TESTS
3.1
Resistance to artificial weathering in a UV-chamber. For testing aging effects of UV-radiation in the presence of moisture the liquid applied roof waterproofing kit was tested corresponding to the specified characteristics of the system according to the test conditions for the climatic zone given in the chapter results according to EOTA Technical Report 010 “Exposure procedure for artificial weathering” using fluorescent tubes (UV-A) with the following conditions: Testing device and parameter: Testing device: Sample rotation:
Weiss UV-Global UV 200 RB reordering every 2 weeks
Test parameters for UV-radiation: Light source type: fluorescent light source, according to EN ISO 4892-3 Standard-black-temperature: 60 °C ± 3 °C Spray cycle: 1 h spraying at 23 °C 5 h dry period at 60 °C and 10 % r.H. Exposure time: 2000 h
