This European Standard specifies electrical and flammability safety requirements for conveyor belts intended for use in underground installations, in the presence of flammable or non-flammable atmospheres.<\/p>\n

Conveyor belts covered by this European Standard and intended for use in flammable atmospheres are intended for use on conveyor belt installations (machinery in mines). The belt is a component or part of equipment, which can be incorporated into the conveyor, which is an equipment of Group I, Category M2, as defined in 3.2.2 of EN 13463\u20111:2009<\/span> <\/span>.<\/p>\n

This European Standard is not applicable to light conveyor belts as described in EN ISO 21183\u20111:2006<\/span> <\/span> nor is it applicable to conveyor belts which are manufactured before the date of publication of this document by CEN.<\/p>\n

This European Standard deals with those significant hazards detailed in A.1<\/span>.<\/p>\n

Attention is drawn to Annexes ZA<\/span> and ZB<\/span>.<\/p>\n

\n
\n NOTE\n <\/div>\n

A summary of the requirements of this European Standard is given in Table 2<\/span>. This is intended for quick reference only.<\/p>\n<\/div>\n
