3.5 Noise
3.5.1 Reference standards
The measurements of noise emission were conducted according to the EN ISO 11202 for the
determination of sound pressure level at the operation positions. When the measured sound
pressure levels at the operation positions exceed 85dB(A), the measurements of sound power
levels were conducted according to EN ISO 3746.
3.5.2 Operating conditions
The operating conditions for noise measurement comply with Annex A of ISO 7960:1995.
3.5.3 Testing results

The figures quoted are emission levels and are not necessarily safe working levels. Whilst
there is a correlation between the emission and exposure levels, this cannot be used reliably to
determine whether or not further precautions are required. Factors that influence the actual level
of exposure of the workforce include the characteristics of the work room, the other sources of
noise etc. i.e. the number of machines and other adjacent processes. Also the permissible
exposure level can vary from country to country. This information, however, will enable the user of
the machine to make a better evaluation of the hazard and risk.”
