1 Scope
This International Standard specifies the technical requirements of a noise test code
for a specific family of machinery or equipment. It is primarily applicable to stationary
machinery and equipment, including hand-held tools, as well as those that present
hazards due to mobility or load lifting.
The purpose of a noise test code is to permit comparable test results to be obtained
on the noise emissions of machines from the same family, thus enabling users to make
comparisons and to check the declared noise emission data. The quantities described
in a noise test code are also useful for noise specifications in private contracts,
for planning and for noise reduction purposes.
Specific test codes for various types of machinery and equipment are established and
used in accordance with the requirements of basic International Standards. Standardized
noise test codes give detailed requirements on mounting, loading and operating conditions
for the particular family to which the machinery under test belongs, as well as the
location of a work station(s) and other specified positions (if any).
The purpose of this International Standard is to assist technical standardization
committees responsible for specific families of machinery or equipment in preparing
noise test codes to ensure that such noise test codes
-
— are in full accordance with basic standards on measurement, declaration and verification
of noise emissions; and
-
— are as homogeneous as possible, with each individual test code having the same basic
structure;
-
— reflect the latest technical knowledge of methods of determining the noise emissions
from the specific family of machinery or equipment under consideration.
NOTE 1
Annex A lists the basic International Standards to be used in the drafting of a noise test
code. An outline of a typical noise test code summarizing the information that is
required is given in annex B. Noise emission quantities are described in annex C.
