标准摘要
[中文适用范围]： 本文件建立了测量液压流体动力管道中平均稳态压力的程序。 适用于内径大于3mm、传输平均液速小于25m/s、平均稳态静压小于70MPa的液压流体动力的封闭管道中平均稳态压力的测量。 它不适用于与封闭流体导管壁齐平安装或作为其组成部分的传感器。 它提供了用于估计给定压力测量的总不确定度的公式。 [外文原描述]： This document establishes procedures for measuring the average steady-state pressure in a hydraulic fluid power conduit. It is applicable to the measurement of average steady-state pressure in closed conduits with inside diameters greater than 3 mm, transmitting hydraulic fluid power with average fluid velocities less than 25 m/s and average steady-state static pressures less than 70 MPa. It is not applicable to sensors which are flush mounted with, or an integral part of, the closed fluid conduit wall. It provides the formulae for estimating the total uncertainty in a given pressure measurement.
