ISO 10140-3:2021(E)
Introduction
ISO 10140 (all parts) concerns laboratory measurement of the sound insulation of building elements
(see Table 1).
ISO 10140-1 specifies the application rules for specific elements and products, including specific
requirements for the preparation and mounting of the test elements, and for the operating and test
conditions. ISO 10140-2 and this document contain the general procedures for airborne and impact
sound insulation measurements, respectively, and refer to ISO 10140-4 and ISO 10140-5 where
appropriate. For elements and products without a specific application rule described in ISO 10140-1, it is
possible to apply ISO 10140-2 and this document. ISO 10140-4 contains basic measurement techniques
and processes. ISO 10140-5 contains requirements for test facilities and equipment. For the structure of
ISO 10140 (all parts), see Table 1.
ISO 10140 (all parts) was developed to improve the layout for laboratory measurements, ensure
consistency and simplify future changes and additions regarding mounting conditions of test elements
in laboratory and field measurements. ISO 10140 (all parts) aims at presenting a well-written and
arranged format for laboratory measurements.
ISO 10140-1 is planned to be updated with application rules for other products.

INTERNATIONAL STANDARD ISO 10140-3:2021(E)
Acoustics — Laboratory measurement of sound insulation
of building elements —
Part 3:
Measurement of impact sound insulation
1 Scope
This document specifies laboratory methods for measuring the impact sound insulation of floor
assemblies.
The test results can be used to compare the sound insulation properties of building elements, classify
elements according to their sound insulation capabilities, help design building products which require
certain acoustic properties and estimate the in situ performance in complete buildings.
The measurements are performed in laboratory test facilities in which sound transmission via flanking
paths is suppressed. The results of measurements made in accordance with this document are not
applicable directly to the field situation without accounting for other factors affecting sound insulation,
such as flanking transmission, boundary conditions, and loss factor.
A test method is specified that uses the standard tapping machine (see ISO 10140-5:2021, Annex E)
to simulate impact sources like human footsteps when a person is wearing shoes. Alternative test
methods, using a modified tapping machine or a heavy/soft impact source (see ISO 10140-5:2021,
Annex F) to simulate impact sources with strong low frequency components, such as human footsteps
(bare feet) or children jumping, are also specified.
This document is applicable to all types of floors (whether heavyweight or lightweight) with all types of
floor coverings. The test methods apply only to laboratory measurements.

Note 1 to entry: L is expressed in decibels.

measured reverberation time and the volume of the receiving room as specified in ISO 10140-4.
4 Facilities and equipment
Laboratory test facilities shall comply with the requirements of ISO 10140-5:2021, Annex A.
The tapping machine shall meet the requirements given in ISO 10140-5:2021, Annex E.
Requirements for equipment used to measure the sound level, and for calibration of that equipment, are
specified in ISO 10140-5.
NOTE Alternative methods using a modified tapping machine or a standard heavy/soft impact source can
provide information suitable for assessing the impact sound insulation of a floor or a floor covering against
common impact sources, for instance a person walking without shoes or a child jumping. Procedures for
measurements using a heavy/soft impact source are given in Annex A. Requirements for alternate impact sources
are given in ISO 10140-5:2021, Annex F.
