TECHNICAL DATA
NOTE on noise emission:
The values indicated are emission values
and must not represent safe workplace
values as well.
Although a correlation exists between
emission levels and immission levels, it is
not always possible to determine whether
additional precautionary measures are
required.
Factors that can have an effect on the
immission level existing at the workplace
include the duration of the effects, the
characteristics of the work area and other
sources of noise, e.g. the number of ma-
chines and processing operations in the
vicinity. The permissible workplace values
may also vary from country to country.
This information, however, is intended
to enable the user to better estimate the
dangers and risks.
