Introduction
This document is a type C standard as stated in EN ISO 12100-1:2003.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indi-
cated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the pro-
visions of this type C standard take precedence over the provisions of the other standards for machines that have
been designed and built according to the provisions of this type C standard.
In this standard it is assumed that:
only competent persons operate the machine;
components without specific requirements are:
a) designed in accordance with good engineering practice and calculation codes, including all failure modes;
b) of sound mechanical and electrical construction according to the state of the art;
c) made of materials with adequate strength and of suitable quality;
d) made of no harmful materials, such as asbestos;
components are kept in good repair and working order, so that the required characteristics remain despite
wear;
installation allows for safe use of the machine;
negotiation occurs between the manufacturer and the user/purchaser concerning particular conditions of use
and the places (e.g. ground and local safety conditions) of use of the machinery.
NOTE ”Manufacturer” is to be understood within the European Union as intended in the Machinery Directive.

---------------------- Page: 12 ----------------------
SIST EN 12649:2008
EN 12649:2008 (E)
For hazards which are to be reduced by the application of standards, refer to those such as EN 294:1992, EN 614-
1:2006, EN 60204-1:2006 and EN 60745-2-12:2003, the manufacturer shall carry out a risk assessment to estab-
lish the requirements of these standards which are to be applied. This specific risk assessment according to
EN 1050:1996 is part of the general risk assessment of the machine.
Where the means reduce the risk is by a safe operation of the machine, the manufacturer shall include in the infor-
mation for use details of the safe operation and the elements of training required by the operating personnel.
5.1 General requirements for all machines
5.1.1 Hazards generated by noise
5.1.1.1 Noise reduction at source at the design stage
Main noise sources are the main drive and through its vibrating parts.
When designing the machinery, the available information and technical measures to control noise at the source
shall be taken into account, see for example EN ISO 11688-1:1998.
NOTE EN ISO 11688-2:2000 [1] gives useful information on noise generation mechanism in machinery.
5.1.1.2 Noise reduction by protective devices
Noise can be reduced for example by the following means: the use of machinery components with low-noise emis-
sion encapsulation.
5.1.1.3 Noise reduction by information
Information on residual risk, after technical measures to control noise emission have been implemented, shall be
given by the manufacturer, see Clause 7.
5.1.1.4 Operation conditions during test
Operation conditions that are typical of nominal operation of concrete compactors and smoothing machines defined
in the scope of this standard and providing the highest level shall be chosen.
5.1.1.5 Determination of the A-weighted emission sound pressure level at the control station
A-weighted sound pressure levels shall be measured according to EN ISO 11201:1995 at the control station(s) at
or on the machines.
The measurement points shall be at a height of 1,55 m plus/minus 0,075 m. If there is a seat at the control station,
the measurement point is at a height of 0,80 m plus/minus 0,05 m above the seat.
Positions of the measurement points (control station(s)) and detailed information on the operating conditions during
the noise measurement shall be recorded and reported.
If the sound pressure level is higher than 70 dB(A), the sound pressure level shall be given in the operating man-
ual. If the sound pressure level is lower than 70 dB(A), this fact shall be indicated in the operating manual. Detailed
information on operating conditions during the measurement of noise shall be recorded and reported.
5.1.1.6 Determination of the A-weighted sound power level
The manufacturer shall give information on noise emission. In the absence of a noise-test code, the following ap-
plies:
sound power level shall be determined according to EN ISO 3744:1995 (if the emission sound pressure ex-
ceeds 80 dB(A));
11
---------------------- Page: 13 ----------------------
SIST EN 12649:2008
EN 12649:2008 (E)
operating conditions of the machinery during noise emission measurement shall be detailed with the noise
emission values.
5.1.2 Hazards generated by vibration
Degeneration of the hand-arm-nervous system caused by hand-arm vibration and degenerative alteration of the
vertebral column caused by whole-body vibration.
Machinery shall be so designed and constructed that risks resulting from vibration are reduced to the lowest level
