Explosion Protected Equipment
For equipment which is intended to be used in explosive atmospheres, a number of standard methods of protection against ignition have been established. These have been adopted into construction standards and codes, which allow manufacturers to make equipment of a uniform type and have this equipment tested and certified for compliance with the relevant standards.
Read moreEquipment Surface Temperature Classification
Classification of the maximum surface temperature of equipment has been established internationally to create a uniform reference table (unless otherwise specified on equipment selected, the maximum ambient temperature is taken as being 40°C, in line with IEC 60079 Standards). The purpose of the temperature classification is to place equipment into an appropriate category according to its specific thermal properties when exposed to the worst case conditions.
