Certification
CSA (Canadian Standards Association also known as CSA International) 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). This was expanded and renewed in 1997,
1999, and 2001. The specific notifications were posted on OSHA’s official website as follows:
•
Federal Register #: 59:40602 - 40609 [08/09/1994]
•
Federal Register #: 64:60240 - 60241 [11/04/1999]
•
Federal Register #: 66:35271 - 35278 [07/03/2001]
When these marks appear with the indicator “C and US” or “NRTL/C” it means that the product is certi-
fied for both the US and Canadian markets, to the applicable US and Canadian standards. (1)
Alpha rectifier and power system products, bearing the aforementioned CSA marks, are certified to CSA
C22.2 No. 60950-01 and UL 60950-1. Alpha UPS products, bearing the aforementioned CSA marks,
are certified to CSA C22.2 No. 107.3 and UL 1778. As part of the reciprocal, US/Canada agreement
regarding testing laboratories, the Standards Council of Canada (Canada’s national accreditation body)
granted Underwriters Laboratories (UL) authority to certify products for sale in Canada. (2) Only Under-
writers Laboratories may grant a license for the use of this mark, which indicates compliance with both
Canadian and US requirements.(3)
NRTL’s 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
consensus-based product safety standard either by successfully testing the product itself, or by veri-
fying that a contract laboratory has done so, and the NRTL certifies that the product meets the require-
ments of the product safety standard. (4)
Governance of NRTL
The NRTL Program is both national and international in scope with foreign labs permitted.
