Significance and Use
4.1 This test method is a comparative test for determining the relative image stability of chemical carbonless paper samples.
4.2 The light source used simulates that of an office environment, while accelerating image fade.
1.1 This test method covers the determination of the image stability of chemical carbonless paper by exposure to fluorescent light for a controlled time period. Stability to light is determined by visual comparison between exposed and unexposed samples.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
