标准摘要
[中文适用范围]： 本部分 ISO 5 规定了测量 ISO 5 标准漫射透射密度和 f/4.5 及 f/1.6 投影透射密度的几何条件。ISO 5 标准漫射密度主要适用于在透射照明器或观看箱上观看、用于接触印刷或采用漫射照明系统投影的摄影图像测量。ISO 5 标准投影密度主要适用于采用光学聚光器系统投影的摄影图像测量。虽然主要 intended 用于摄影图像的测量，但本部分 ISO 5 规定的密度测量方法也常用于光学滤光片和其他透明材料的测量。 [外文原描述]： ISO 5-2:2009 specifies the geometric conditions for measuring ISO 5 standard diffuse and ƒ /4,5 and ƒ /1,6 projection transmittance densities. ISO 5 standard diffuse density is primarily applicable to measurements of photographic images to be viewed on a transparency illuminator, or viewing box, to be contact printed, or to be projected with a system employing diffuse illumination. ISO 5 standard projection density is primarily applicable to measurements of photographic images to be projected with systems employing optical condensers. Although primarily intended for the measurement of photographic images, the densitometric methods specified in ISO 5-2:2009 are often applied to optical filters and other transparent materials.
