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 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 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 rules 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 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 subject 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 Technical
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 transmission 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:

INTERNATIONAL STANDARD ISO 10848-3:2006(E)

Acoustics — Laboratory measurement of the flanking
transmission of airborne and impact sound between adjoining
rooms —
Part 3:
Application to light elements 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, 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 elements 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 junction
(such as D and/or L ) or as the vibration reduction index K of a junction. D and L depend on the actual
n,f n,f ij n,f n,f
dimensions of the elements, while K is in principle an invariant quantity.
ij
For general application of the test results, D and L are the relevant quantities to measure for lightweight,
n,f n,f
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 by the actual situation, K is the relevant
ij
quantity to measure.
