16、ord 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 for which a techni
17、cal 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) on all matters of e
18、lectrotechnical 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 are circulated to
19、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 responsible for i

BSISO169021:2003IS-20961 O1:(3002E) I SO 3002 All irhgts seredevr vIntroduction In hydraulic fluid power systems, power is transmitted and controlled through a liquid under pressure in a closed
22、circuit. Pumps are components that convert rotary mechanical power into fluid power. During the process of converting mechanical power into fluid power, airborne noise, fluid-borne noise and structure-borne noise are radiated from the pump. The airborne noise level of a hydraulic fluid power pump is
23、 an important consideration in component selection. ISO 4412-1 1describes a method of taking noise level measurements but requires a very specialized and costly test environment. The procedures described in this part of ISO 16902 do not require specialized and expensive test conditions but can be ex
24、pected to achieve “engineering” or “survey” levels of accuracy. The results should be sufficiently accurate so that comparisons can be made between pumps. It should be noted that sound power is physically a function of the test environment, and may in some cases differ from the sound power of the sa
