What is UL 87?

UL 87 is a technical standard that focuses on the safety and performance requirements for electric signs and displays. The standard is developed by Underwriters Laboratories (UL), a global independent safety science company. UL 87 provides guidelines and specifications for electrical and structural components used in signs, helping manufacturers ensure their products are safe and reliable.

Importance of UL 87

UL 87 plays a crucial role in promoting public safety and preventing potential hazards associated with electric signs. As signs usually involve electrical components like transformers, wiring, and lighting systems, it is essential to adhere to safety standards to minimize the risk of fires, shock, or other accidents. Compliance with UL 87 not only ensures the safety of customers and users but also protects manufacturers from liability issues.

Key Requirements of UL 87

UL 87 covers various aspects related to electric signs, including electrical systems, structural features, and performance criteria. Some key requirements specified by the standard include:

Electrical Wiring: The standard outlines the proper installation, sizing, insulation, and grounding of electrical wiring to prevent short circuits and electrical faults.

Lighting Systems: UL 87 sets parameters for lighting fixtures, ensuring optimal illumination without excessive heat generation or excessive energy consumption. It also specifies guidelines for emergency lighting and exit signs.

Environmental Considerations: The standard addresses factors such as outdoor exposure, temperature variations, and moisture resistance, making sure that signs can withstand different environmental conditions without compromising safety or performance.

Structural Integrity: UL 87 requires signs to be structurally stable, preventing issues like collapse or falling due to wind pressure, earthquakes, or other external forces. It specifies load considerations, anchoring methods, and material durability.

Conclusion

UL 87 is a technical standard that establishes safety and performance requirements for electric signs and displays. Compliance with this standard ensures that manufacturers produce safe and reliable products, minimizing the risk of accidents and enhancing public safety. By adhering to the guidelines outlined in UL 87, both manufacturers and users can have confidence in the quality and reliability of electric signs.
