The work of preparing Internati
12、onal Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a t echnical committee has beenestablished has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with IS
13、O, also take part in the work. ISO collaborates closelywith 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 comm
14、ittees is to prepare International Standards. Draft International Standardsadopted by the technical committees are ci rculated to the member bodies for voting. Publ ication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the
15、possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying an y or all such patent rights. ISO 4395 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 3, Cylinders . This second editi
16、on cancels and replaces the first edition (ISO 4 395:1978), which has been technically revised.BS ISO 4395:2009ISO 4395:2009 (E) BSI 2010 vIntroduction In fluid power systems, power is transmitted and controlled through a liquid (for hydraulics) or a gas (forpneumatics) under pressure within an encl
17、osed circuit.One component of such systems is the cylinder. This is a device that converts power into linear mechanical force and motion. It consists of a moveable element, i.e. a piston and piston rod, operating within a cylindricalbore. BS ISO 4395:2009ISO 4395:2009 (E) BSI 2010 INTERNATIONAL STAN
