22、tion of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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 committ
23、ee. International organizations, governmental and non-governmental, in aison with ISO, also take part in the work. IS0 collaborates closely with the Interna onal Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Interna onal Standards are drafted in accordance wit
24、h the rules given in the ISOIIEC Directives, Part 3. 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 t

Annexes A and B of this International Standard are for information only. iv EN IS0 15667:2000 Introduction Acoustic enclosures and cabins provide a reduction of airborne sound on the propagation path from the machine (or a set of machines) to nearby work stations or to the environment. This
27、 International Standard describes criteria which determine the acoustic performance of enclosures and cabins with consideration of operational aspects. V EN IS0 15667:ZOOO EN IS0 16667:2000 Acoustics - Guidelines for noise control by enclosures and cabins 1 Scope This International Standard deals wi
28、th the performance of enclosures and cabins designed for noise control. outlines the acoustical and operational requirements which are to be agreed upon between the supplier or manufacturer and the user of such enclosures and cabins. This International Standard is applicable to two types of acoustic
29、 enclosures and cabins, as follows. a) Cabins for noise protection of operators: free-standing cabins and cabins attached to machines (e.g. vehicles, cranes). b) Free-standing enclosures covering or housing machines: enclosures with a fraction of acoustically untreated open area of less than 10 %of
30、the total surface are the main subject of this International Standard. In this International Standard, emphasis is put on ghtweight constructions. However, thick, massive structures as, for example, brick wa s, are not excluded. Enclosures and cabins with more than 10 % open and untreated area belon
31、g to the category of partial enclosures. They are not the subject of this International Standard. A th d type of enclosure, integrated enclosures which form a part of the machine and are f mly attached to it, is not the subject of this International Standard. 2 Normative references The following nor
32、mative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standar
