The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 6022 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders. This second edition cancels and replaces the first edition (ISO 6022:1981 and ISO 8137:1986), which have been technically revised. BS ISO 6022:2006 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 26 07:01:07 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Introduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure within an enclosed circuit. One component of such systems is the fluid power cylinder. This is a device that converts power into linear mechanical force and motion. It consists of a movable element, i.e. a piston and piston rod, operating within a cylindrical bore.

NOTE This International Standard allows manufacturers of hydraulic equipment flexibility in the design of 25 MPa (250 bar) cylinders and does not restrict technical development; however, it does provide basic guidelines. 2 Normative references The following referenced documents are indispensable for the application of this document.

In these cases, flange ports in accordance with ISO 6162-1 or ISO 6164, as shown in this table, may not have sufficient pressure ratings. When flange ports with a higher pressure rating are needed, they can be selected from the higher pressure series in ISO 6162-2 and ISO 6164.
