SOR products satisfy the requirements of approval agencies worldwide. Often,
a common design is capable of multiple approvals. In other cases, modified
construction techniques are necessary to meet specific agency requirements.
Hazardous Areas are locations where the potential for fire or explosion exists because
of gases, dust or easily ignitable fibers or flyings in the atmosphere.
In North america, hazardous areas are separated by classes, divisions, and
groups to define the level of safety required for equipment installed in these locations.
Classes define the general form of the flammable materials in the atmosphere. Divisions
define the probability of the presence of flammable materials. Groups classify the exact
flammable nature of the material.
In europe and countries outside of North america, classification of hazardous areas
is accomplished differently. Zones are used to define the probability of presence of the
flammable materials. Protection Types denote the level of safety for the device. Groups
classify the exact flammable nature of the material. These groups are separated differently
than North American Groups. Temperature Identifications convey the max imum surface
temperature of the apparatus based on 104°F (40°C) ambient. These temperature codes
are selected carefully so as not to exceed the ignition temperature of the specific gas or
vapor to be encountered in the application.
Similar to hazardous location classifications, environmental protection ratings are
slightly different within and outside of North America. National Electrical Manufacturers
Association (NEMA) and Ingress Protection (IP) Codes provide similar information
regarding protection against specified environmental conditions.
NeMa 4 Indoor or outdoor use. Protection against wind-blown dust and rain, splashing water, hose-directed water and damage from external ice formation.
NeMa 4X NEMA 4, plus protection against corrosion.
IP 65 Dust-tight and protected against water jets.
IP 68 Dust-tight and suitable for indefinite immersion.
Some classifications are not shown here. For further detailed information, see
specific standards published by approval organizations.

This brochure is intended to provide suggestions for the general application of certain types of instruments. Since each application has unique characteristics, it is recommended that you consult SOR to discuss the specific details of your application to ensure the correct instrument is selected.
Classifications Inside North america
Class I Flammable gases or vapors are present in the air in quantities
sufficient to produce explosive or ignitable mixture.
Class II Combustible or conductive dusts are present.
Class III Ignitable fibers or flyings are present but not likely to be in suspension in sufficient quantities to produce ignitable mixtures. (Group classifications are not applied to this class.)
Division 1 The substance referred to by class is present during normal conditions.
Division 2 The substance referred to by class is present only in abnormal conditions, such as a container failure or system breakdown.
