24、s 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 organiz
25、ations, 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 given in
26、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 75 % o
27、f 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 Standardiz
28、ation (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 (Vienna Agreemen

31、 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 building components. The performance of the building components is expressed either as an overall quantity for the combination
32、of elements and junction (such as Dn,fand/or Ln,f) or as the vibration reduction index Kijof a junction. This part of ISO 10848 contains definitions, general requirements for test specimens and test rooms, and measurement methods. Guidelines are given for the selection of the quantity to be measured
33、 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. The quantities characterizing the flanking transmission can be used to compare different products, or to express a requireme
34、nt, 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 of this document.
