NOTE For machines and their related products intended to be put on the market in the EEA, the EMC-Directive may also apply."
5.4 Thermal hazard
Control knobs that have to be handgripped shall not exceed a 55°C temperature
The parts of the presses surface that can come into contact with the operator shall not exceed a 65°C temperature In all other cases guards shall be provided
5.5 Noise reduction
!Noise reduction shall be an integral part of the design process, thus specifically taking into account
measures at sources as given in EN ISO 11688-1:2009 The success of the applied noise reduction measures
is assessed on the basis of the actual noise emission values in relation to other machines of the same family
As this type of machines is in general not totally assembled in the factory, the noise emission values required for the conformity declaration can normally only be determined at the purchaser's site The measurement,
