Specifications Information (ISO/ANSI)
The model specifications information on the following
pages was determined in controlled acoustical
environments according to procedures specified by the
American National Standards Institute (ANSI) S12.10 and
ISO 7779, and are reported in accordance with ISO 9296.
Actual sound pressure levels in your location might differ
from the average values stated because of room
reflections and other nearby noise sources.
The declared
sound power levels indicate an upper limit, below which a
large proportion of machines will operate.
