Hazardous Area, Certification and Compliance: Heat Tracing Guide Hub
Hazardous area heat tracing is a compliance question before it is an engineering question: which certification, which temperature class, which documents a project file must contain. This hub collects our guides on explosion protection, certification and compliance.
Certification basics
- Ex-Proof Heat Tracing Selection: Zones and Certification — Zone 1 vs Zone 2 and which certification applies.
- ATEX and IECEx Heat Tracing: 7 Things Buyers Should Verify — a procurement checklist for certificate scope, temperature class and validity.
- Heat Tracing Cable Material and Structure — how jackets, cores and sheaths affect suitability in corrosive and hazardous environments.
Applications in classified areas
- Explosion-Proof Zone Heat Tracing Solution
- Petrochemical Plant Heat Tracing
- Offshore and Marine Heat Tracing
- LNG and Gas Facility Heat Tracing
Documentation and compliance
- Certificates and Approvals — the certifications held and the scope covered.
- Commissioning Procedure — the test records a classified-area installation needs.
- Warranty and After-Sales
What a project file should contain
| Document | Why |
|---|---|
| Certificates for each model used | Prove the exact equipment is certified |
| Area classification drawing | Confirms zone and gas group |
| Temperature class calculation | Shows the surface temperature stays within class |
| Installation instructions | Required for correct installation |
| Commissioning test records | Evidence the system was verified |
