EspañolWeathering resistance
Test as per ISO 10354-2
The Calmmoon noise suppression sheeting was placed in a water bath, the temperature of which was cycled between 0ºC and 80ºC. One cycle lasted 7 minutes.
Once the specified number of cycles had been completed, the sample was taken from the water bath and the vertical absorption degree was determined as per ISO 10534-2.
A significant temperature change takes place statistically on 100 days per year. 3,000 temperature cycles correspond to 30 years of use.
Result: no effect on the noise damping quality.
Water resistance
The Calmmoon noise suppression sheeting was placed in a water bath.
The sample was taken from the bath after 48 hours, dried and the vertical absorption degree was measured as per ISO 10534-2.
Result: no effect on the noise damping quality.
ZAM clip fastening
The clip fastening consists of galvanised sheet steel plus aluminium and magnesium (ZAM technology). This ensures that the "interfaces" of the galvanised steel are additionally protected by aluminium and magnesium and the clip fastening remains free from corrosion and functions safely even when used on track near salt water.
