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:<\/p>\n

    \n
  1. an 18 DC type power supply provides a nominal 18 V output that may be used, for example, to float charge an intrinsically safe battery with a nominal discharge end-point voltage of 12 V;<\/li>\n
  2. a 12 DC type power supply provides a nominal 12 V output for use where battery standby is not required, or to float charge an intrinsically safe battery with a nominal discharge end-point voltage of 7.5 V;<\/li>\n
  3. a 7.5 DC type power supply provides a nominal 7.5 V output that may be used, for example, with equipment using logic circuits requiring 5 V for operation.<\/li>\n<\/ol>\n

    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.<\/p>\n

    In addition to the definitive requirements, this standard also requires the information detailed in clause 4<\/b> to be documented. For compliance with this standard, both the definitive requirements and the documented item has to be satisfied.<\/p>\n
