An IP rating alone does not establish suitability for an explosive atmosphere. Ingress protection and explosion protection answer different questions. A project may need evidence for both.
Keep the two scopes separate
| Evidence | What it addresses | What not to assume |
|---|---|---|
| IP classification under IEC 60529 | Degrees of protection provided by an enclosure | That an IP marking is an Ex certificate |
| Applicable Ex marking and certification | Compliance within the certified equipment’s explosion-protection scope | That any certificate covers every model or installation |
What a buyer should request
Obtain the exact model identification, its markings, the relevant certificate and the manufacturer’s instructions. Match the supplied model to the certificate scope; a logo in a brochure is not a substitute for that check. Have the responsible project specialist assess compatibility with the hazardous-area requirements and applicable local rules.
The IECEx equipment scheme concerns equipment intended for explosive atmospheres. Its certification does not remove the need to check the project’s installation conditions or local acceptance requirements. Likewise, an enclosure rating should not be treated as a promise of resistance to every chemical, impact or cleaning process.
Use the TORMIN certification document page as a starting point for requesting the applicable model documents.
