We can determine the technical properties for paper, folding carton and corrugated board as well as for plastic materials, .
UV testing on laboratory level – as in ASTM G53 – allows us to perform short term qualitative controls on materials instead of exposing the material during 5 to 10 years at the sunlight.
The equipment has to comply with ASTM G53/96 and equipped with fluorescent UV-B lamps.
The test samples are exposed in alternation to UV light and condensation in a repetitive cycle of 200 hours.
The test cycle includes 8 hours UV radiation at a temperature of 60° C followed by 4 hours condensation at 50°C.
After 200 hours exposure, the breaking strength and extension are determinated in accordance with ISO 13934-1.
The obtained values are compared with the test samples conditioned in the dark on cool temperature.
All load bearing materials of the FIBC must – after testing – maintain 50% of their original breaking strength and extension.
