What is BS EN 50628‒ Electrical installations in underground mines about?
BS EN 50628 is an international standard that covers safety requirements for the erection of electrical installations.
BS EN 50628 is supplementary to other relevant harmonized standards, like HD 60364 series and the EN 61936 series as regards electrical installation requirements. It also refers to EN 60079-0 and its associated standards for the construction, testing, and marking requirements of suitable electrical equipment.
Note 1: BS EN 50628 applies to:
- Electrical installation in underground workings of mines
- 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
- Electrical installation in underground workings outside mining if it is demanded of the competent national authorities
Who is BS EN 50628‒ Electrical installations in underground mines for?
BS EN 50628 on electrical installations in underground mines is useful for:
- Designers of electrical equipment for an explosive atmosphere
- Manufacturers of safety equipment for an explosive atmosphere
- Underground mining authorities
- Oil and petroleum gas industries
- Industries with the explosive work atmosphere
Why should you use BS EN 50628‒ Electrical installations in underground mines?
When electrical equipment is to be installed in underground workings, where an explosive atmosphere is likely to occur, protective measures are applied to avoid the ignition of firedamp. They can be applied under normal operation of the electrical installation or under fault conditions.
BS EN 50628 provides you with a comprehensive overview of the essential requirements for the erection of electrical installations in underground mining which may occur in explosive atmospheres.
BS EN 50628 gives you precautionary measures that are necessary to ensure the safety and monitoring of devices relating to the power distribution of the underground workings as well as the communication system of hoisting and inclined haulage plants.
BS EN 50628 gives you guidelines for intrinsically safe electrical installations of above-ground installation being part of the underground workings, electrical installation and electrical equipment of ventilation systems and shaft casings above ground being endangered by firedamp of the underground ventilation along with firedamp drainage systems for protection purposes to avoid any mishaps while installing the electrical equipment underground.
