This International Standard specifies the principal physical and chemical requirements for filing enclosures, albums, and containers particularly designed for storing processed photographic films, plates and papers. The photographic image may be silver-gelatin type, colour (dye-gelatin), diazo or vesicular.
This International Standard applies to storage copies and does not include work copies as defined in informative annex B. The requirements are limited to the characteristics that may affect the enclosed item chemically or physically when it is stored under recommended conditions. (For methods of proper storage, see ISO 18911, ISO 18918 and ISO 18920, see [12, 14, 16] in the bibliography.)
