Maximum surface temperature of explosion-proof (Ex) equipment can be one of the sufficient causes of explosion if surface temperature is more than the ignition temperature of surrounding explosive atmosphere where Ex equipment installed. Temperature class is given for any Ex equipment/system on the basis of maximum temperature of internal component or external surface of Ex equipment depends on the type of protection method attains during normal or and under specified abnormal working condition. The temperature class is very important and essential for those equipment which are designed for hazardous areas.
