scope:

This European Standard is applicable to tunnelling machinery asdefined in Clause 3 used for the construction of tunnels, shaftsand other underground excavations. It deals with all significanthazards, hazardous situations and events relevant to such machinerywhen they are used as intended and under the conditions of misusewhich are reasonably foreseeable by the manufacturer (see Clause4). This European Standard covers monitoring for hazardousatmospheres within the confines of the tunnelling machinery.Hand-arm and whole-body vibration are not considered as significanthazard for tunnelling machinery. The following items andapplications are not covered by this European Standard:- theadditional requirements for the use of tunnelling machinery underhyperbaric conditions; - the additional requirements for use oftunnelling machinery in potentially explosive atmospheres; NOTE Forthe application in potentially explosive atmospheres see EN1710:2005+A1:2008 for guidance; - ancillary tools and equipmentwhich are not an integral part of the tunnelling machinery but usedon or with the machinery; - services (e. g. power supply, water,pipes, compressed air, etc.) supplied to the tunnelling machinery;- loading and transport equipment which is not an integral part ofthe tunnelling machinery, e. g. man riders, locomotives, groutcars, segment cars, muck cars and shaft hoisting equipment. ThisEuropean Standard is not applicable to road headers, continuousminers and impact rippers. This European Standard is not applicableto tunnelling machinery which is manufactured before the date ofpublication of this European Standard by CEN.
