Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
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.
International Standard IS0 11202 was prepared by Technica I Committee
ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.

Introduction
0.1 This International Standard specifies a method for measuring the
emission sound pressure levels at a work station and at other specified
positions in the vicinity of a machine or piece of equipment. The method
specified in this International Standard follows the method specified in
IS0 11201 (engineering method), except for the following:
measurements are permitted in situ; and
a)
b) a simplified method is specified for determining a local environmental
correction which yields results approximating those obtained in a free
field over a reflecting plane. This correction is used to derive the
emission sound pressure levels at specified positions, including work
stations. The results are limited to the survey grade of accuracy.
0.2 This International Standard is one of a series (IS0 11200 to
IS0 11204) which specifies various methods for determining the noise
emissions of a piece of machinery or equipment, or a sub-assembly of
such equipment (machine under test). IS0 11200 gives guidance on the
choice of the method to be used to determine the emission sound
pressure levels of machinery and equipment. It also gives details of lnter-
national Standards giving methods for the determination of sound power
levels.
