CSA is proud to be a Nationally Recognized Testing Laboratory (NRTL) by the U.S. Occupational Safety and Health Administration (OSHA). That means they test and certify your products to U.S. as well as Canadian standards, and you can be sure that your certification will be recognized by federal, state, provincial, and local authorities. They work with manufacturers to help them understand the certification requirements of their chosen markets. They test products and systems to ensure they meet CSA International or other recognized North American or international standards. CSA International certification tells you that a product or system has been evaluated under a formal process that includes examination, testing, and follow-up inspection-and that the product complies with all applicable standards.
