The UK participation in its preparation was entrusted to Technical Committee MCE/18, Fluid power systems and compon
3、ents, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promu
4、lgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the se

9、SO member bodies). 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, gov
10、ernmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance w
11、ith ISO procedures requiring at least 75% approval by the member bodies voting. International Standard ISO8137 was prepared by Technical Committee ISO/TC 131, Fluid power systems. Users should note that all International Standards undergo revision from time to time and that any reference made herein

13、ower is transmitted and controlled through a fluid (liquid or gas) under pressure within an enclosed circuit. One component of such systems is the fluid power cylinder. This is a device which converts power into linear mechanical force and motion. It consists of a movable element, i.e. a piston and
14、piston rod, operating within a cylindrical bore. 1 Scope and field of application This International Standard establishes port dimensions 1)for 250bar 2)(25 MPa) series cylinders as required for interchangeability of commonly used hydraulic cylinders. NOTEThis International Standard allows manufactu
15、rers of hydraulic equipment freedom in design of metric cylinders; it does not restrict technical development but provides basic guidelines. 2 References ISO 3320, Fluid power systems and components Cylinder bore and piston rod diameter Metric series.
