Scope

This International Standard establishes the specifications for photographic films intended for the storage of records. It is applicable specifically to films with a base of safety cellulose ester or polyester having silver-gelatin emulsions, processed to produce a black-and-white silver image by negative or full-reversal processing. It applies to film processed using a monobath that includes thiosulfate as the fixing agent, followed by a conventional wash. It also is applicable to silver films given a stabilizing treatment by partial or full conversion to silver sulfide, silver selenide or gold. This International Standard is applicable to films having ultrasonic or dielectric (induction-heated) splices. It does not cover films with splices made of adhesive tape or solvent-type spIices. NOTE Solvent-type splices are suspect since they sometimes retain traces of residual solvents containing peroxide, which can pose some risk of oxidative attack on the silver image. This International Standard is not applicable to films with chromogenic black-and-white images, colour images of any type, or to films with a magnetic recording track. It does not apply to films with silver images produced by dry or thermal processing or by diffusion-reversal processing, or to films that have been processed by a monobath using means other than a thiosulfate-type fixing solution. It is not applicable to films where the silver salts are removed by means other than thiosulfate solutions (see Reference [10]). This International Standard is not applicable to films to which lacquers have been applied.
