The work of preparing International Standards is normally carried out through ISO technical committees. E
11、ach member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internati
12、onal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standard
13、s adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of

ISO shall not be held responsible for identifying any or all such patent rights.ISO 18924 was prepared by Technical Committee ISO/TC 42, Photography.This second edition cancels and replaces the first edition (ISO 18924:2000), of which it constitutes a minor revision with the followin

16、physical or chemical property changes of imaging materials.This International Standard is applicable to the Arrhenius test portion of ISO 18901, ISO 18905, ISO 18909, ISO 18912, and ISO 18919.This International Standard is applicable to the prediction of the optical-density (D) loss or gain of imagi
17、ng 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. This International Standard also covers density changes caused by residual coupler changes in dye imag
18、es, 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. One such example is the generation of acetic acid by degradation of cellulose ace
19、tate film support. Another example is the change in tensile energy absorption of black-and-white paper support.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1Arrhenius plotplot of the logarithm of the time for a given change in a characteristic
