scope:

This standard applies to flashlights and lanterns that employ primary (non-rechargeable) and secondary (rechargeable) cells or batteries.

Electrical apparatus intended for use in Class I, Division 2 hazardous (classified) locations is apparatus in which any spark or thermal effect, produced under normal conditions, is incapable of causing ignition of a specified mixture of flammable or combustible material in air.

Electric flashlights and lanterns intended to be used in Class II (combustible dusts) or Class III (flyings and fibers) hazardous (classified) locations are those which contain a dust-tight enclosure and are incapable of causing ignition of a specified dust or fiber.

The requirements of this standard are based on consideration of ignition in locations made hazardous by the presence of flammable or combustible material under normal atmospheric conditions. For the purposes of this standard, normal atmospheric conditions are generally considered to be:

1) an ambient temperature of -20°C to +40°C;

2) an oxygen concentration of not greater than 21 percent by volume; and

3) a barometric pressure in the range 0.8 atmosphere to 1.1 atmosphere.

Note: Equipment specified for atmospheric conditions beyond the above limits is subject to special investigation.

Purpose

This standard states testing and certification requirements for electric flashlights and lanterns for use in Class I, II and III, Division 2 hazardous (classified) locations as defined in the National Electrical Code^®, ANSI/ NFPA-70 (NEC^®).

Testing and certification criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
