2.1 Correspondence between hazardous areas, substances and categories


The cable glands and accessories are made to be istalled in the following areas:
• Safe area: industrial execution
• Zone 1 and 2, Zone 21 and 22: Ex db / Ex eb / Ex tb execution
• Group I (mines), category M2 (I M2)
• Group II (surface), category 2, potentially explosive atmospheres of mixture of air gases, vapours, mists, or dusts (II 2 GD)
• Groups of gas IIA, IIB e IIC
• Groups of dusts: IIIA, IIIB e IIIC
The classification of areas, foresees that hazardous areas are divided into zones based on the frequency and duration of the occurrence of an explosive atmosphere and the type of hazardous substances (liquids, gases and vapours or dust).

For more information refers to the following standards
• IEC/EN 60079-10-1 Explosive atmospheres. Part 10-1: Classification of areas - Explosive gas atmospheres
• IEC/EN 60079-10-2 Explosive atmospheres. Part 10-2: Classification of areas - Combustible dust atmospheres

2.2 EPL Apparatus Electrical installations in hazardous area

Electrical equipment for gas (Excerpt Table 2 IEC / EN 60079-14 standard)

For more information refers to the following standards
• IEC/EN 60079-14 Explosive atmospheres. Part 14: Electrical installations design, selection and erection
