Scope

This document describes the equipment, methods, and procedures for generating ozone, as well as measuring and quantifying the amount of changes in digital hardcopy images and traditional analog color photos caused by this exposure.
The test method described in this document involves conducting accelerated testing by increasing the ozone level. If the main "gas fading" medium of the system is not ozone, this method may not be applicable and may yield misleading results in terms of the test images' resistance to contaminated air.
