Description of BS 6182-2:1982 1982

This Part of this standard specifies requirements for the construction and testing of a range of mains fed power supply units intended to be certified intrinsically safe for use in coal mines and which provide an intrinsically safe a.c. output of the following voltages:

  1. a 12 V r.m.s. output to supply intrinsically safe apparatus where maximum power availability is the predominant requirement;
  2. a 15 V r.m.s. output to supply intrinsically safe apparatus where a higher operating voltage is more important than available power.

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 unit is located outside a potentially explosive atmosphere, within some other suitable enclosure. Requirements for these enclosures are not given in this standard.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.



Specifies the requirements for the construction and testing of a range of mains-fed power supply units. The power supplies provide an intrinsically safe a.c. output.
