Certifications & Hazardous Area Compliance
Explosion Proof Camera (ExPC) maintains a central technical reference for the hazardous area certifications that apply to explosion-proof camera systems. Every certification listed on this page is backed by the actual certificate, published in full.
Certification confirms that equipment complies with defined protection concepts, testing requirements and documented operating limits. It does not replace site-specific risk assessment or installation responsibility, and it applies only to the configurations described in the certificate itself.
Certifications by Product Family
Each active seal links to the certificate as issued. Where a family is not certified under a given scheme, the seal is dimmed. We publish the gaps as clearly as the coverage.

Certificate scope, gas groups, temperature classes and installation conditions are defined in each document. Always specify against the certificate, not against a summary.
How to Read an Ex Marking
Every certified enclosure carries a marking string that describes exactly where and how it may be installed. Reading it correctly is the difference between a compliant installation and an unsafe one. Select any segment below to see what it defines.
Group II covers surface industries. Group I is reserved for mining applications with firedamp.
Example marking shown for explanation only. The marking that applies to a given product is stated in its certificate.
Zone vs Division: North American and IEC Systems
Two area classification systems dominate globally. North America historically uses Classes and Divisions, and now also permits a Zone system; the IEC/ATEX world classifies hazardous areas into Zones. They describe the same physical risk with different language, and they are not interchangeable on paper. Equipment must be certified under the scheme the site is governed by.
Gas: presence of hazard
| Presence of flammable gas | North America | IEC / ATEX |
|---|---|---|
| Continuous or long periods | Class I, Division 1 | Zone 0 |
| Likely in normal operation | Zone 1 | |
| Unlikely, and short duration | Class I, Division 2 | Zone 2 |
Gas: representative groups
| Representative gas | North American group | IEC gas group |
|---|---|---|
| Propane | Group D | IIA |
| Ethylene | Group C | IIB |
| Hydrogen | Group B | IIC |
| Acetylene | Group A | IIC |
Dust atmospheres follow a parallel structure: Class II and Class III Divisions in North America, Zones 20, 21 and 22 in the IEC system. Group assignment and temperature class must both be satisfied.
Certification Frameworks
Explosion protection schemes define technical safety requirements. Market access rules define how certified equipment is accepted, registered or restricted in a given country. The two are separate, and satisfying one does not satisfy the other.
FM, and the Class/Division framework used in the United States and Canada, with the Zone system also permitted under current code.
Read the North American reference → ATEXThe European framework. Governs equipment placed on the market in the EU and defines categories tied to Zones, with conformity assessment by a notified body.
Read the ATEX reference → IECExThe international scheme. Certification issued under IEC 60079 and recognised across many jurisdictions, frequently used as the technical basis for national approvals.
Read the IECEx reference →Certified equipment may still face national requirements governing labelling, registration or acceptance within a specific market.
Certification Scope & InterpretationCertification covers documented configurations, operating conditions and installation boundaries, and nothing outside them.
ExPC Technical AuthorityCertificate references, documentation accuracy and update responsibility are maintained under a named technical authority.
