This International Standard establishes the specifications for silver-gelatin photographic reflection prints intended for dark storage. It covers silver-gelatin print types of all weights.

This International Standard applies to wet-processed black-and-white silver-gelatin photographic prints, including those that have been chemically treated (with a gold, selenium, sulfur, or other chemical treatment bath) to improve the permanence of the silver image. It also applies to silver-gelatin prints processed by a monobath, which includes thiosulfate as a fixing agent followed by a conventional wash.

This International Standard is not applicable to instant black-and-white photographic prints, stabilization-processed black-and-white prints (those where the undeveloped silver halide has been chemically converted and not removed), or thermally processed black-and-white prints. It does not apply to colour or dye-based photographic prints, nor to prints that have been processed by a monobath using other than a thiosulfate-type fixing solution, or prints where the silver salts are rendered more soluble by means other than thiosulfate.

Laminated and adhesive mounted reflection prints, prints on poly (ethylene terephthalate) support, and prints that have been displayed are also excluded from this International Standard.
