What is UL 1959?

UL 1959 is a technical standard established by Underwriters Laboratories (UL), an independent safety certification organization. It applies to power-operated dispensing devices for motor fuels, such as gasoline and diesel. The purpose of UL 1959 is to ensure the safety and reliability of these devices, preventing accidents and protecting both consumers and properties.

Why is UL 1959 important?

UL 1959 plays a crucial role in the fuel dispensing industry. Compliance with this standard ensures that dispensing devices meet certain safety requirements, reducing the risk of fires, explosions, and other hazardous situations. By adhering to UL 1959, manufacturers can demonstrate their commitment to producing safe and reliable equipment, giving consumers peace of mind when refueling their vehicles.

Main requirements of UL 1959

UL 1959 covers a wide range of aspects related to fuel dispensing devices. Some of the main requirements include:

Safety features: The standard specifies the design and installation of safety features, such as emergency stop buttons, anti-pinch mechanisms, and automatic shut-off systems.

Electrical and mechanical components: UL 1959 sets stringent criteria for electrical wiring, grounding, and mechanical integrity. It ensures that materials used are suitable for the intended purpose and can withstand environmental conditions.

Compatibility with fuel types: The standard addresses compatibility issues with different types of fuels, ensuring that dispensing devices are designed to handle specific fuel properties and prevent fuel contamination.

How is compliance with UL 1959 determined?

Compliance with UL 1959 is determined through the rigorous testing and evaluation of dispensing devices. UL conducts various performance tests, inspecting critical components and assessing their ability to withstand extreme conditions. Manufacturers must also demonstrate proper documentation and compliance with applicable regulations.

In addition to initial testing, UL may conduct follow-up assessments and unannounced inspections to verify ongoing compliance. This continuous monitoring helps ensure that safety standards are maintained throughout the life cycle of the equipment.

By adhering to UL 1959, manufacturers, businesses, and end users can have confidence in the safety and reliability of fuel dispensing devices. Understanding the importance of this standard is crucial for anyone involved in the design, production, installation, and use of such equipment.
