In the field of weathering tests we offer you the following services:

Atlas 440 xenon-arc lamp test in accordance with ISO 16474-2
The xenon-arc lamp test is the most useful quick test for assessing the weathering resistance of coating systems, because it imitates the effects of sunlight more accurately than other test processes.

Typical test duration: 1000h

UV-B 313 nm test in accordance with ISO 16474-3
Comparative short-term weathering test using concentrated UV-B radiation with a wavelength of 313 nm. A quick and cost-effective method of evaluating binder systems.

Typical test duration: 300–600h

UV-A 340 nm test in accordance with ISO 16474-3
Comparative short-term weathering test using concentrated UV-A radiation with a wavelength of 340 nm. A quick and cost-effective method of evaluating binder systems.

Test duration: by agreement

Natural weathering test in Florida in accordance with ISO 2810
This long-term test is carried out in Florida. The duration depends on the type of coating system:

- 1 year for standard polyester facade coatings

- 3 years for highly weather-resistant systems

The natural weathering test in Florida provides extremely reliable results and avoids all of the uncertainty of the short-term weathering tests.
