Résumé

This International Standard establishes specifications for the stability of photographic films intended for storage of

records; specifically, microfilms with a base of safety polyester [poly(ethylene terephthalate)] having predominantly

silver behenate salts dispersed in nongelatinous emulsions, and thermally processed to produce a black-and-white

silver image.

This International Standard applies to thermally processed silver (TPS) microfilms having ultrasonic or dielectric

(induction-heated) splices. It does not cover films with splices made by means of adhesive tape.

This International Standard does not cover other types of black-and-white TPS films, black-and-white paper, colour

images and colour prints that are produced with thermally processed silver behenate systems.

It does not apply to films to which lacquers have been applied.

It also does not apply to conventional black-and-white silver images that are produced by wet processing of silvergelatin

films (see ISO 10602).
