Ice Covered Test Chamber – Artificial Icing Lab – BONAD Environmental Test Chamber
Key Applications
This versatile chamber is critical for testing in numerous sectors:
- Power & Electrical Industry: Testing composite insulators, power line components, insulators, and electrical equipment under icing and polluted conditions.
- Aerospace: Research and certification testing for wing de-icing systems, engine inlets, sensors, and aerodynamic surfaces (aligned with FAA and SAE standards).
- Wind Energy: Evaluating ice accretion on wind turbine blades and its impact on performance and structural integrity.
- Automotive & Rail: Testing sensors, cameras, and braking systems in icy conditions.
- Scientific Research: Studying the fundamental physics of ice accretion and the environmental impact on materials and structures.
Standards Compliance
Our ice-covered test chambers are designed to meet rigorous international testing standards, including:
- ISO 12494: Atmospheric icing of structures (The authoritative international standard for icing loads).
- IEC 60815: Selection and dimensioning of insulators for polluted conditions (covers icing).
- IEC 60060-1: High-voltage test techniques.
- FAA AC 20-73A: Aircraft ice protection system certification guidance.
- SAE ARP5485: Definitions of icing terms for aerospace.
