9、6263:2013(E) Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject
10、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) o
11、n 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
12、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

Typical components found in such systems are hydraulic valves. The devices control flow
15、direction, pressure, or flow rate of liquids in the enclosed circuit. ISO 2013 All rights reserved vBS ISO 6263:2013BS ISO 6263:2013Hydraulic fluid power Compensated flow-control valves Mounting surfaces 1 Scope This International Standard specifies the dimensions and other data relating to surfaces
16、 on which hydraulic compensated flow-control valves are mounted in order to ensure interchangeability. It applies to mounting surfaces for hydraulic compensated flow-control valves which represent current practice; they are generally applicable to industrial equipment. 2 Normative references The fol
