BS ISO 9110-2:2020 PDF

What is ISO 9110-2 about?

ISO 9110 is a series on hydraulic fluid power. A hydraulic fluid power system has a pump driven by a prime mover (such as an electric motor or internal combustion engine) that converts mechanical energy into fluid energy. ISO 9110-2 establishes procedures for measuring the average steady-state pressure in a hydraulic fluid power conduit. ISO 9110-2 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. ISO 9110-2 provides the formulae for estimating the total uncertainty in each pressure measurement.
