Requirements for processed black-and-white films having silver-gelatin type emulsions on safety cellulose ester type bases.

1.1 This International Standard establishes the specifications for safety cellulose ester type films having silver-gelatin type emulsions processed to produce a stable black-and-white photographic image.

1.2 Silver images produced by full reversal processing are included. Silver images that have been chemically altered by treatments such as toning, reduction, or intensification are excluded. Colour films are excluded. However, a gold protection treatment is not excluded. Silver images produced by dry processing, diffusion transfer, monobath processing and halide reversal processing are also excluded.

1.3 This International Standard is applicable to microfilm, motion-picture film roll film, and sheet film intended for archival record films.

1.4 Lacquers and lubricants have been applied to processed film for fungus and scratch protection without any known detrimental effect on permanence. However, because of the wide variety of possible materials, lacquered and lubricated film are excluded from this International Standard.
