1.1 This practice covers specific procedures and test conditions that are applicable for xenon-arc exposure of ink jet media prints conducted in accordance with Practices G151 and G155. The laboratory accelerated procedure is intended to determine the relative lightfastness of ink jet prints in office environments where window filtered daylight is used for illumination.

1.2 The two criteria used to determine relative lightfastness are instrumental color change and change in optical density.

1.3 This practice is useful in determining the relative lightfastness of a series of prints or the relation of the lightfastness of the print of interest to the performance of controls with known lightfastness exposed simultaneously.

1.4 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. Specific precautionary statements are given in section 8.

1.5 There is no equivalent ISO standard.
