Canadian Standards Association
From Free net encyclopedia
Image:CSA c-us.png Established in 1919, the Canadian Standards Association (CSA) is a world leader in safety standards testings. The CSA is a division of the CSA Group. Its mark appears on over one billion products sold annually, and tells consumers that the product meets or surpasses its strict standards for safety and performance.
CSA will generally approve a product based on a sample and a copy of a test report from Underwriters Laboratories, its US counterpart, whereas UL will always perform testing itself at the manufacturer's expense. Because of this, and because many companies wish to sell to the entire North American market, it is common for a manufacturer to obtain UL approval first, then submit a sample product with the UL report to CSA; therefore many products sold in North America will bear both UL and CSA logos.
