Ex Certificate Explained — ATEX and IECEx Certificates
This article covers Ex Certificate Explained — ATEX and IECEx Certificates. An Ex certificate is the formal document certifying that equipment meets Ex protection requirements. This guide explains what an ATEX or IECEx certificate contains, how to read it, and how to verify it is current.
Overview
Understanding this equipment type is important for both CompEx Ex01/Ex02 (installation and selection) and Ex03/Ex04 (inspection). EX Academy's simulations include this equipment type across multiple scenarios.
EX Academy's inspection simulations and equipment selection scenarios include this equipment type. Each scenario presents a real work order with the equipment type, zone classification, gas group, and inspection findings or selection requirements.
Key Selection and Inspection Points
For selection: verify zone, gas group, T-class, and EPL against the area classification. For inspection: check the certificate matches the area, verify all entries are sealed, check for physical damage, and classify any deficiencies using the IEC 60079-17 Category X/A/B/C system.
