DIN EN 50628:2016-11

This European Standard DIN EN 50628 (VDE 0118-10) specifies the safety requirements for electrical installations to be erected in underground mining. This standard supplements other relevant harmonized standards insofar as they relate to electrical installation; for example, the standards of the VDE 0100 series as well as the VDE 0101 series. This standard also refers to the EN 60079 (VDE 0170) series of standards and its associated standards for the construction, testing and marking requirements of suitable electrical equipment. DIN EN 60079-14 gives the specific requirements for design, selection and erection of electrical installations in explosive atmospheres. DIN EN 60079-14 (VDE 0165-1) can apply to electrical installations in mines where explosive gas atmospheres other than firedamp can be formed and to electrical installations in the surface installation of mines. This standard applies to: a) electrical installation in underground workings of mines; b) electrical installations and parts of electrical installation above ground, which are directly connected with the underground workings in functional and safety relating matters because of being part of the underground working process: These are in particular: - safety and monitoring devices relating to the power distribution of the underground workings, - communication system of hoisting and inclined haulage plants, - intrinsically safe electrical installations of above ground installation being part of underground workings, - remote control systems if they shall fulfil increased requirements relating to functional safety, - electrical installation and electrical equipment of ventilation systems and shaft casings above ground being endangered by firedamp of the underground ventilation, - firedamp drainage systems; c) electrical installation in underground workings outside mining if this is required by the competent authority or the relevant employers' liability insurance association. The standard has been written in two columns in accordance with its possible applications. - The requirements in the left-hand column apply to coal mines that may be endangered by firedamp. - The requirements in the right-hand column apply to mines in the hard coal industry that cannot be endangered by firedamp and to mines in the non-coal industry, for example potash mines. The requirements written across both columns apply to all mine workings. National regulations of the mining authority shall remain unaffected. The responsible committee is DKE/K 238 "Errichten elektrischer Anlagen im Bergbau unter Tage" ("Erection of electrical installations in underground mines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
