Free Webinar: Temperature Control in Accelerated Laboratory Weathering Testing of Plastics

Presented by Q-Lab 

Accelerated weathering testing is used widely to evaluate the performance of outdoor polymeric materials. These tests apply ultraviolet (UV) light, high temperature, and water in the form of condensation, humidity, and spray. Control of temperature during accelerated weathering testing is critical for many plastic materials, both to control the rate of photochemical degradation and to avoid unrealistic failure modes from plastics softening or even melting. Unfortunately, maintaining proper specimen temperature during accelerated weathering testing can be challenging and is often not well-understood.

This presentation will present specimen temperature data recorded for both fluorescent UV and xenon arc accelerated weathering testers using various specimen material types and mounting configurations. Test temperatures in both types of apparatus are commonly controlled by a “black panel” reference temperature sensor and also often by specifying chamber air temperature. Data will be presented illustrating the relationship of black panel temperatures to air temperatures in weathering test chambers, differences in temperatures experienced by metal and plastic specimens, and the influence of three-dimensional specimen mounting in fluorescent UV testing.
