27、ndards 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. International or

28、ganizations, 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. International Standards are drafted in accordance with the rules give

29、n 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 the member bodies for voting. Publication as an International Standard requires approval by at least 7

30、5 % 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.

33、oise control in offices and workrooms by means of acoustical screens 1S c o p e This International Standard deals with the effectiveness of acoustical screens. It specifies the acoustical and operational requirements to be agreed upon between the supplier or manufacturer and the user of acoustical s

34、creens. This International Standard is applicable to the following types of acoustical screens: a) free-standing acoustical screens for offices, service areas, exhibition areas, and similar rooms; b) acoustical screens integrated in the furniture of such rooms; c) portable and removable acoustical s

35、creens for workshops; d) fixed room partitions with more than of the connecting area open and acoustically untreated. Walls of partial acoustic enclosures and cabins which, together with the room boundary surfaces, also partition a room and provide more than open and acoustically untreated area, are

36、 also treated as acoustical screens. NOTE Guidance on complete acoustic enclosures is given in ISO 15667. This International Standard is not applicable to cabinet walls and similar multi-layer walls whose thickness exceeds , nor to banners and other types of suspended baffles. 2 Normative references
