The UL913 standard covers Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III,
Division 1, Hazardous (Classified) Locations.
Lightwave UL certification can be traced to UL’s website:

Company
Name: Lightwave
Keyword: Flashlights
The specified and marked Lightwave products are classified for: Class 1, Division 1, for flashlights, which includes
"intrinsically safe" for those designated locations. Intrinsically safe means
our designs will limit temperature and
energy within the flashlight (in the context of Class 1, Division 1 test procedures). Intrinsically safe definition: "Any spark or thermal effect that may occur in normal use, or under any conditions
of
fault likely to occur in practice, is incapable of causing an ignition of the prescribed flammable gas, vapor or dust."
(a) "Normal use" is 1.2 times nominal operating voltage, and worst-case component tolerances.
(b) "Fault condition" is
a test factor of 1.5 x nominal operating voltage, under category "ia" fault conditions
(Two faults applied for Class 1, Division 1 testing).
The National Electric Code defines hazardous location classifications and protection techniques.
The
basic designation is by ''class'' and ''division.''
Class I locations are areas where flammable gases may be present in sufficient quantities to produce
explosive or flammable mixtures.
Class
II locations can be described as hazardous because of the presence of combustible dust.
Class III locations contain easily ignitable fibers and flyings.
Division 1 designates
an environment where flammable gases, vapors, liquids, combustible dusts or ignitable fibers
and flyings are likely to exist under normal operating conditions.
Division 2 is an environment where flammable gases, vapors,
liquids, combustible dusts or ignitable fibers and
flyings are not likely to exist under normal operating conditions.
Hazardous atmospheres are further defined by ''groups.''
Group A: Atmospheres containing
acetylene.
Group B: Atmospheres containing hydrogen, gases or vapors of equivalent hazard such as manufactured gas.
Group C: Atmospheres containing ethyl-ether vapors, ethylene, or cyclo-propane.
Group
D: Atmospheres containing gasoline, hexane, naptha, benzene, butane, propane, alcohol, acetone, benzol,
lacquer solvent vapors, or natural gas.
Group E: Atmospheres containing metal dust - including aluminum,
magnesium, and their commercial alloys, and
other metals of similarly hazardous characteristics.
Group F: Atmospheres containing carbon black, coal or coke dust.
Group G: Atmospheres
containing flour, starch, or grain dusts.

Locations (IKBR.E224348 and IKBR7.E224348)

Flashlights and lanterns Listed for any of the groups under Class I hazardous locations have
been tested with
respect to use in the presence of specific flammable gas or vapor-air atmospheres. Those Listed for any of the
groups under Class II hazardous locations have been tested with respect to use in the presence of specific
combustible
dusts. The tests have been conducted using specific lamp and battery combinations.
The lamp designation and the number, type, size and voltage of the batteries to be used are marked on the
product. The products covered by these Listings are provided
with a filament disconnect mechanism or other
type of construction to protect against ignition of the specified hazardous atmosphere. The filament disconnect
mechanism is intended to disconnect the lamp bulb from the circuit when the glass bulb
or envelope surrounding
the lamp filament is broken.
Safety of operation in the presence of explosive mixtures may be endangered if replacement parts other than
those specified on the product are used.
UL Classified (USA): The basic standard
used to investigate products in this category is UL783,
"Electric Flashlights and Lanterns for Use in Hazardous Locations, Class I, Groups C and D" .
UL Certified for Canada: The basic standard used to investigate products in this category
is
CAN/CSA C22.2 No. 157-92 "Intrinsically Safe and Non-incendive Equipment for Use in Hazardous Locations."
