Abstract
A method for determining variations in properties of a sample exposed to artificial weathering includes the steps of irradiating the sample at a wavelength substantially in the range of 295 to 400 nm in an intensity at least five times that of solar radiation, and continuously measuring intensity, spectral distribution or both intensity and spectral distribution of radiation reflected by or passing through the sample.

A method for determining variations in properties of a sample exposed to artificial weathering, comprising the steps of:
- irradiating the sample-with radiation in a spectral range simulating solar radiation at a wavelength substantially in the range of 295 to 400 nm in an intensity at least five times that of solar radiation;
- and
- continuously measuring intensity vs. wavelength of radiation reflected by or passing through the sample.
