Intriniscally safe power supplies for use in coal mines -- Specification for d.c. power supplies
This Part of BS 6182 specifies requirements for the construction and testing of a range of power supply units intended to be certified intrinsically safe for use in coal mines and which provide an intrinsically safe d.c. output as follows:
It is intended that the components forming the power supply circuit be assembled on to a chassis that may be incorporated within either a flameproof enclosure or, where the power supply is located outside a potentially explosive atmosphere, within some other suitable enclosure. Requirements for these enclosures are not given in this standard. Guidance on interconnection with other apparatus is given in Annex A.
In addition to the definitive requirements, this standard also requires the information detailed in clause 4 to be documented. For compliance with this standard, both the definitive requirements and the documented item has to be satisfied.
