本标准规定了一种音频测试磁带，用于调整以7.5 in/s（190.5 mm/s）磁带速度运行的四路磁带录像机的音频1记录（节目音频轨道）和音频2记录（提示轨道）的灵敏度和频率响应。磁带应用于按照ANSI/SMPTE 3操作的记录器上。SMPTE RP 102规定了音频2记录的工作电平和频率响应。

This standard specifies an audio frequency test tape to be used for adjusting the sensitivity and frequency response of audio 1 record (program audio track) and audio 2 record (cue track) of quadruplex video magnetic tape recorders operating at a tape speed of 7.5 in/s (190.5 mm/s). The tape shall be used on recorders operating in accordance with ANSI/SMPTE 3. The operating level and frequency response for audio 2 record are specified in SMPTE RP 102.
