About CSA and UL
CSA (Canadian Standards Association also known as CSA Group) was established in
1919 as an independent testing laboratory in Canada. CSA received its recognition as an
NRTL (Nationally Recognized Testing Laboratory) in 1992 from OSHA (Occupational Safety
and Health Administration) in the United States of America (Docket No. NRTL-2-92).
When these marks appear with the indicator “C and US” it means that the
product is certified for both the US and Canadian markets, to the applicable US and
Canadian standards. (1)
As part of the reciprocal, US/Canvada agreement regarding testing laboratories, the
Standards Council of Canada (Canada’s national accreditation body) granted Underwrit-
ers Laboratories (UL) authority to certify products for sale in Canada. (2)
Only Underwriters Laboratories may grant a licence for the use of this mark, which indi-
cates compliance with both Canadian and US requirements. (3)
NRTLs Capabilities
NRTLs are third party organizations recognized by OSHA, US Department of Labor,
under the NRTL program.
The testing and certifications are based on product safety standards developed by US
based standards developing organizations and are often issued by the American National
Standards Institute (ANSI). (4)
The NRTL determines that a product meets the requirements of an appropriate consen-
sus-based product safety standard either by successfully testing the product itself, or by
verifying that a contract laboratory has done so, and the NRTL certifies that the product
meets the requirements of the product safety standard. (4)
Governance of NRTL
The NRTL Program is both national and international in scope
with foreign labs permitted.
