4.1 Good adhesion is a prime consideration for print media. For coated papers failure can occur between the coating and the substrate or between coated layers, while for uncoated papers failure can occur between the imaged area and the substrate. This practice utilizing mechanical stress allows comparative studies of print media by examining adhesion in both printed and unprinted areas.

4.2 Factors in the office and outdoor environments, such as heat, cold, thermal shock, ultraviolet/visible radiation and water vapor can have a similar effect on adhesion as mechanical stress.

4.3 This practice is used to obtain comparative data of adhesion strength of print media.

1.1 This practice describes procedures to obtain subjective, but comparative data for adhesion of print media used in printers, copies and other reprographic devices.

1.2 This method is applicable to constructions where the print media is subject to failure under mechanical stress from mostly peel conditions (that is, paper, film, cloth, and so forth).

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
