标准摘要
[中文适用范围]: 本标准规定了用于检查、调整和测量配音电影装置的声音再现通道的磁性声音测试片的基本技术特性。 它还规定了在 35 毫米、17.5 毫米和 16 毫米电影胶片上制作的磁性测试胶片的类型和技术特性。 本国际标准包括用于检查、调整和测量 a) 磁头间隙的倾斜角(方位角)的测试片; b) 多通道系统的输出电平平衡; c) 声音再现通道的频率响应; d) 薄膜速度的不均匀性(颤振)。 [外文原描述]: This International Standard specifies basic technical characteristics for the magnetic sound test films for checking, adjusting and measuring sound reproducing channels of dubbing motion-picture installations. It also specifies types and technical characteristics of magnetic test films made on 35 mm, 17,5 mm and 16 mm motion-picture films. This International Standard includes test films intended for the checking, adjusting and measuring of a) inclination angle (azimuth) of the magnetic head gaps; b) output level balance of multi-channel systems; c) frequency response of the sound reproduction channel; d) non-uniformity of film velocity (flutter).
