Electric Sign Certification and Sign Component Solutions

Testing and certification solutions for electric sign and sign component manufacturers

UL Solutions offers technical leadership in the electric signs industry, staying at the forefront of emerging standards, requirements and regulations for digital signs, electric signs, and sign retrofit kits and components.

We provide comprehensive testing, certification and professional training in engineering best practices and regulatory standards. Our services are tailored for manufacturers of electric signs that require building inspector approval under the National Electrical Code® NFPA 70®, Article 600. This includes LED displays used for advertising, signs integrated with other equipment (such as gaming machines or gas pumps), and sign retrofit kits used to update the illumination technology or controls.

Common standards and requirements include:

• UL 48, the Standard for Electric Signs
• UL 879, the Standard for Electric Sign Components
• UL 879A, the Standard for LED Sign and Sign Retrofit Kits
• National Electrical Code®, ANSI/NFPA 70®, Article 600
• California Energy Commission (CEC) Title 24
• IECEE and CB Scheme for electric signs and sign components

General Coverage Program for UL 48

The UL Solutions General Coverage program provides sign manufacturers with extensive flexibility for certification of custom-made signs, including channel letters, box signs, awning signs, changing message signs and portable signs. Signs can be certified for dry, damp or wet location installation.

Our online electric sign registration portal simplifies the process and allows you to navigate from the application stage to the application of the UL Mark to your signs that meet compliance requirements.

The Sign Components database on UL Product iQ® (previously known as the Sign Component Manual or SAM) is designed to be a buyer’s guide for general coverage sign shops and designers. There, manufacturers can perform parametric searches to quickly identify components that can meet their specific design needs.

For large signs that do not fit under the UL 48 General Coverage program, UL Solutions offers preliminary investigations and on-site evaluations that create a pathway toward certification and official approval for a specific project.
