26、rds Association (CSA) develops standards under the name Canadian StandardsAssociation, and provides certification and testing under the name CSA International. CSA Internationalprovides certification services for manufacturers who, under license from CSA, wish to use theappropriate registered CSA Ma
27、rks on certain products of their manufacture to indicate conformity withCSA Standards.CSA Certification for a number of products is provided in the interest of maintaining agreed-uponstandards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable,certification m
