Intro to IECeX standard for Hazardous Area Classification IECeX is an International Electrotechnical Commission (IEC) system for certification to standards relating to equipment for use in explosive atmospheres. IECeX provides a means for manufacturers, regulators and users of equipment used in hazardous areas to address the risk of fires or explosions from flammable gases or dusts. Testing and certification of equipment, services and competence of persons to international standards facilitates the sale of safer products internationally at a lower cost.
Introduction to Hazardous Area Classification (HAC) A hazardous area is defined as a location where its atmosphere contains, or may contain, in sufficient quantities, flammable or explosive gases, dusts or vapor. In such an atmosphere a fire or explosion is possible when three basic conditions are met. —Omazaki Engineering is a HAC or HazLoc consultant, as business unit in Omazaki Group, who serves IECeX, ATEX or NEC electrical hazardous area classification or hazardous (classified) location classifications consulting services in Indonesia.
