The work of preparing International Standards is normally
9、 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 the w
10、ork. ISO collaborates closely with 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 3. The main task of technical committees is to prepare Int
11、ernational Standards. Draft International Standards adopted by the technical committees 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
12、the elements of this part of ISO 4392 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4392-1 was prepared by Technical Committee ISO/TC 131, Fluid power systems, Subcommittee SC 8, Product testing. This third edition cancels a
13、nd replaces the second edition (ISO 4392-1:1989), of which it constitutes a minor revision. ISO 4392 consists of the following parts, under the general title Hydraulic fluid power Determination of characteristics of motors: Part 1: At constant low speed and constant pressure Part 2: Startability Par

16、pressure 1 Scope This part of ISO 4392 describes a method of determining the low speed characteristics of positive displacement rotary fluid power motors, of either fixed or variable displacement types. The method involves testing at slow speeds which may generate frequencies having a significant in
17、fluence upon the steady continuous torque output of the motor and affect the system to which the motor would be connected. The accuracy of measurement is divided into three classes, A, B and C, which are explained in annex A. 2 Normative references The following normative documents contain provision
18、s which, through reference in this text, constitute provisions of this part of ISO 4392. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 4392 are encouraged to investigate the possibilit
19、y of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
