The Directive ATEX is named after the French "ATmospheres EXplosives" and has been mandatory from 1st July 2003.
The Directive covers a surprisingly large range of equipment, potentially including equipment used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be present.

T2: 300 Celsius
