5.1 The degree of image abraded from a copy or printed image may be affected by various factors, including the type of machine, condition of the machine, supplies employed, time since imaging, and environmental conditions. As many as possible of these variables should be controlled during the test. If available, a control sample with known characteristics should be run along with the test samples.

5.2 This test method may be used to determine image resistance to damage or deterioration as a result of exposure to abrasive forces, such as automated document handling devices.

5.3 This test method may be used for control of product quality, comparative analysis of machines, comparative analysis of imaging components, as well as a research and development tool.

5.4 This test method is adaptable to images produced from most nonimpact printers and copiers. The printers shall be capable of utilizing the available program to produce the specified image.

5.5 If the user wishes to simulate the type of damage or smudge resulting from paper rubbing against the printed image or from normal handling, consideration should be given to using either the Crockmeter Method (Test Method F1319), the Sutherland Rub Method, or the Gavarti GA-CAT Method.
