At the beginning of this century, electrification of coal mines was more or less developed in industrial European countries. In order to avoid catastrophic fire damp explosions the different national authorities set up rules and technical provisions for the construction and testing of electrical equipment for the coal mines. Each country has its own rules, often with significant differences. With the technical progress and the Rome treaty, the members states of the European Economic Community have felt the need to harmonise their national regulations in order to facilitate commercial exchanges. This task was given in 1968 to the European committee for the co-ordination of electrotechnical standards (CENELCOM). The technical committee TC 31 started this work based on different national standards and regulations. Enlarged in 1972 due to the entry of new members in the European Community and those of EFTA, CENELCOM became, the 1st of January 1973, CENELEC. The 1st of March 1977, CENELEC adopted seven standards for electrical apparatus for use in potentially explosive atmospheres.
