Photographic Activity Test (PAT)
Article number:

Norm:
ISO 18916
The Photographic Activity Test (PAT) tests the suitability of archival materials for the preservation of silver halide-based photographs. The standard describes a test procedure in which material samples are brought into close contact with special detector materials at 70 °C and 86 % relative humidity over a longer period of time.
The metrological evaluation of the detector materials before and after incubation then provides a statement as to whether a material is suitable as an archival material for silver halide photographs or not.
