9、tion 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 for which a technical committee has been established
10、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. In
11、ternational 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. Publi
12、cation 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 r

14、unting interface surfaces without electrical connector Part 2: Mounting interface surfaces with optional electrical connector BSISO154072:2003 iv Introduction In pneumatic fluid power systems, power is transmitted and controlled through gas under pressure within a circuit. The various devices for ga
15、s distribution and control can be either mounted directly on to the piping, or mounted on interface surfaces, allowing quicker dismantling and promoting equipment interchangeability. Pneumatic directional control valves of the five-port type, as used on mounting interface surfaces complying with the
16、 requirements of this part of ISO 15407, control the flow of compressed gas. When the valve is electrically operated, it may be desirable to use an electrical connector at the interface of the valve body and base. Users of pneumatic valves benefit when this electrical connector is standardized, allo
17、wing easy electrical connection interchangeability between valves produced by different manufacturers. Standardization of port and orifice identification, the result of control-mechanism actuation and a system of dimensional tolerances are provided to enhance mounting interchangeability of pneumatic
18、 control valves used on the mounting surfaces complying with the requirements of this part of ISO 15407.
