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, 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

INTERNATIONAL STANDARD ISO 1680:2013(E)
Acoustics — Test code for the measurement of airborne
noise emitted by rotating electrical machines
1 Scope
This International Standard specifies all the information necessary to carry out efficiently and
under standardized conditions the determination, declaration, and verification of the noise emission
characteristics of rotating electrical machines. It specifies noise measurement methods that can be
used, and specifies the operating and mounting conditions required for the test.
Noise emission characteristics include the sound power level and emission sound pressure level. The
determination of these quantities is necessary:
— for comparing the noise emitted by machines;
— to enable manufacturers to declare the noise emitted; and
— for the purposes of noise control.
The use of this International Standard as a noise test code ensures the reproducibility of the
determination of the noise emission characteristics within specified limits determined by the grade of
accuracy of the basic noise measurement method used. Noise measurement methods allowed by this
International Stand
