Standard BAS EN 50303: 2020, Group I, category M1 equipment intended to remain functional in atmospheres endangered by firedamp and/or coal dust, has been adopted by the translation method.

This BiH standard is identical to the European standard EN 50303: 2000, Group I, category M1 equipment intended to remain functional in atmospheric endangered by firedamp and/or coal dust.

This standard specifies the design, construction, testing and marking requirements for Group I Category M1 equipment intended to remain operational in underground parts of mines, as well as those parts of surface installations of such mines endangered by firedamp and/or coal dust clouds under normal atmospheric conditions of pressures ranging from 0.8 bar to 1.1 bar and temperatures ranging from - 20 ° C to + 60 ° C.

It also applies to all electrical and non-electrical equipment that may cause an explosion by its own potential ignition source.

It also applies to cables, pipes and optical fibres when such items are used to carry energy sources and form part of equipment intended to remain functional in an atmosphere endangered by firedamp and/or coal dust.

BiH standard BAS EN 50303: 2020 has been prepared by the Technical Committee BAS/TC 6, Equipment for explosive atmospheres.
