Imaging materials. Processed imaging materials. Photographic activity test for enclosure materials Ingestion-build-63114 BS ISO 1070:2018 has been1 Scope This International Standard specifies the procedure for the photographic activity and dye coupler reactivity tests. 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 such as adhesives, inks, paints, labels, and tape. This International Standard evaluates possible chemical
