Ultra-Accelerated Weathering II: Considerations for Accelerated Data-Based Weathering Service Life V on materials obeying strict reciprocity and materials deviating from strict reciprocity are considered. A second new high-intensity natural UV weathering device is introduced based on ASTM G90. The paper presents data from two materials degrading under different intensities of UV and compares natu

Quantitative Mapping of Mechanisms for Photoinitiated Coating Degradation,assumptions underlying existing models for thermoset coatings are analyzed and suggestions for further work provided. A modeling approach that can be used to implement the various effects of water on the degradation mechanisms of cross-linked coatings is also presented and experiments to test the ap

Impact of Environmental Factors on Polymeric Films Used in Protective Glazing Systems,y (FTIR), ultraviolet–visible spectroscopy, and tensile tests. Accelerated conditions involved simultaneous exposure of specimens to ultraviolet (UV) radiation between 295 and 450 nm and each of four temperature/relative humidity (RH) environments, i.e., (a) 30 °C at <1 % RH, (b) 30 °C at 80 % RH, (

Accelerated Testing: Understanding Experimental Design and Error Propagation,erformance degradation over that time span impractical. The ability to make reliable estimations of product performance over long periods of time based on measurements made over a relatively short time period becomes an important need for the designer.
