本标准仅限于测量满足以下标准的闭合导体中的平均稳态静压:必须传输液压动力；平均流速小于每秒82英尺；平均稳态静压小于70 Mpa（10000 psi）；内径大于3.0毫米（0.120英寸）；传感器没有与封闭的流体导体壁齐平安装，也不是其不可分割的一部分。

This standard is limited to the measurement of average steady-state static pressure in a closed conductor that meets the following criteria:must be transmitting hydraulic fluid power;average fluid velocities are less than 25 meters per second (82 ft/sec);average steady-state static pressure is less than 70 Mpa (10,000 psi);inside diameters are greater than 3.0 millimeters (0.120 in);sensor is not flush-mounted with, or an integral part of, the closed fluid conductor wall.
