Phạm vi áp dụng / Scope of standard

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

It applies specifically to films with a base of safety cellulose ester
or polyester [poly(ethylene terephthalate)] having silver-gelatin
emulsions, processed to produce a black-and-white silver image by
negative or full-reversal processing. It applies to film processed by a
monobath which includes thiosulfate as the fixing agent followed by a
conventional wash. It also applies to silver films given a stablizing
treatment by partial or full conversion to silver sulfide, silver
selenide or gold.

This International Standard does not apply to films with 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. It does not apply to films that
have been processed by a monobath using 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 [Footnote 10].

This International Standard does not apply to films to which lacquers
have been applied.

This International Standard applies 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.
