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).

Introduction
An assessment of uncertainties that is comprehensible and close to reality is indispensable for many
questions in building acoustics. Whether a requirement is met, a laboratory delivers correct results
or the acoustic properties of a product are better than the same properties of some other product
can be decided only by adequately assessing the uncertainties associated with the quantities under
consideration.
Uncertainties should preferably be determined following the principles of ISO/IEC Guide 98-3. This Guide
specifies a detailed procedure for the uncertainty evaluation that is based upon a complete mathematical
model of the measurement procedure. At the current knowledge, it seems to be impossible to formulate
these models for the different quantities in building acoustics. Therefore, only the principles of such an
uncertainty assessment are explained.
To come to uncertainties all the same, the concept of reproducibility and repeatability is incorporated
which is the traditional way of uncertainty determination in building acoustics. This con
