- Abstract
- In order to improve the scientific basis for predicting the photodegradation effects of UV radiation on macromolecular materials, an ongoing study of spectral UV measurement techniques is being conducted at NIST. This paper reports priminary results which indicate: 1) The importance of fine resulution - that is, a narrow measurement window - for spectral measurements of UV irradiance at the exposure site; and 2) The non-necessity of fine spacing in the center frequencies at which irradiance is measured. These findings are reported in the next two sections.
