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

ISO 10140-1:2010(E)
Annex A
(normative)
Walls — Airborne sound insulation
A.1 Application
For walls and other partitions, ISO 10140-2 applies. This annex applies to lightweight twin leaf partitions, such
as those constructed of gypsum boards.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R is
given in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
A.2 Test element
The test opening for walls should be approximately 10 m .
A.3 Boundary and mounting conditions
The sound reduction index of lightweight twin leaf partitions (e.g. twin leaf gypsum board walls) is influenced
by the mounting conditions in the test opening of the laboratory. Important installation parameters include the
niche depth and the position of the partition in relation to the acoustic break in the test aperture.

Key
1 source room
2 receiving room
3 acoustic break of the laboratory
Figure A.1 — Example of the position of the test element
relative to the acoustic break of the laboratory
ISO 10140-1:2010(E)
To improve the reproducibility between laboratories and facilitate comparison of sound reduction indices for
different lightweight double walls, the twin leaf partition shall not be mounted across the acoustic break of the
laboratory, but on the same side of the break, as indicated in Figure A.1. The aperture should meet the
requirements in ISO 10140-2.
Other mounting conditions may be used but shall be fully described in the test report.
NOTE 1 Mounting the lightweight partition with one leaf on one side and the other leaf on the other side of the acoustic
break can result in higher values for the sound reduction index.
NOTE 2 Other mounting conditions can be suitable for certain types of twin leaf walls, for example walls for
semi-detached houses where the leaves are vibrationally uncoupled (for example on separate foundations). In such cases,
the wall leaves can be mounted on each side of the acoustic break.
A.4 Test and operating conditions
The test and operating conditions are given in ISO 10140-2.
A.5 Test report
The test report is given in ISO 10140-2.

ISO 10140-1:2010(E)
Annex B
(normative)
Doors — Airborne sound insulation
B.1 Application
This annex applies to internal and external doors (including door sets).
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R is
given in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
NOTE For a definition of door, see ISO 1804 and EN 12519.
B.2 Test element
For most doors, a test opening with an area of less than 10 m is needed. The area of the test element, S, is
the area of the opening in the filler wall required to accommodate the door.
B.3 Boundary and mounting conditions
The test opening for doors shall be arranged such that the lower edge is situated near to the level of the floor
of the test rooms and such that conditions in the building are reproduced. The door shall be installed for test
such that it can be opened and closed in the normal manner.
B.4 Test and operating conditions
The door shall be opened and closed at least five times immediately before testing.
B.5 Test report
The test report is given in ISO 10140-2.
ISO 10140-1:2010(E)
Annex C
(normative)
Windows — Airborne sound insulation
C.1 Application
This annex applies to windows.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R is
given in ISO 10140-2.
The general guidelines in the relevant clauses of ISO 10140-2 shall always be followed.
NOTE For a definition of window (terminology), see EN 12519.
C.2 Test element
The preferred dimensions of the test opening for a window are 1 250 mm ¥ 1 500 mm as for the specific
small-sized test opening described in ISO 10140-5, but variations from this size can be necessary in
recognition of national building practice. For windows, the test opening may be staggered as shown in
Figure 3 of ISO 10140-5:2010. In the case of a window assembly, dimensions may be chosen as
representative of the assembly used in practical circumstances. For windows, the area, S, is the area of the
opening in the filler wall required to accommodate the test element.
C.3 Boundary and mounting conditions
The installation of a window assembly shall be as similar as possible to the method which would be used in
practice. When the window is mounted in the test opening, the niches on both sides of the windows shall have
different depths, preferably in a ratio of about 2:1, unless this conflicts with the particular design of the window.
However, it is expected that results obtained with niche depths of different ratios would differ.
The gap between the window and the test opening (about 10 mm to 13 mm around the window when mounted
in the test opening) should be filled with absorbing material (for example mineral wool) and made airtight using
an elastic sealant on both sides or in accordance with the manufacturer's instructions.
If the test element is intended to be readily openable, it shall be installed for the test in such that a way it can
be opened and closed in the normal manner.
C.4 Test and operating conditions
C.4.1 Conditioning
The sound insulation of certain glazing systems or elements, especially those incorporating laminated glass,
can depend on the room temperature during the measurements. The temperature of both rooms used for
measuring the sound insulation should be (20 ± 3) °C. The test elements should be stored for 24 h at the test
temperature. In addition, it can be advantageous to make measurements at temperatures similar to those for
which the test element is designed.

ISO 10140-1:2010(E)
C.4.2 Operation
If the test element is intended to be openable, it shall be opened and closed at least five times immediately
before testing.
C.5 Test report
The test report is given in ISO 10140-2.
ISO 10140-1:2010(E)
Annex D
(normative)
Glazing — Airborne sound insulation
D.1 Application
This annex applies to glazing.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R is
given in ISO 10140-2.
The general guidelines in the relevant clauses of ISO 10140-2 shall always be followed.
NOTE For a definition of glass (terminology), see EN 12758.
D.2 Test element
The dimensions of the test opening for glazing shall be 1 250 mm × 1 500 mm with an allowable tolerance on
each dimension of ± 50 mm, preferably maintaining the same aspect ratio. For glazing, the test opening shall
be staggered on both sides and on the top by a distance of between 60 mm and 65 mm. The glazing shall be
mounted in the smaller opening as shown in Figure D.1. For glazing, the area, S, is the area of the opening in
the filler wall required to accommodate the test element.
The specific small-sized test opening described in ISO 10140-5:2010, Figure 3, fulfils these criteria, and a test
opening in accordance with ISO 10140-5:2010, 3.3.2, shall be used.
NOTE Details of the measurement conditions for glazing are prescribed in order to ensure the best possible
comparison between results obtained by different laboratories.
D.3 Boundary and mounting conditions
The glazing shall be installed into the test opening such that the niches on both sides of the pane have
different depths with a ratio of 2:1. A gap of about 10 mm shall remain between the pane and the reveal of the
test opening. This gap shall be filled with a type of putty, which shall be tested as described below. To fix the
glazing, two wooden beads (25 mm × 25 mm) shall be used (see Figure D.1). The space between the glazing
and the wooden beads shall be filled with putty about 5 mm thick. The beads shall cover not more than 15 mm
1)
and not less than 12 mm of the glass .
The putty used for filling the 10 mm gap between the perimeter of the glazing and the reveal of the test
opening, and the 5 mm gap between the glazing and the wooden beads shall be qualified by the following test
method. A single soda-lime/silica glass pane (float, density 2 500 kg/m, modulus of elasticity
E = 7 × 10 MPa) with a thickness of (10 ± 0,3) mm and dimensions of 1 230 mm × 1 480 mm shall be
mounted with this putty in accordance with Figure D.1. The airborne sound reduction index shall be
determined in one-third octave bands in the frequency range from 1 600 Hz to 3 150 Hz. The first
measurement shall begin not later than 1 h after mounting. The results shall be as follows, to within ± 2,0 dB:

1) This method of mounting and sealing a glass pane into the test opening is given as a practical, quick and reproducible
solution, although this is not the type of mounting in practice.

⎯ 2 000 Hz: R = 35,6 dB;
⎯ 2 500 Hz: R = 39,2 dB;
⎯ 3 150 Hz: R = 42,9 dB.
A second measurement shall be taken about 24 h later in order to make sure that no hardening process is
influencing the measurement. No systematic deviation average, ∆R (mean of the four ∆R values), greater than
0,5 dB is permitted.

NOTE Perennator TX 2001 S has been shown to fulfil these conditions .
The sound insulation measured for a type of glazing does not necessarily represent the sound insulation of a
window with that glazing. Preferably, therefore, the complete window should be measured as well to obtain
information on the sound insulation of the window and not only the glazing.

D.4 Test and operating conditions
The sound insulation of certain glazing systems or elements, especially those incorporating laminated glass,
can be dependent on the room temperature during the measurements. It is recommended that the sound
insulation measurements on such test elements be made at (20 ± 3) °C in both rooms. The test elements
should be stored for 24 h at the test temperature. In addition, it can be advantageous to make measurements
at temperatures similar to those for which the test element is designed.

Annex E
(normative)
Small technical elements — Airborne sound insulation
E.1 Application
This annex applies to small technical elements, for instance air intakes and other elements smaller than 1 m ,
such as profiles and shutter boxes.
The acoustic performance of the element is expressed in the element-normalized level difference, D per
n,e
unit, as defined in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
For small technical elements, the sound reduction index is less suitable as a descriptor because the area of
the test element is not normally well defined and the performance is not necessarily proportional to the area of
the test element. Therefore, the performance is expressed as a normalized level difference for a specific unit.
Furthermore, due to the small dimensions and mounting conditions, the direct environment around the test
element and nearby objects can have a large influence on the results and should therefore be carefully
specified.
E.2 Test element
E.2.1 General
Ensure that the test element is installed in a manner representative of field practice using normal connections
and sealing conditions at the perimeter and at joints within the unit.
The building elements are small and, in combination with the spatial variations of the sound fields, this leads
to significant dependency on their position; it is therefore recommended more than one position of the test
element be used (see E.2.2).
In order to achieve a realistic wall thickness around the element, it may be practical or necessary to either
increase or decrease the thickness of the partition wall in the area around the element (see E.2.3 and E.2.4).
When a small building unit is mounted near one or more reflecting planes, the sound transmission can differ
appreciably from that obtained when the unit is mounted through a partition, but away from any adjoining room
surface. Therefore, mount the equipment selected for testing through the partition in positions representative
of normal usage. If natural corners or edges are not available in the test opening, it is essential to simulate
such mounting conditions by attaching reflective panels at right angles to the partition wall, as described in
E.2.5.
E.2.2 Number of positions
Three positions should be used for the mounting of the test element in the partition wall. These positions shall
either be simulated, as described in E.2.5, or they shall be located at least 1,2 m from each other.
A dependency on position also occurs for apparently equivalent corners; this makes it necessary to use more
than one corner.
ISO 10140-1:2010(E)
NOTE When simulating corner or edge positions by attaching reflective panels, it is possible to achieve the
necessary position averaging by changing the locations and orientations of the reflective panels while the test element
stays in the same position.
E.2.3 Local increase of wall thickness
Instead of changing the thickness of the complete partition wall, simulate various wall thicknesses by adding
extra panels with a mass per unit area of more than 10 kg/m to the original partition construction. The edges
of such additional panels shall be at least 0,5 m from any part of the test element.
E.2.4 Local decrease of wall thickness
If a thick partition wall is needed to achieve a sufficiently high flanking transmission loss, create a realistic wall
thickness around the test device by locally reducing the thickness using panels. This shall be done in
accordance with Figure E.1.

The following relations shall hold:
a) l > 0,6 m;
b) l > 0,1 m; if l > 0,5 m in every direction, no smooth transition of thickness is necessary;
2 2
c) α < 30°.
E.2.5 Central, corner and edge positions
E.2.5.1 Equipment used away from walls
Install equipment mounted through a partition but normally located away from an adjoining wall, floor or ceiling
in such a manner that no part is within 1,00 m of a surface at right angles to the mounting surface; 0,85 m is
sufficient, if several elements are tested at the same time.
E.2.5.2 Equipment used near an edge
Locate equipment mounted through a partition, and normally located near an adjoining wall, floor or ceiling,
and away from a corner, at least 1,00 m (0,85 m if several elements are tested at the same time) from the
12 © ISO 2010 – All rights reserved

ISO 10140-1:2010(E)
nearest wall not being a part of the edge. Unless otherwise specified by the manufacturer, locate the edge of
the equipment 0,1 m from the edge of the wall.
E.2.5.3 Equipment used near a corner
Locate equipment mounted through a partition and normally located near a corner at a distance from the
corner which should be representative of typical use, as recommended by the manufacturer.
E.2.5.4 Simulation of corner or edge positions
The simulation of a corner is shown in Figure E.2. To simulate an edge, it is sufficient to use only one panel,
the dimensions of which shall be at least 1,2 m × 2,4 m. The panels shall not be mounted parallel to the
boundary surfaces of the room. If it is necessary to use additional panels in both the source room and the
receiving room, ensure that the locations and orientations of the panels are the same in both rooms.
The mass per unit area of the panels shall exceed 7 kg/m . Above 100 Hz, the sound absorption coefficient
shall be less than 0,1.
Seal the connections between the panels and the partition wall with, for example, a heavy adhesive tape. As
the mounting of additional panels to the partition wall can influence its transmission characteristics, include the
various panel arrangements in the measurements of the flanking transmission.

E.3 Boundary and mounting conditions
E.3.1 Transfer air devices
Install the test elements in a manner representative of field practice and in typical locations with respect to the
room surfaces, as given in the installation rules above. Mount transfer air devices which are normally mounted
near an adjoining ceiling in a position close to a reflective surface at right angles to the partition, but at least
ISO 10140-1:2010(E)
1,00 m (0,85 m if several elements are tested at the same time) from any corner. The distance between the
closest part of the device and the adjoining surface shall be 0,1 m. Accessories that are normally used shall
be included. Position and fix these accessories in accordance with the manufacturer's instructions.
For devices which can be used in several different positions, carry out measurements with at least an edge
present in both rooms.
If the device is continuously adjustable to various wall thicknesses, ensure that the tests comprise at least the
two extreme wall thicknesses for which the device is stated to be suitable.
E.3.2 Electrical raceways
Install the test element in a manner representative of field practice and in typical locations with respect to the
room surfaces. Mount raceways which are normally mounted directly on walls on a reflective surface at right
angles to the partition and according to the manufacturer's directions. Include accessories normally used.
Install these accessories according to the manufacturer's instructions.
Install the test element with an exposed continuous duct length of at least 2 m, both in the source and in the
receiver room. Provide the exposed duct ends with standard end covers.
Soundproofing accessories used in installations through partition walls are often available in raceways. To test
practical sealing and insulating properties of such soundproofing accessories, it is recommended that the
raceway be filled to its rated capacity with cables.
NOTE The acoustic performance can vary with the number of cables.
If the edge mounting is simulated with additional panels, ensure that the panel length is at least as long as the
duct length.
E.4 Test and operating conditions
For transfer air devices, if the device is provided with some air-flow control, ensure that the equipment is
operated in a specified manner typical of normal usage. The fully open condition should be included amongst
the tests.
E.5 Test report
The test report is given in ISO 10140-2. The following additional information shall also be reported:
a) a detailed description of the corners or edges used, being normally available or simulated;
b) a detailed description of the methods used to increase or decrease the wall thickness in order to install
the test element.

(normative)
Acoustical linings — Improvement of airborne sound insulation
G.1 Application
This annex applies to acoustical linings on walls and floors.
The quantity determined is the sound reduction improvement index, ∆R, in decibels, which is defined as the
difference between the sound reduction indices of the basic element with and without the lining for each one-
third octave band:
∆=RR −R
with without
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
NOTE 1 The sound reduction improvement of a lining can be different for direct and flanking sound transmission as
well as for airborne and impact sound excitation. The method described in this part of ISO 10140 yields the sound
reduction improvement for direct airborne sound transmission.
NOTE 2 This annex does not deal with the sound reduction improvement by linings on flexible lightweight structures,
such as timber frame floors or double-leaf gypsum board walls.
NOTE 3 The sound reduction index of walls/floors and acoustical linings are characterized separately for the
comparison of products. In addition, the European calculation model for the acoustic performance of buildings from the
performance of elements distinguishes the sound reduction index of a wall (or floor) and the improvement of the sound
reduction index by an additional lining. The laboratory measurement of this sound reduction improvement is the subject of
this annex.
