标准摘要
[中文适用范围]： 本国际标准规定了测定和定量表示摄影胶片耐折度的方法。 该方法基于附录 B 中描述的 MIT 耐折度测试仪。 它是一项分析测试，并非旨在模拟实际使用条件。 本国际标准适用于有或没有明胶背衬的薄膜。 它也可以应用于原始薄膜或加工过的薄膜，尽管给定薄膜的柔韧性水平在加工后可能有很大不同。 可以使用与本国际标准中描述的类似的设备，前提是在使用此类设备获得的结果与使用所述设备获得的结果之间建立了相关性。 [外文原描述]： This International Standard specifies a method for determining and quantitatively expressing the folding endurance of photographic film. The method is based on the MIT folding-endurance tester described in annex B. It is an analytical test and is not intended to simulate practical use conditions. This International Standard is applicable to film with or without a gelatin backing. It may also be applied to either raw or processed film, although the flexibility level of a given film can be quite different after processing. Equipment similar to that described in this International Standard may be used provided that a correlation has been established between the results obtained using such equipment and the results obtained using the equipment described.
