IECExsuojausvaatimukset

IECEx is an international certification system established by the International Electrotechnical Commission (IEC) for equipment, services, and personnel used in explosive or hazardous environments. It applies to equipment placed in explosive atmospheres, including gases, vapors, and combustible dusts, and covers electrical and non-electrical devices, protective systems, and related components.

The IECEx scheme provides conformity certificates and marks that indicate compliance with standardized requirements. Assessments are carried out by approved IECEx Certification Bodies and Assessment Services, and certificates are issued by an IECEx member body. Equipment is marked with the Ex symbol and a certificate number, enabling recognition across participating economies and facilitating cross-border trade and market access.

Standards underpinning the assessments primarily come from the IEC 60079 series for explosion protection in gas and vapor atmospheres, including related standards for dust and protective coding. The scheme also encompasses zones and protection concepts defined in those standards, such as equipment protection levels and temperature ratings, to ensure appropriate safety classifications for different hazardous environments.

IECEx comprises multiple components, most notably Equipment Certification, Service Facility Certification for repair and maintenance facilities, and, in some arrangements, Personnel Competence Certification. By providing internationally recognized certificates and marks, IECEx reduces the need for duplicate testing and national approvals, supporting safer use of electrical and non-electrical equipment in hazardous areas worldwide.
