DIN ISO 18901:2007 PDF

Scope: This International Standard establishes the specifications for photographic films intended for the storage of records. Itis applicable specifically to films having ultrasonic or dielectric(induction heated)splices.It does not cover films with splices made by means of adhesive tape or solvent-type splices. NOTE Solvent-type splices are suspect since they may 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,nor 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,nor to films that have been processed by a monobath using a 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 [10]in the bibliography). This International Standard is not applicable to films to which lacquers have been applied.
