ATEX Labelling of Electric Equipment - DIN-A2 Poster

Product catalog summary

Overview of Countries and Regions

The document lists numerous countries and regions worldwide, indicating a global scope or market presence relevant to the product or standards discussed.

Explosion Protection Standards and Classifications

The document extensively covers explosion protection classifications according to ATEX and EN standards, focusing on hazardous locations and equipment certification.

Explosion Groups and Temperature Classes

Explosion groups are categorized for gases, mists, vapours, and dusts, with examples such as Ammonia, Methane, Propane, Petrol, Diesel, Hydrogen, and Acetylene.
Temperature classes (T1 to T6) define the maximum surface temperature of equipment to prevent ignition, ranging from T1 (<450°C) to T6 (<85°C).

Zones and Equipment Protection Levels (EPL)

Hazardous locations are classified into zones based on the probability and duration of explosive atmospheres: Zone 0, 1, 2 for gases; Zone 20, 21, 22 for dusts.
Equipment is categorized for use in these zones with corresponding EPLs such as Ga, Gb, Gc for gases and Da, Db, Dc for dusts.

Types of Protection and Codes

Protection principles include flameproof enclosure (Exd), increased safety (Exe), intrinsic safety (Exi), pressurized apparatus (Exp), encapsulation (Exm), oil immersion (Exo), powder filling (Exq), and protection type “n”.
Each protection type is associated with specific EN 60079 series standards (e.g., EN 60079-0, -1, -5, -6, -7, -11, -18, -31, -152).
Notified Bodies (NB) issue certification codes (e.g., PTB Germany 0102, EXAM Germany 0158).

Ingress Protection (IP) Ratings

Ingress Protection is defined according to EN 60529, detailing protection against solids (dust, objects) and water (sprays, jets, immersion).
IP ratings such as IP66 indicate dust-tight and protection against powerful water jets.

Labelling and Marking of Explosion Proof Equipment

Equipment is labelled according to ATEX 2014/34/EU directives, indicating explosion group, temperature class, zone suitability, and protection type to ensure compliance and safe use in hazardous environments.

Product Examples and Specifications

ExMax Series: ¼ turn actuators with torque 5–150 Nm, voltage 24–240 VAC/DC, optional spring return.
ExMax+LIN: Linear valve units with force 500–3,000 N, stroke 7.5–42 mm, with spring return.
ExRun: Valve actuators with force 500–10,000 N, stroke 5–60 mm, without spring return.
ExCos: Analog sensors operating from −40 to +125 °C, humidity 0–100% rH, pressure ±100 to ±7,500 Pa.
ExReg: Compact controllers for temperature −40 to +125 °C, humidity 0–100% rH, pressure up to 300 Pa (VAV).
ExBin: Binary sensors with temperature −40 to +125 °C, humidity 0–100% rH, pressure 0–5,000 Pa, frost protection −10 to +15 °C, and fan belt monitoring up to 10,000 min-1.

Key Recommendations and Best Practices

Selection of equipment must consider explosion group, temperature class, and zone classification to ensure safety and compliance.
Proper labelling and certification by recognized Notified Bodies are essential for legal and operational safety.
Ingress protection ratings must be matched to environmental conditions to prevent dust and water ingress that could compromise explosion protection.
Use of appropriate protection principles (e.g., intrinsic safety, flameproof enclosure) depending on the hazardous area classification.
