1.范围1。1本标准规定了机器可读的120孔重复孔的位置和尺寸 身份证号码。这些数字旨在成为潜影密钥的机器可读版本 数字本标准还规定了用于这些机器可读数字的编码格式，如下所示: 以及扫描区域和扫描仪的光谱特征。1.2本标准还规定了人类可读标识（图例）的位置、尺寸和内容 用于原版摄影或中间印刷的65毫米电影胶片的编号 还包括1.1中所述的机器可读密钥号。这些数字通常是 在生产时暴露在胶片上。1.3本标准进一步规定了可用于可选制造商特定胶片类型的区域 身份信息。1.4本标准还规定了胶片上胶片制造商不会暴露的区域，因此 使其可用于客户数据记录。1.5最后，本标准规定了可选的框架线索引标记。

1 Scope1.1 This standard specifies the position and dimensions of 120 perforation repeat machine-readable identification numbers. These numbers are intended to be a machine-readable version of the latent image key number. This standard also specifies the encoding format to be used for these machine-readable numbers, as well as the area scanned and the spectral characteristics of the scanner.1.2 This standard also specifies the position, dimensions, and content of human-readable identification (key) numbers for use on 65-mm motion-picture films intended for original photography or intermediate printing which also include the machine-readable key number described in 1.1. These numbers normally will be exposed onto the film at the time of manufacture.1.3 This standard further specifies an area that may be used for optional manufacturer-specific film-type identification information.1.4 This standard also specifies an area on the film which is not to be exposed by the film manufacturer, thus leaving it available for customer data recording.1.5 Finally, this standard specifies optional frameline index marks.
