The conditions for indoor measurements are the following:
Building size:
length
8 m (26’)
width
5 m (16’)
height
3 m (10’)
Type of premises:
floor
polished concrete
covering
tile
walls
masonry with side glass
Instrument used
Bruel & Kjaer mod. 2221 class 1
Reference standard
DIN 45635
The use of the machine is only allowed provided that suitable hearing protection is ensured. The employer shall hence
compulsorily provide the operators with personal protection equipment (earphones, plugs).

Vibrations
The machine was designed to minimize the effects generated by vibrations. In any case, these are associated to relevant
factors, such as the type of material to be cut and wear of the disc.
The results of the measurements carried out in the field, implementing UNI EN ISO 8662-12:1999, are the following:

Exposure time (hours)
Formula to calculate the level of daily exposure to vibrations - A(8)
For the comparison with exposure limit values and action values, the total weighted acceleration, obtained through the vector
sum of the components, shall be standardized, namely analytically referred to a reference time of 8 hours.
