This International Standard specifies a selection of nominal pressures for hydraulic and pneumatic fluid power connectors and associated components.
NOTE 1 There may be a need to provide a selection of nominal pressures for connectors and associated com-ponents used in applications where the external pressure on the components is greater than the internal pressure, for example vacuum service. An International Standard that deals with this subject will be established in due course.
