5 ENELE-E AN NE OMPARSON nternational electrotechnical ommission ( The E (nternational Electrotechnical ommission), created in 1904 in Geneva (Switzerland) establish the E regulations. n 1947, with the creation of the nternational Standards Organisation (SO) by the United Nations, the E became responsible for the organisation of the electrical division, while still remaining independant. The E has defined three categories of hazardous zones: - 0 : the explosive atmosphere is continuously present. - 1 : the explosive atmosphere is often present. - 2 :the explosive atmosphere may accidentally be present. Gas and vapour classification Gases are divided into four groups by the E and the NE (with some additional gases). The E also defines different groups of gases and vapours. The E and North American groups are viewed as fundamentally the same, apart from the fact that there are three groups in the E and four for the NE. (See table as follows) Temperature classification E defined a temperature classification for materials used in hazardous areas. Following this, E and NE have also been modified to include a temperature classification.
