标准范围

本文件描述了产生已知臭氧暴露的设备、方法和程序，以及数字打印硬拷贝图像和传统模拟摄影彩色打印图像因该暴露而产生的变化量的后续测量和量化。本文件中描述的试验方法使用增加的臭氧水平来实现加速试验。如果系统的主要“气体褪色”机制不是臭氧，则该方法可能不适用，并且可能会在测试图像对污染空气的阻力方面给出误导性结果。

This document describes the equipment, methods and procedures for generating a known ozone exposure and the subsequent measurement and quantification of the amount of change produced within both digitally printed hardcopy images and traditional analogue photographic colour print images due to that exposure.The test method described in this document uses increased levels of ozone to achieve an accelerated test. If the principal "gas fading" mechanism for a system is not ozone, this method might not be suitable and might give misleading results as to resistance of the test image to polluted air.
