What is ISO 4399 - Fluid power systems and components about?
ISO 4399 discusses fluid power systems and components. Fluid power systems perform work by a pressurized fluid bearing directly on a piston in a cylinder or in a fluid motor. ISO 4399 specifies a selection of nominal pressures for hydraulic and pneumatic fluid power connectors and associated components.
There can be a need to provide a selection of nominal pressures for connectors and associated components used in applications where the external pressure on the components is greater than the internal pressure, for example, vacuum service.
Who is ISO 4399 - Fluid power systems and components for ?
ISO 4399 on fluid power systems and components is useful for:
Fluid power component manufacturers
Fluid power equipment manufacturers
Heavy earthmoving machine manufacturers
Design engineers
Quality control personnel
Why should you use ISO 4399 - Fluid power systems and components ?
Within a fluid power system, cylinders, and motors (also called actuators) do the desired work. Control components such as valves regulate the system. In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. Components may be connected through their ports by connections (fittings) and conduits. Tubes are rigid conduits. ISO 4399 defines the nominal pressure value that is assigned to a component, piping...
