Marking and Application Guide
INFORMATION ON UL MARKS
There are several types of UL Marks that can be found on alternative energy equipment. General
information on each of these Marks is provided below. Each has its own specific meaning and
significance. The only way to determine if a product has been certified by UL is to look for the UL
Mark on the product itself.
The UL Mark on a product means that UL has tested and evaluated representative samples of
that product and determined that they meet the requirements in the applicable standard(s). Under
a variety of UL programs, certified products are periodically checked by UL at the manufacturing
facility to determine that they continue to comply with the standard(s).
The UL Marks may only be used on, or in connection with products certified by UL, and under the
terms of a written agreement between the manufacturer and UL.
UL Listing Mark
This is one of the most common UL Marks. If a product carries this Mark, it means UL found that
representative samples of this product met UL’s safety requirements. These requirements are
primarily based on UL’s own published Standards for Safety, or other recognized third party
standards. The UL Listed Mark includes the UL symbol, the word ―Listed,‖ the product or category
name, and a control number assigned by UL.
UL Classification Mark
This Mark appears on representative samples of products that UL has evaluated but only with
respect to specific properties, a limited range of hazards, or suitability for use under limited or
special conditions. The UL Classified Mark includes the UL symbol, the word ―Classified,‖ a
statement of the scope of evaluation, the product or category name, and a control number
assigned by UL.
