Product standards are usually based on international, regional, national, industry, and enterprise. This article focuses on introducing national and alliance standards of explosion proof luminaires.

Note: This article is published by the CESP Technology Center in conjunction with the global explosion-proof standard system. If you have any questions, please contact us.

National standards:

• China GB
• German DIN
• Canada CAN
• British BS

Regional standards:

• European Community Standard (CEN)
• European Committee for Electrotechnical Standardization (CENELEC)

International level standards:

• International Organization for Standardization (ISO)
• International Electrotechnical Commission (IEC)

The standards usually implemented by our explosion-proof lamps include:

• Chinese national standard GB
• S. nationally recognized UL
• Canadian National Standard CSA
• EN recognized within the European Union
• IEC issued by the National Electrotechnical Commission

According to the different explosion-proof systems, the global explosion-proof luminaires are also divided into two categories: Zone system standards and Division system standards. Among them, the parent standard of the Zone system is the IEC 60079 series of standards, and other standards are equivalent, modified, and directly quoted based on it as the parent standard.

Zone system:

• China-GB 3836 series
• International -IEC 60079 series
• Europe-EN 60079 series
• Canada-CSA 60079 series
• United States-UL 60079 series, ISA 60079 series
• GB 12476 series (dust)
• IEC 61241 series (dust)

Division System:

 

Explosion-proof standards of UL involving specific products:

• UL 783-Electric Flashlights and Lanterns for Use in Hazardous (Classified) Locations
• UL 844-Standard for Safety Luminaires for Use in Hazardous (Classified) Locations
• UL 674-Standard for Safety Electric Motors and Generators for Use in Hazardous (Classified) Locations
• UL 2225-Standard for Safety Cables and Cable-Fittings For Use In Hazardous (Classified) Locations
• UL 823-Electric Heaters For Use In Hazardous (Classified) Locations
• UL 121203-Portable Electronic Products Suitable for Use in Class I and II, Division 2, Class I, Zone 2 and Class III, Division 1 and 2 Hazardous (Classified) Locations
• UL 894-Switches for Use in Hazardous (Classified) Locations ( UL1203 replaced)
• UL 1207-Sewage Pumps for Use in Hazardous (Classified) Locations (replaced by UL674)
