accelerated weathering

Exposure to natural weathering in Florida, based on ISO 2810
Testing of the panels takes place in Miami, in a south-facing location. The warm and humid climate of south Florida is ideal for real-time weathering tests. The duration of weathering will depend upon the system to be tested: 1 year for standard polyesters, 3-5 years for superdurables, and 10 years for fluoropolymers.

Accelerated weathering based on EN ISO 11341
An accelerated weathering test simulates, over a short period of time, the influence of moisture, temperature, and of the destructive components of sunlight that a coating has to endure for outdoor application.

It serves to differentiate the quality level with reference to the ‘standard’, ‘superdurable’ and ‘hyper-durable’ weathering specifications. Due to the testing duration, this test provides figures with very good comparability to those obtained from exposure to natural weathering in Florida. Testing duration: 300 hours.

UV-B 313nm based on DIN 53384
A UV-B test simulates, over a short period of time, the influence of UV radiation on the surface finish. This is an even faster test method for determining the weathering stability.
