NOISE TESTS
In accordance with point 1.7.4.f of the Machines Directive EEC 89/392
INTEGRATING PHONOMETER " DELTA OHM " mod. HD9019K1 serial n. 110996B295.
MICROPHONE mod. HD 9019S1.
SOUND GAUGER mod. HD 9101at 94dB/110dB a 1.000 Hz in class 1 according to IEC regulation n. 942 1988 and ANSI S1.40 1984.
3 measurements with the machine operating unloaded.
- The microphone was been located close to the operator's head, at medium height.
- The weighted equivalent continuous acoustic pressure level was 77,6 dB (A).
- The maximum level of the WEIGHTED instantaneous acoustic pressure C was always less than 130 dB.
NOTE: with the machine operating, the noise level will vary according to the different materials being processed. The user must
there-fore assess the intensity and if necessary provide the operators with the necessary personal protection, as required by Law
277/1991.
