ISO 18901:2010确立了用于存储记录的摄影胶片的规范。
ISO 18901:2010特别适用于以安全纤维素酯或含银明胶乳液的聚酯为基底的薄膜,通过负片或完全反转处理,处理后产生黑白银图像。它适用于使用包括硫代硫酸盐作为固色剂的单浴处理的薄膜,然后进行常规清洗。它也适用于通过部分或全部转化为硫化银、硒化银或金进行稳定化处理的银膜。
ISO 18901:2010适用于具有超声波或电介质(感应加热)拼接的薄膜。它不覆盖由胶带或溶剂型龙头制成的拼接膜。
ISO 18901:2010不适用于具有彩色黑白图像、任何类型的彩色图像或具有磁记录磁道的胶片。它不适用于通过干燥或热处理或扩散产生银图像的薄膜-
反转处理,或使用硫代硫酸盐型固定溶液以外的方法通过单浴处理的薄膜。它不适用于通过硫代硫酸盐溶液以外的方法去除银盐的薄膜。
ISO 18901:2010不适用于涂有油漆的薄膜。
ISO 18901:2010 establishes the specifications for photographic films intended for the storage of records.
ISO 18901:2010 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.
ISO 18901:2010 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.
ISO 18901:2010 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.
ISO 18901:2010 is not applicable to films to which lacquers have been applied.
