5.13.1.3 Information on noise emission

Information on noise emission shall be given by the manufacturer in the operation manual, see 7.2.

5.13.2 Noise emission measurement

5.13.2.1 Sound power level

The sound power level for the different types of earth-moving machinery shall be measured according to 15) ISO 6395:2008 ®1 unless otherwise stated in the machine specific parts of this standard.

NOTE

Noise emission values obtained from measurements are the way to verify the result of the noise reduction

measures taken at the design stage (see 5.13.1.1 and 5.13.1.2).

5.13.2.2 Emission sound pressure level at the operator's station

The emission sound pressure level at the operator's station for the different types of earth-moving machinery shall be measured according to ~ ISO 6396:2008 ®1 unless otherwise stated in the machine specific parts of this standard.

NOTE 1

On machines fitted with a cab, the A-weighted emission sound pressure level at the operator's position should

not exceed~ 80 dB (51.

NOTE 2

Noise emission values obtained from measurements are the way to verify the result of the noise reduction

measures taken at the design stage (see 5.13.1.1 and 5.13.1.2).

5.14 Protective measures and devices

5.14.1 Contaminated area

If an earth-moving machine is intended to be used in a contaminated environment, special precautions to protect the operator (e.g. fresh air filter systems or system to provide breathing air to the operator) are needed if any hazard exists (see also 5.3.1.1).

~ NOTE A special amendment is under development ®I

5.14.2 Hot parts

Parts which are hot in operation shall be designed, constructed, positioned or provided with a thermal guard to minimise the risk of contact with hot parts and/or surfaces in close proximity to the primary opening, operating position and maintenance area according to EN ISO 13732-1:2006.

5.14.3 Moving parts

All moving parts which create a hazard shall be designed, constructed, positioned or provided with protection devices to minimise the risk of crushing, shearing and cutting.

5.14.4 Guards

Guards shall be designed to be securely held in place and prevent access to dangerous areas and parts where a hazard exists.

Engine compartment panels are regarded as guards.

Guards shall comply with EN ISO 3457:2003.

Movable guards shall as far as possible remain attached to the machine when open.
