While UL does not have the authority to approve or reject a product for production, many governmental agencies, including federal, state, and local authorities, require UL testing as a prerequisite for official approval. These agencies may have their own specific standards and regulations, such as municipal building codes, which necessitate UL testing to ensure compliance.
