UV Testing

Color change after 5 years* of ultraviolet light exposure is measured under fluorescent, sunlight and horizon lighting. Color change is measure in E units. Note: results of less that 10 E unites are considered to have little color change. Results of 20 or more E units are regarded as having a significant color change.

*Length of time is an approximate as no set standard exists for accelerated UV testing
