Class, Division and Group Information

The National Electric Code (NEC)/National Fire Protection Association 70 (NFPA) Article 500 lists three Hazardous (Classified) Locations which indicates the nature and degree of a hazard existing in a particular location. Article 500 provides a general description for Class 1. Article 501 provides specifics.

  • A Class 1 Locations “are those in which flammable gasses, flammable liquid-produced vapors or combustible liquid-produced vapors, are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures”.

The two Division designations defines the chance a hazardous material is present in an ignitable concentration. Article 500 provides a general description for Division 1 and 2.

  • A Division 1 location is one in which:
    1. “Ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors can exit under normal operating conditions”.
    2. “Ignitable concentrations of such flammable gases, flammable liquid-produced vapors or, combustible liquids above their flash points may exist frequently because of repair or maintenance operations or because of leakage,” or
    3. “Breakdown or faulty operation of equipment or processes might release ignitable concentrations of flammable gases, flammable liquid-produced vapor, or combustible liquid-produced vapors and might also cause simultaneous failure of electrical equipment in such a way as to directly cause the electrical equipment to become a source of ignition”.

Environments for the three classes with two divisions of explosion proof lighting.  The chart lists applications such as oil rigs in class 1, coal mines in class 2, and paper mills in class 3

The four NFPA Article 500 Class I Group Designations represents a specific subclassification of the nature of the hazard categorized by a common character; the four groups are listed in the below table:

Group Designation Hazard Description (Type)
Group A Acetylene
Group B Flammable gas, liquid-produced vapor, combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value less than or equal to 0.45 mm or minimum igniting current (MIC) ratio less than or equal to 0.40. Typical material is hydrogen.
Group C Flammable gas, liquid-produced vapor, combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than 0.45 mm and less than or equal to 0.75 mm, or minimum igniting current (MIC) ratio greater than 0.40 and less than or equal to 0.80. Typical material is ethylene.
Group D Flammable gas, liquid-produced vapor, combustible liquid-produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than 0.75 mm, or minimum igniting current (MIC) ratio greater than 0.80. Typical material is propane.

Certification Information

Underwriters' Laboratories (UL): provides testing, inspection, and certification services.

UL Standard 844: Luminaires for Use in Hazardous (Classified) Locations
Requirements for fixed and portable luminaires for installation and use in hazardous (classified) locations.

UL Standard 1598: Luminaires
Applies to luminaires for use in non-hazardous locations that are intended for installation on branch circuits of 600 V nominal or less.

UL Standard 1598A: Supplemental Requirements for Luminaires for Installation on Marine Vessels

Supplement to 1598, applies to luminaires for installation on marine vessels utilizing grounded systems in accordance with the United States Coast Guard Electrical Engineering Regulations.

ATEX (French Acronym, French ATmosphère EXplosibles) - European Union (only) directives describing minimum safety requirements for workplaces/equipment in explosive atmospheres applications. ATEX is driven by EU law.

IECEx (International Electrotechnical Commission (IEC) for use in explosive atmospheres (Ex)) IECEx is a voluntary certification.

IP66 Ingress Protection (IP) Classification - defines the degree of protection against particles and the extent of protection against water for enclosures. Based on the International Electrotechnical Commission (IEC) standardized International Protection Code. IEC 60529.

  • Corresponds to NEMA (National Electrical Manufacturers Association) equivalent rating Type 7.

Note:
The Class I Division 1 certification is the most stringent, these listed products are also certified for the following locations:
Class I, Division 2, Groups A, B, C & D
Class II, Division 1, Groups E, F, G
Class II, Division 2, Groups F & G
Class III
