2.5 -- Airborne noise from the machine

Noise causes damage to hearing and is a problem that many

countries tackle by laying down specific regulations. In

conformity with the regulations established by the Machinery

Directive 98/37/CE/EEC, we hereby informyou of the standards

prescribing the sound level threshold for machine tools. This

chapterprovidesthevaluesofairbornenoiselevelsgeneratedby

the P 225 in the various stages of its operation and the method

used for measuring the sound level values. This situation is

regulated in ITALY by the D.M.no.277/91 which has adoptedthe

Community Directives 80/1107/EEC, 82/605/EEC,

83/477/EEC, 86/188/EEC, 88/642/EEC.

2.5.1 -- Methods of measuring sound level values

The sound level measurements are carried out using an

instrument called an Integrating sound level meter which

serves to measure the weighted equivalent continuous sound

pressure level at the workplace.

The damage caused by noise depends on three factors: level,

frequency distribution and duration. The concept of equivalent

level Leq combines the three factors so as to provide just one

simpleparameter.TheLeq isbasedontheequalenergyprinciple

and represents the continuous stationary level with the same

energycontent,expressed in dBA, astherealfluctuating levelin

the same period of time.

This calculation is performed automatically by the integrating

sound level meter. Each measurement lasts for 60 seconds to

allow the value to stabilise; the value obtained remains on the

display to give the operator time to read it.

Measurements are made with the equipment held at a distance

ofabout1 metrefromthe machineandat aheight of1.60mfrom

the operator’s workplace platform. Two measurements are

made: the first while the machine is performing a manual cut

without a workpiece; the second while the material is being cut

manually.

2.6 -- Electromagnetic compatibility

As from 1 January 1996 all electrical and electronic appliances

bearing the CE marking that are sold on the European market

must conform to Directive 89/336/EEC and decree law no.

476/92 concerning electromagnetic compatibility, i.e. the

compatibilityofelectrical/electronicdevicesandsystemswiththe

electromagnetic environment in which they are located. The

prescriptions regard two specific aspects in particular:

1 “EMISSIONS: during its operation, the appliance or system

must not emit spurious electromagnetic signals of such

magnitude as to contaminate the surrounding electromagnetic

environment beyond clearly prescribed limits”;

2 “IMMUNITY: the appliance or system must be able to operate

correctly even when it is placed in an electromagnetic

environment that is contaminated by disturbances of defined

magnitude”.
