This is one
of the most common Underwriters Laboratories marks. If a product
carries this mark, it means UL found that samples of this product
met its safety requirements. These requirements are primarily based
on ULs own published Standards for Safety.
Consumers rarely see this mark, because
it is for components that are part of a larger product or system.
These components may have restrictions on their performance or may
be incomplete in construction. The Component Recognition marking
is found on a wide range of products, including some switches, power
supplies, printed wiring boards, some kinds of industrial control
equipment and thousands of other products.
The UL Recognized Component Mark, for
components certified by UL to meet both Canadian and U.S. requirements,
became effective in 1998. Although UL had not originally planned
to introduce a combined Recognized Component Mark, the popularity
of the Canada/U.S. Listing and Classification Marks among clients
with UL certifications for both countries has led to the new mark.
This is one of the most common Canadian
Standards Association (CSA) marks. If a product carries this mark,
it means CSA found that samples of this product met its safety requirements.
These requirements are primarily based on CSAs own published
Standards for Safety.
