The work of preparing International Standards is no
10、rmally 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
11、 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular t
12、he different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this doc

17、r. 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.

19、nterchangeability of these commonly used hydraulic cylinders.NOTE 1 This International Standard is intended to provide basic guidelines while allowing manufacturers of hydraulic equipment flexibility in the design of cylinders and not restricting technical development.NOTE 2 The dimensions of these
20、cylinders are most likely to require a minimum of space for mounting.NOTE 3 1 bar = 0,1 MPa = 105Pa; 1 MPa = 1 N/mm2.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
