EN 12649:2008+A1:2011 (E) 4 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. SIST EN 12649:2008+A1:2011

For hazards which are to be reduced by the application of standards, refer to those such as
!EN ISO 13857:2008", EN 614-1:2006, EN 60204-1:2006 and EN 60745-2-12:2003, the manufacturer shall carry out a risk assessment to establish 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 11688-1:2009". 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 11201:2010" at the control sta-tion(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.

EN 12649:2008+A1:2011 (E) 12 sound power level shall be determined according to !EN ISO 3744:2010" (if the emission sound pressure exceeds 80 dB(A)); 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 taking account of technical progress and means of reducing vibration, for guidance see CR 1030-1:1995. Measurements of hand-arm (e.g. for pedestrian-controlled or portable smoothing machines) and whole-body (ride-on machines only) vibration shall be made according to EN 1032:2003 and EN ISO 20643:2005. 5.1.3 High-pressure fluid injection hazard from hydraulic or pneumatic systems The systems and their components of the equipment shall fulfil the requirements of EN 982:1996 and EN 983:1996. 5.1.4 EMC The electrical equipment of machinery and plants shall comply with EN 13309:2000. 5.1.5 Fire protection On operator’s places where flammable materials be used, the burning rate shall not exceed 200 mm/min tested in accordance with ISO 3795:1989. 5.1.6 Electronically controlled systems The electronically controlled systems shall comply with EN ISO 13849-1:2006. 5.2 Safety requirements 5.2.1 Safety requirements for internal vibrators Table 2 — Safety requirements for internal vibrators Number Hazard Group Hazard Reference to EN ISO 12100-1: 2003 Safety requirements/protective measures 5.2.1.1 Mechanical hazard Drawing-in hazard unguarded transmis-sion parts 4.2.1 Rotating parts (for example coupling to flexible shaft or rotating mass) shall be protected with fixed guards.
other rotating parts
Enclosing guards shall be designed in accor-dance with EN 953:1997 considering the safety distances of

Protection from direct contact shall be ensured in accordance with EN 60204-1:2006, 6.2.
indirect contact
Protection from indirect contact shall be en-sured in accordance with EN 60204-1:2006, 6.3.

External influences on elec-trical equipment
Adequate electric protection (safety in case of a fault) shall be ensured by using:
damage to electrical equipment
measures according to EN 60204-1:2006, 6.3.2, to prevent the occurrence of a hazard-ous touch voltage, or
using sources for PELV in accordance with EN 60204-1:2006, 6.4. The source for PELV may be one of the fol-lowing: a safety-isolating transformer;
a source of current providing a degree of safety equivalent to that of the safety-isolating transformer (e.g. a motor gen-erator with winding providing equivalent isolation);
an electro-chemical source (e.g. a bat-tery) or another source independent of a higher
