IECEx: Meaning and Requirements

IECEx: MEANING AND REQUIREMENTS

IECEx is an international certificate for electrical equipment used in explosive atmospheres (Ex equipment) intended to facilitate global trade in electrical equipment for use in hazardous locations while maintaining the required safety.

Where is Ex Equipment Typically Found?
Ex equipment is commonly found in the following industrial environments:

• Automotive refueling stations or petrol stations
• Oil refineries, rigs, and processing plants
• Chemical processing plants
• Printing industries, paper and textiles
• Hospital operating theaters
• Aircraft refueling and hangars
• Surface coating industries
• Underground coal mines
• Sewerage treatment plants
• Gas pipelines and distribution centers
• Grain handling and storage
• Woodworking areas
• Sugar refineries
• Metal surface grinding, especially aluminum dust and particles

Guidelines for Use & Installation

• A barrier is required for the installation of IS sensors. The barrier passes signals in either direction as required, but limits the voltage and current that can reach the hazardous area under fault conditions. The barrier is put in series and is installed in a safe area.
• A proper IS barrier must be used with this sensor to ensure compliance with entity parameters.
• Approved cabling (maximum 200 ft / 60 m) must be used to bring the signal from the sensor to the Zenor diode barrier or galvanic isolator, which is the energy-limiting interface.
• Sensors must be grounded to a grounded structure by stud mounting the sensor directly to the machine surface, ensuring metal (of the sensor) to metal (of the machine surface) contact.
