1.1 This practice covers an accelerated procedure intended to determine the lightfastness of ink jet prints in office environments where overhead fluorescent light is used for illumination.
1.2 This practice describes two methods based on Method II and Method III from D 4674, in which specimens are exposed to cool white VHO fluorescent lamps (Method II) and cool white fluorescent lamps (Method III) under controlled environmental conditions.
1.3 Two criteria are used to determine relative lightfastness: color change and optical density.
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.
1.4 There is no known ISO equivalent standard.
