Appendix B. Specifications 6578
The model specifications 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 you 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.
