Overview

EN 3861:2013 - Aerospace series - Non-metallic materials - Glass transparencies - Material standard - Thermally tempered soda lime float glass is a CEN material standard that specifies requirements for universally available and high light transmission thermally tempered float glass plies intended for aerospace applications. Prepared under ASD‑STAN and published by CEN, this level‑3 standard defines material description, grades, delivery condition requirements and mandatory acceptance checks for glass transparencies used in aircraft structures.

Key topics and technical requirements

• Material type and formulation: Thermally tempered soda‑lime float glass intended as glass plies for aerospace transparencies.
• Grades and thickness ranges (characteristic 1.005):
  • Type A (universally available): A03 (0 < t ≤ 3 mm), A04 (3 < t ≤ 4 mm), A05 (4 < t ≤ 5 mm), A06 (5 < t ≤ 6 mm), A08 (6 < t ≤ 8 mm), A10 (8 < t ≤ 10 mm), A12 (10 < t ≤ 12 mm), A15 (12 < t ≤ 15 mm), A19 (15 < t ≤ 19 mm).
  • Type B (high light transmission): B08 (0 < t ≤ 8 mm).
• Optical performance:
  • Visible light transmission requirements given per grade (e.g., Type A grades > ~74.9% to >89%, Type B08 > 90.5%).
  • For Type B at 800 nm: transmission > 80.7%.
  • Haze: ≤ 1%.
  • Refractive index: n = 1.52 ± 0.01.
• Physical properties:
  • Density: 2.50 ± 0.02 g/cm3.
  • Linear thermal expansion: 88.5 ± 3.5 ×10‑7/K.
  • Surface compression stress and modulus of rupture: to comply with limits agreed during product qualification (specified during qualification).
• Delivery and processing:
  • Supplied in the final condition of use.
  • Storage: suitable conditions avoiding surface condensation.
  • Dimensional tolerance, flatness and optical distortion referenced to EN 3001.
• Testing and acceptance: Batch acceptance test titles and acceptance criteria are highlighted and mandatory for routine acceptance.

Applications and users

• Practical use: specification and procurement of tempered soda‑lime float glass plies for aircraft transparencies such as cabin windows, cockpit panels and other transparent panels requiring certified optical and mechanical properties.
• Primary users:
  • Aerospace OEMs and Tier‑1 suppliers specifying materials.
  • Materials engineers and designers selecting glass plies for transparency systems.
  • Quality assurance, test laboratories and certification authorities performing qualification and batch acceptance.
  • Procurement teams ensuring compliance with CEN/ASD‑STAN requirements.
