CANADIAN STANDARD AGENCIES

CSA STANDARDS

The Canadian Standards Association is an organization that admin-
isters and coordinates the standardization system in Canada. Cross-
certification between the U.S. and Canada has been granted, based on 
the Mutual Recognition Agreement (MRA).
Electrical appliances connected to a public power source in Canada 
must conform to CSA Standards. Manufacturers of these products need 
to obtain C-UL or CSA certification, or the seller needs to apply for cer-
tification directly to the provincial authorities.
For more details on the CSA Standards, please visit the CSA website.

INTERNATIONAL STANDARD AGENCIES

International standards also play a significant role in North American 
machine safety. The two main international entities are the Internation-
al Electrotechnical Committee (IEC) and the International Standards 
Organization (ISO). IEC is a recognized provider of standards in the 
electrotechnical field and is composed of national electrotechnical com-
mittees. ISO is an international federation of national standardization 
bodies. ISO and IEC influence international standards through formal 
relationships. In the US, ANSI coordinates with ISO and IEC through 
technical advisory groups (TAG).
