It is a not-for-profit, nonstatutoiy, voluntary membership association engaged in stan

CSA standards reflect a national consensus of produc- ers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adop
35、ted by mu- nicipal, provincial, and federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Can- ada indicate their support for CSAs standards develop- ment by volunteering

The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and con- t

In addition to its head office and laboratory complex in Rexdale (Toronto), CSA has regional branch offices in majorcentres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the
