Based on standard ATEX category system for dust or gas:
| Marking element | Typical value | Meaning |
|----------------|---------------|---------|
| II | Group II | Surface industry (not mining) |
| 1/2 D or 2 D | Category | 1/2 D = equipment for zone 20/21 interface; 2 D = zone 21 |
| T rating | T85°C, T100°C | Max surface temp (dust layer consideration) |
| IP rating | IP6X | Dust-tight |
Example full marking:
II 1/2 D Ex ta IIIC T85°C Da/Db IP6X
🔍 You must read the actual product label – the certificate covers specific variants.
| Role | Responsibility |
|-------|----------------|
| Manufacturer | Issue EC Declaration of Conformity, maintain technical file |
| User/Employer | Risk assessment (DIR 1999/92/EC), zone classification, correct selection |
| Installer | Follow certificate & EN 60079-14 |
If used outside EU, check local acceptance (IECEx equivalent may exist).
The suffix "X" at the end of an ATEX certificate number indicates Special Conditions for Safe Use.
Why this matters:
It means the equipment cannot be used in a standard way. There are specific restrictions or requirements you must follow, or the certification is void and the equipment becomes dangerous.
Common "X" conditions include:
Action Item: You must check the actual PDF of the certificate or the user manual for a section titled "Special conditions for safe use". If you ignore these, the equipment is not legal to use in a hazardous zone.
| Symptom | Possible cause | ATEX-related fix |
|---------|----------------|------------------|
| No output change | Paddle stuck by material | Do not hammer – isolate, clean in safe area |
| Housing cracked | Impact/UV damage | Replace entire unit – cannot repair ATEX enclosure |
| Missing marking | Label worn off | Unit is non-compliant – remove from hazardous area |
| “X” condition ignored | Wrong electrical parameters | Check certificate – risk of ignition |
