The work of preparing International Standards is normally carried out through ISO technical committees. Eac
9、h 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 work. ISO collaborates closely with the Internatio

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

14、ment Part 2: Non-ducted indoor equipment 1 Scope This part of ISO 13261 specifies methods for the determination of sound power ratings of air-conditioning and air- source heat pump equipment to be used indoors. It is applicable to the sound power rating of the indoor sections of non-ducted, factory-
15、made, residential, commercial and industrial air-conditioning and air-source heat pump equipment, which are electrically driven with mechanical compression including free-delivery heat pumps, packaged-terminal air-conditioners and water-source heat pumps. This part of ISO 13261 includes both an octa
16、ve-band sound power level rating and a single-number A-weighted overall sound power level rating. This part of ISO 13261 does not apply to ducted indoor equipment, or to chillers, room fan coil units, products with variable speed compressors, or industrial process equipment. NOTE The terms “air-cond
17、itioner“ and “equipment“ are used to mean “air-conditioners and air-source heat pumps“ in this part of ISO 13261. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 13261. At the time of publication, the
18、editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 13261 are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.
