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 10140-4 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
acoustics.
This second edition of ISO 10140-4 cancels and replaces ISO 10140-4:2010, which has been technically
revised.
ISO 10140 consists of the following parts, under the general title Acoustics — Laboratory measurement of
sound insulation of building elements:
 Part 1: Application rules for specific products
 Part 2: Measurement of airborne sound insulation
 Part 3: Measurement of impact sound insulation
 Part 4: Measurement procedures and requirements
 Part 5: Requirements for test facilities and equipment

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 preparation, mounting, operating and t
