Climatic ageing
Evaluate the impact of weather on railway components.
Tests objectives
Perform climatic ageing tests on infrastructure and rolling stock components. Three types of tests:
- Development
- Approval (type tests)
- Investigation (after technical malfunction)
Tests facilities
- Climatic test chambers with relative humidity ranging from 20% to 98%
– 14 m3: from -40 (±3 °C) to 125 (±5°C)
– 1.5 m3: from -40 (±3 °C) to 125 (±5°C)
– 1.5 m3: from -60 (±3 °C) to 160 (±5°C) - Salt mist test chamber (1.2 m3)
- Spraying systems for Ingress Protection (IP) tests
- Facilities dedicated to UV resistance testing of materials
