This International Standard gives guidance for the use of a series of nine International Standards describing
various methods for determining the sound power levels from all types of machinery and equipment. It provides:
brief summaries of these basic International Standards;
guidance on the selection of one or more of these standards which are appropriate to any particular type (see
clause 5 and annex D). The guidance given applies only to airborne sound. It is for use in the preparation of
noise test codes (see ISO 12001) and also in noise testing where no specific noise test code exists.
This International Standard is not intended to replace any of the details of, or add any additional requirements to,
the individual test methods in the other basic standards referred to.
These basic standards specify the acoustical requirements for measurements appropriate for different test
environments and accuracies.
It is important that specific test codes for various types of machinery and equipment be established and used in
accordance with the requirements of these basic International Standards. Such standardized noise test codes will
recommend the basic International Standard(s) to be used and will give detailed requirements on mounting and
operating conditions for a particular family to which the machine under test belongs.
If no specific noise test code exists for a particular type of machinery, this International Standard is of use for the
choice of the most suitable of the basic standards. In all cases, the mounting and operating conditions of the
machine under test should be in accordance with the general principles given in the basic standards.
NOTE Two quantities which complement each other can be used to describe the sound emission of machinery or
equipment. One is the emission sound pressure level at a specified position and the other is the sound power level. The
