本规程规定了通过在0.9 m/s（180 ft/min）速度下运行的胶片处理系统运输35 mm电影胶片所需的胶片张力，同时将导致胶片损坏的条件降至最低。本规程还推荐了测试薄膜张力的方法。

This practice specifies the film tension needed to transport 35-mm motion-picture film through a film-handling system operating under 0.9 m/s (180 ft/min) while minimizing conditions that contribute to film damage.This practice also recommends methods for testing film tension.
