8.6.7 Determination of the resistance against corrosion and creeping after 8.6.8 Determination against climatic impact like weathering and UV-resistance

mechanical impact
The weathering test is carried out on sample plates conform to DIN EN ISO 11341. First use

The mechanical impact is carried out with a sharp edged falling mass. a cycle of temperature and humidity of 12 hr, 10-50 °C, 30-75% relative humidity. Then
Height of fall: 300 mm use the water corrosion test related to DIN ISO 2744 using 80 °C and 3 days. Finally the
Weight of mass: 0.2 kg plates must be inspected for corrosion, partial detaching of the surface or any change of
Material of mass: like steel 1.2210 the surface structure.
Hardness of mass: > 60 HRC

Geometry of mass: Conus 60 °, radius r = 2 mm

Afterwards the test plate with the impact spot is taken in a water resistance test as de-
scribed in EN ISO 28706-3, with a deviating solution of distilled water, using a
temperature of 80°C during 72 hours (3 days).
