Hazardous Location Testing – With more than 25 years’ experience, F2 Labs can assist you with your Hazardous Location testing needs.
Intrinsic Safety (IS) Certification Evaluation – IS Design is a suitable approach to minimize the risk of ignition. The product as a whole must be evaluated. It is not enough to just have intrinsically safe components.
Hazardous Location Classes/Divisions for the US and Canada. They are categorized as follows:
Divisions
The division defines the probability of hazardous material being present in an ignitable concentration in the surrounding atmosphere.
| Division | Presence of Hazardous Material |
| Division I | ignitable concentrations of flammable gases, mist or vapors can exist under normal operating conditions |
| Division II | ignitable concentrations of flammable gases, mist or vapors are not likely to exist under normal operating conditions |
Classes
The classes define the general nature of hazardous material in the surrounding atmosphere.
| Class | Hazardous Material in Surrounding Atmosphere |
| Class I | Flammable gases, mist or vapors |
| Class II | Combustible dust |
| Class III | Ignitable fibers/flyings |
Groups
The groups define the properties of the material in the surrounding atmosphere
- A – Acetylene
- B – Hydrogen
- C – Ethylene
- D – Propane
- E – Metal Dusts (Div. 1 only)
- F – Carbonaceous Dusts
- G – Non-Conductive Dusts (flour, grain, wood, plastic, etc.)
Zones
Zones are classified by the frequency and likeliness of ignitable concentrations of flammable gases, mist, vapor, or dust, fibers/flyings being present during normal operation of the product.
| Zone Definitions | |
|---|---|
| Gases, Mists, & Vapors | Dust & Fibers/Flyings |

IECEx Scheme
IECEx Scheme is an International approval scheme intended for equipment used in a potentially explosive atmosphere. These approvals help streamline the approval process when you intend to market your product internationally.
The product is assessed and tested against the applicable IEC standards. An IECEx Certified product is issued with an IECEx Certificate and associated test report (ExTR). These documents can then be submitted to member countries as evidence that the product is in compliance.
Countries Participating in the IECEx Scheme:
- Australia
- Hungary
- Romania
- Brazil
- India
- Russia
- Canada
- Italy
- Slovenia
- China
- Japan
- South Africa
- Croatia
- Korea
- Singapore
- Czech Republic
- Malaysia
- Sweden
- Denmark
- The Netherlands
- Switzerland
- Finland
- New Zealand
