标准摘要
[中文适用范围]： 适用于用于连续色调或绘画摄影的所有传统卤化银接触纸和放大纸。 该方法基于曝光和处理样本，对所得图像进行密度测量以产生感光曲线，根据该曲线进行测量并用于确定 ISO 速度和 ISO 范围值。 附录 A 至 C 阐述了纸张范围与底片有效密度范围、对数曝光范围与对比度、对数曝光范围与平均梯度之间的关系。 [外文原描述]： Pertains to all conventional silver-halide contact and enlarging papers used for continuous-tone or pictorial photography. The method is based on exposing and processing samples, performing density measurements from the resultant image to produce a sensitometric curve from which measurements are taken and used to determine ISO speed and ISO range values. Annexes A to C deal with the relationships between the paper range and the effective density range of the negative, log exposure range and contrast, and log exposure range and average gradient.
