UL has developed more than 1,300 safety standards. A typical standard for electrical products covers not only electrical safety requirements, but also a wide range of flammability and mechanical hazards. UL tests the organisation of products, components, materials and systems to see if they meet specific requirements. UL certification thus enables the export of products to the USA.

CSA stands for "Canadian Standards Association" and is an independent, non-governmental organisation for product testing and certification. In accordance with the regulations of the us Occupational Safety and Health Administration, CSA is a qualified alternative to UL certification and thus also enables the export of products to the USA. CSA-certified products are also characterised by high product quality.
