成像材料 摄影胶片和相纸 弯曲的测定

[中文适用范围]： 本国际标准规定了测定和定量表达片状、卷状或条状的未处理和处理过的摄影胶片和相纸的卷曲特性的方法。 它规定了三种测量方法：方法 A 涉及测定样本处于垂直位置时的卷曲度，方法 B 和 C 涉及样本处于水平位置时的卷曲度。 由于样本配置和尺寸的差异，三种方法的值不具有可比性。 这些方法不适用于确定冲洗或干燥期间照相材料的卷曲特性。 [外文原描述]： This International Standard specifies methods for determining and quantitatively expressing the curl characteristics of unprocessed and processed photographic film and paper in sheet, roll or strip formats. It specifies three measuring methods: method A involves the determination of curl when the specimen is held in a vertical position, methods B and C with the specimen in a horizontal position. The values for the three methods are not comparable because of the differences in specimen configuration and size. These methods are not intended for use in determining the curl characteristics of photographic materials during processing or drying.
