Glazing

• Measure pressure resistance: Simulate pressure changes produced when two trains cross each other in the open air or in tunnels – on all types of glass panes (flat or curved, new or downgraded, etc.)
• Measure soft body impact resistance: Check that a person inside a vehicle is not projected outside after the impact of a 50 kg pendulum
• Check water tightness
• Check hard body impact resistance
• Assess rupture strength of the structural bonded seal
• Measure Dew Pointsée

• Two test rigs
  – Pressure up to +/- 8,000 Pa
  – Sine, rectangular or square wave (on request)
  – Frequency up to 6 Hz
  – Rig dimensions: 1,800 x 2,500 mm
• Watering system (used during test)
• Dynamic measurement system of glass pane deflection
