UL, CSA, ETL & CE FACT SHEET
Marra Forni products that feature these logos meet
rigorous standards for electrical safety and electro-
magnetic emissions. The acronyms are as follows:
UL: Underwriters Laboratories, Inc.
CSA: Canadian Standards Association
ETL: Formerly ETL Testing Laboratories, now Inter-
tek Testing Services
CE: Conformance European
Underwriters Laboratories, Inc. is an independent
nonprot organization that tests products for safety
and certies them. UL has developed more than
800 standards for safety, and millions of products
and their components are tested to UL’s safety
standards. If a Marra Forni product is UL listed, you
know it has passed UL’s stringent tests for electrical
safety. UL’s web site can be found at http://www.
ul.com.
The Canadian Standards Association is a nonprot
association serving business, industry, government
and consumers in Canada as well as the global
marketplace. Along with their other duties, CSA
develops standards that enhance public safety. A
Nationally Recognized Testing Laboratory (NRTL),
CSA also familiarizes themselves with U.S. require-
ments. According to OSHA regulations, the CSA-US
mark qualies as an alternative to the UL mark.
The ETL mark is an alternative to both the CSA and
UL marks.
Intertek Testing Services, formerly known as ETL,
has been conducting electrical performance and re-
liability tests since 1896. Intertek Testing Services
acquired ETL in 1996. ITS is recognized by OSHA
as a Nationally Recognized Testing Laboratory, just
like UL, CSA and several other independent organi-
zations. ITS tests products according to nearly 200
safety and performance standards. The ETL listed
mark and C-ETL listed mark are accepted through-
out the U.S. and Canada when denoting compliance
with nationally recognized standards such as ANSI,
IEC, UL and CSA. This mark indicates that the prod-
uct has been tested to and has met the minimum
requirements of a widely recognized (concensus)
U.S. product safety standard, that the manufactur-
ing site has been audited, and that the applicant
has agreed to a program of periodic factory follow-
up inspections to verify continued conformance.
If the mark includes a small “US” or “C,” it follows
product safety standards of the United States and/
or Canada, respectively.
The European Commission describes the CE mark
as a “passport” that allows manufacturers to cir-
culate industrial products freely within the internal
market of the European Union. The CE mark certi-
es that the products have met E.U. health, safety
and environmental requirements that ensure work-
place and consumer safety. All manufacturers in
the E.U. and abroad must afx the CE mark to those
products covered by the “New Approach” directives
in order to market their products in Europe. Once
a product receives the CE mark, it can be marketed
throughout the E.U. without undergoing further
modication. An important document related to
CE is the Declaration of Conformity (DOC). It is a
statement that a company authority must sign to
say that their device meets the requirements of the
directive. The DOC must include a list of any stan-
dards used to justify the claim of compliance with
the directive.
If a Marra Forni product is stamped “CE,” the prod-
uct does not emit excessive radiation (microwave
or RF), and is not overly sensitive to picking up
radiation. In summary, the certication marks on
our products are your assurance that the product
meets rigorous standards for electrical safety and
electromagnetic emissions. It poses no shock
hazard (except as noted on the product or manual),
and it will not cause EM interference with other
devices beyond a certain distance.
