ISO 18914:2013规定了一种实验室试验方法，用于测定感光乳剂或明胶背衬在加工过程中的耐磨性。 该方法可用于确定加工溶液、明胶层性质、加工溶液温度和时间的变化，或这些因素的组合对明胶层耐湿划伤性的影响。 本方法适用于测定照相乳剂湿润时的物理完整性。

ISO 18914:2013 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.
