It supersedes BS ISO 6020-1:1998 and BS ISO 8135:1999, which are withdrawn. The UK participation in its preparation was entrusted by Technical Committee MCE/18, Fluid power systems and components, to Panel MCE/18/-/3, Cylinders. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract.

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 6020-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders. This third edition cancels and replaces the second edition (ISO 6020-1:1998) and ISO 8135:1999, which have been technically revised. ISO 6020 consists of the following parts, under the general title Hydraulic fluid power Mounting dimensions for single rod cylinders, 16 MPa (160 bar) series: Part 1: Medium series Part 2: Compact series Part 3: Compact series with bores from 250 mm to 500 mm BS ISO 6020-1:2007 Licensed Copy: London South Bank University, London South Bank University, Fri Nov 16 07:28:01 GMT+00:00 2007, Uncontrolled Copy, (c) BSI v 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.

The medium series dimensions are applicable to round head cylinders with bores from 25 mm to 200 mm and to both round and square head cylinders with bores larger than 200 mm, thus allowing a wider range of applications. NOTE This part of ISO 6020 allows manufacturers of hydraulic equipment flexibility in the design of 16 MPa (160 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.
