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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: w w w . i s o .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This second edition cancels and replaces the first edition (ISO 10848-2:2006), which has been
technically revised. It also incorporates the Technical Corrigendum ISO 10848-2:2006/Cor. 1:2007. The
main change is that the normalized flanking equipment sound pressure level has been introduced and
it has been indicated that this document applies to Type B elements.
A list of all the parts in the ISO 10848 series can be found on the ISO website.

Acoustics — Laboratory and field measurement of flanking

equipment sound between adjoining rooms —
Part 2:
Application to Type B elements when the junction has a
small influence
1  Scope
ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one
or several building components. This document considers only laboratory measurements.
The measured quantities can be used to compare different products, or to express a requirement, or
as input data for prediction methods, such as ISO 12354-1 and ISO 12354-2. However, the measured
quantities D , L and L only represent the performance with the dimensions for the test specimens
n,f n,f ne0,f
described in this document.
This document is referred to in ISO 10848-1:2017, 4.5 as being a supporting part of the frame document.
It applies to Type B elements as defined in ISO 10848-1, such as suspended ceilings, access floors,
light uninterrupted façades or floating floors. The transmission from one room to another can occur
simultaneously through the test element and via the plenum (if any). For measurements made according
to this document, the total sound transmission is determined and it is not possible to separate the two
kinds of transmission.

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
