Abstract
Methods for directly comparing the light spectral power distribution of a natural light source to the light spectral power distribution received on the target area of an outdoor accelerated weathering device, comparing the spectral measuring assembly on accelerated weathering devices with traceable spectral measuring assemblies measuring the same light source at the same instant in time, comparing different outdoor accelerated weathering devices to one another with respect to continuous direct measurement of each such device in a collection relating the quality of each single device back to a single standard measured by all devices and rationalizing the results of different methods of weatherability testing.
