About CSA and NRTL
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 certified 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 certi-
fied to CSA C22.2 No. 60950-1 (2nd Ed) and UL 60950-1 (2nd Ed). Alpha UPS products, bear-
ing 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 Underwriters Laboratories may grant a licence for the use of this mark, which indicates
compliance with both Canadian and US requirements. (3)
NRTLs capabilities
NRTLs are third party organizations recognized by OSHA, US Depart-
ment 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 ap-
propriate consensus-based product safety standard either by success-
fully testing the product itself, or by verifying 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.
