24、0 03:06:26 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committee
25、s. 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 organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inter
26、national Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International St
27、andards 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 to the possibility that some of the elements of this document may be the sub
28、ject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10848-3 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 126, Acoustic properties of building elements and of buildings, in collaboration with Techni
29、cal Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building acoustics, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). ISO 10848 consists of the following parts, under the general title Acoustics Laboratory measurement of the flanking transmissio
30、n of airborne and impact sound between adjoining rooms: Part 1: Frame document Part 2: Application to light elements when the junction has a small influence Part 3: Application to light elements when the junction has a substantial influence The following part is under preparation: Part 4: Applicatio
31、n to all other cases EN ISO 10848-3:2006 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 03:06:26 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 Acoustics Laboratory measurement of the flanking transmission of airborne and impact sound between adjoining rooms Part 3: Application to light elemen
32、ts when the junction has a substantial influence 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 measured quantities can be used to compare different products,
33、or to express a requirement, or as input data for prediction methods, such as EN 12354-1 and EN 12354-2. This part of ISO 10848 is specifically referred to in ISO 10848-1:2006, 4.4, as being a supporting part to the frame document. This part of ISO 10848 applies to structurally connected light eleme
34、nts forming a T or X junction. A light element is defined in ISO 10848-1:2006, Clause 3. The relevant quantity to be measured is selected according to ISO 10848-1:2006, 4.4. The performance of the building components is expressed either as an overall quantity for the combination of elements and junc
35、tion (such as Dn,f and/or Ln,f) or as the vibration reduction index Kij of a junction. Dn,f and Ln,f depend on the actual dimensions of the elements, while Kij is in principle an invariant quantity. For general application of the test results, Dn,f and Ln,f are the relevant quantities to measure for
36、 lightweight, well-damped types of elements (for example, timber or metal framed stud walls or wooden floors on beams), where the actual situation has no real influence on the sound reduction index and damping of the elements. If the acoustical properties of the elements are substantially influenced
37、 by the actual situation, Kij is the relevant quantity to measure. 2 Normative references The following referenced documents are indispensable for the application of this document.

48、ction length between elements i and j, in metres; ai, aj are the equivalent absorption lengths of elements i and j, in metres. NOTE 1 The equivalent absorption length depends on the structural reverberation time as defined in ISO 10848-1:2006, 3.8. For lightweight, well-damped types of elements wher
49、e the actual situation has no real influence on the sound reduction index and damping of an element, aj is taken as numerically equal to the surface area Sj of the element, aj = Sj/l0, where the reference length l0 = 1 m. NOTE 2 The vibration reduction index is related to the vibrational power transmission over a junction between structural elements, normalized in order to make it an invariant quantity. 4 Measuring equipment The equipment s
