This International Standard specifies a laboratory test method for determining the resistance of photographic emulsions or gelatin backings to abrasion damage during processing.
This method may be used to determine the effects of variations in processing solutions, gelatin layer properties, processing solution temperatures and times, or a combination of these factors, on the wet scratch resistance of gelatin layers.
This method is applicable to the determination of the physical integrity of photographic emulsions when wet, but it is not applicable to the evaluation of the scratch resistance of the support material.
