26、al 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 technical committee has been established has the right to be represented on that committee. Internatio
27、nal 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 electrotechnical standardization. International Standards are drafted in accordance with the rule
28、s 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 the member bodies for voting. Publication as an International Standard requires approval by at l
29、east 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 identifying any or all such patent rights. ISO 10848-1 was prepared by the European Committee for
30、 Standardization (CEN) Technical Committee CEN/TC 126, Acoustic properties of building elements and of buildings, in collaboration with Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement on technical cooperation between ISO and CEN (Vien
31、na Agreement).

33、s Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms Part 1: Frame document 1 Scope ISO 10848 specifies measurement methods to be performed in a laboratory test facility in order to characterize the flanking transmission of one or several buildin
34、g components. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as Dn,f and/or Ln,f ) or as the vibration reduction index Kij of a junction. This part of ISO 10848 contains definitions, general requirements for te
35、st specimens and test rooms, and measurement methods. Guidelines are given for the selection of the quantity to be measured depending on the junction and the types of building elements involved. Other parts of ISO 10848 specify the application for different types of junction and building elements. T
36、he quantities characterizing the flanking transmission can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as EN 12354-1 and EN 12354-2. 2 Normative references The following referenced documents are indispensable for the application o
