This International Standard specifies the procedure for the photographic activity and dye coupler reactivitytests.This International Standard is applicable to general photographic enclosure materials such as paper, tissue,cardboard, mat board and plastics. It is also applicable to components of photographic enclosure materials suchas adhesives, inks, paints, labels, and tape.This International Standard evaluates possible chemical interactions between enclosures with processedsilver-gelatin, colour (dye-gelatin), inkjet prints made with dye-based and pigment-based inks, thermal dyediffusion transfer (“dye sub”) prints, digitally printed dye-diffusion-transfer prints, liquid- and dry-tonerxerographic prints, liquid-toner electrostatic prints, and diazo images after long-term storage. It does notpertain to harmful physical interactions such as blocking (sticking together), dye bleed, adhesive migration, orplasticizer exudation. It does not pertain to important criteria of enclosures such as their inherent chemicalstability, physical integrity, and workmanship. Passing the photographic activity test (PAT) does not indicatethat a material is archival. This term has no clear definition and is not used in this standard. Photo-safe,storage enclosures and their components are covered in ISO 18902, which includes passing the criteria of thephotographic activity test.If a particular brand of commercially made enclosure materials is found to be safe for long-term storagepurposes, there is no assurance that subsequent batches will contain the same ingredients of the same purity,chemical inertness, concentrations, or sound and sturdy construction. For this reason, materials are testedannually or upon each formulation or supplier change. For materials which are manufactured in a variety ofcolours, such as papers and inks, each colour is evaluated and reported separately.For enclosures intended for use with any of the above imaging processes, only the black-and-white PATdescribed in Clauses 4 to 7 are applicable. The dye coupler reactivity test is optional as the results are validonly for the specific colour print product being investigated. Different colour print products can have differentstaining sensitivities.For enclosures intended for use with diazo images, only the diazo PAT described in 8.5 is applicable.
