Which ATEX codes are distinguished?

An ATEX-certified lamp can be identified by the certification markings printed on the lamp housing. These ATEX codes indicate the level of explosion protection and the environments in which the lamp may be safely used.

Common ATEX markings and their meanings

• CE — Confirms that the product complies with European regulations and quality requirements
• Ex — Indicates explosion protection certification
• G / D / GD — Suitable for gas atmospheres (G), dust atmospheres (D), or both (GD)
• EEx / Ex — Approved for use in explosive environments according to European standards
• e / d / i / n — Indicates the protection method used
• IIA / IIB / IIC — Gas group classification, where IIC represents the highest explosion risk
• T1 to T6 — Temperature classification based on maximum surface temperature, where T6 has the lowest surface temperature and highest safety level

ATEX certification must be issued by a notified certification body such as KEMA or DEMKO.

If a lamp is tested by a non-certified inspection body, certification is generally limited to Zone 2 applications, which represents the lowest explosion protection category.
