resin content, fibre content, fibre mass per unit area, aerospace composites, solvent extraction, areal density.
