20、al 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 has the right to be represented on that committee. Internatio
21、nal 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. The procedures used to develop this document and those intended
22、 for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the 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

27、 ST ANDARD ISO 9206:2016(E) Aerospace series Constant displacement hydraulic motors General specifications 1 Scope This International Standard establishes the general requirements for constant displacement hydraulic motors, suitable for use in aircraft hydraulic systems at pressures up to 35 000 kPa
28、 (5 000 psi). Primary and secondary function motors (see Clause 4) are covered in this International Standard; however, actuators with internal rotation angle limits and low-speed motors are not covered. This International Standard is to be used in conjunction with the detail specification that is p
