成像材料.已冲洗过的摄影胶片.测定耐划伤性的方法

[中文适用范围]： 本国际标准适用于评价干燥、冲洗过的照相胶片的耐划伤性。 它规定了两种用于评估乳液或基底面的耐刮擦性的测试方法。 这两种测试方法通常会给出可比较的结果。 它提供了在受控条件下进行的经验实验室测试，但不一定预测薄膜在任何特定商业机器中的实际耐刮擦性。 方法 A（参见第 3 条）给出了产生划痕的最小负载要求的测量方法，需要不太复杂的评估设备，并且对样本光学条件的要求也不太严格。 方法 B（参见第 4 条）提供了对各种触针负载产生的雾度的测量，是对材料划痕特性的更完整的测量，并且是首选方法。 [外文原描述]： ISO 18922:2002 is applicable to evaluating the scratch resistance of dry, processed photographic film. It specifies two test methods for evaluating the scratch resistance on either the emulsion or the base side. The two test methods usually give comparable results. It provides empirical laboratory tests made under controlled conditions, but does not necessarily predict the actual scratch resistance of a film in any particular commercial machine. Method A gives a measure of the minimum load requirement to produce a scratch, requires less elaborate evaluation equipment and is less stringent in its requirements of the optical condition of the specimens. Method B provides a measurement of haze produced by various stylus loads, is a more complete measure of scratch characteristics of a material and is the preferred method.
