SKZ Uses Atlas Weather-Ometer® to Measure Impact of Surface Temperature on Plastics

Linsengericht, Germany July 2013 – SKZ, one of Europe’s leading accredited and certified quality assurance institutes, has launched a research project to better predict the impact of surface temperature on the weathering behavior of plastics.

A critical factor in the project is the surface temperature of the plastic specimens, which may differ in natural weathering when compared with accelerated laboratory weathering. To assist in that effort SKZ has enlisted the aid of Atlas Material Testing Technology, the global leader in weathering technology and services.

Surface temperature has a significant impact on the aging behavior of plastics as they weather. To improve the comparison of laboratory and outdoor exposures, specimen surface temperatures need to be measured and taken into account during laboratory weathering. To accomplish this, SKZ has incorporated the  Ci4000 Weather-Ometer® with its new Specific Specimen Surface Temperature System™ (S3T) from Atlas Material Testing Technology  into its project. The Ci4000 Weather-Ometer continuously reads specimen surface temperatures with a pyrometer and assigns a measurement to the respective specimen via an RFID tag. Each specimen’s weathering behavior is characterized by color and physical properties.

By including surface temperature measurement into the predictive model, artificial laboratory weathering is better correlated with natural, outside weathering. The weathering sequences are then analyzed and described with a modified Arrhenius model.
