    Abstract - (Show below) - (Hide below)

    Describes electrical and flammability safety requirements for conveyor belts intended for use in underground installations, in the presence of flammable or non-flammable atmospheres.

    Scope - (Show below) - (Hide below)

    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. 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 EN13463‑1:2009 . This European Standard is not applicable to light conveyor belts as described in ENISO21183‑1:2006 nor is it applicable to conveyor belts which are manufactured before the date of publication of this document by CEN. This European Standard deals with those significant hazards detailed in A.1. Attention is drawn to AnnexesZA and ZB. NOTE A summary of the requirements of this European Standard is given in Table2. This is intended for quick reference only.
