This European standard specifies the safety requirements and tests for rail locomotives for use in underground mining (i.e. mine locomotives) and other underground workings (e.g. tunnelling locomotives). 1.1 This European standard deals with the technical requirements to minimise the hazards listed in clause 4 which can arise during the commissioning, the operation and the maintenance of locomotives when carried out in accordance with the specifications given by the manufacturer or his authorised representative. 1.2 This European standard does not address the special hazards associated with the rack drive of rack and pinion locomotives. 1.3 This European standard does not deal with radiation and vibration. It does not address remote control locomotives or operation in potentially explosive atmospheres. Hazards due to noise are excluded from this standard, but a separate standard is in preparation where hazards due to noise will be addressed. 1.4 This European standard applies to locomotives which are manufactured after the date of issue of this standard.
