Explosive atmospheres - Equipment. General requirementsWhat is BS EN 60079 0: 2009? BS EN 60079 0 sets out the general electrical safety requirements for the construction, testing and marking of electrical equipment and components that are used in explosive atmospheres. Explosive or flammable atmospheres can be defined as temperatures of 20 C to +60 C; pressure of 80 kPa (0,8 bar) to 110 kPa (1,1 bar); and air with normal oxygen content, typically 21 % v v. This standard also covers classification systems
