本标准规定了16、35和70mm电影打印的屏幕亮度水平、亮度分布和投影光的光谱分布（色温），用于以每秒24帧的速度投影的剧院、阅览室和非热演示。本标准还规定了审查室的查看条件。这些规范的目的是实现投影印刷品的音阶、对比度和图像质量，使其达到生产过程中预期的质量。

This standard specifies the screen luminance level, luminance distribution, and spectral distribution (color temperature) of the projection light for theatrical, review- room, and nontheatrical presentation of 16-, 35-, and 70-mm motion-picture prints intended for projection at 24 frames per second. This standard also specifies review-room viewing conditions. It is the purpose of these specifications to achieve the tone scale, contrast, and pictorial quality of the projected print that will be of the quality intended during its production.
