Abstract
ISO 18924:2013 specifies a test method for the prediction of certain physical or chemical property changes of imaging materials.
ISO 18924:2013 is applicable to the Arrhenius test portion of ISO 18901, ISO 18905, ISO 18909, ISO 18912 and ISO 18919.
ISO 18924:2013 is applicable to the prediction of the optical-density (D) loss or gain of imaging materials. Photographic dye images may be produced by chromogenic processing, by formation of diazo dyes, or by non-chromogenic methods such as dye diffusion and silver dye-bleaching processing. ISO 18924:2013 also covers density changes caused by
- residual coupler changes in dye images,
- excess residual processing chemicals in silver black-and-white materials,
- temperature effects on thermally processed silver images.
This International Standard is applicable to the prediction of support degradation.
