What is UL 955?

UL 955 is a standard that pertains to the safety requirements for commercial refrigerators and freezers. It covers various aspects such as electrical, mechanical, and structural requirements to ensure that these appliances are safe to use and meet certain quality standards.

Electrical Safety

Under UL 955, commercial refrigerators and freezers must comply with specific electrical safety standards. This includes proper insulation of electrical components, protection against electric shock, and prevention of overheating. Testing and certification procedures are carried out to ensure that these appliances meet the necessary electrical safety requirements.

Mechanical Safety

The mechanical safety requirements outlined in UL 955 aim to prevent injury and accidents caused by moving parts or improper use of the appliance. This includes ensuring that doors and hinges are sturdy and well-designed, mechanisms for defrosting and temperature control operate correctly, and safety measures are in place to prevent entrapment of fingers or other objects in the appliance.

Structural Safety

Structural safety requirements address the overall construction and stability of commercial refrigerators and freezers. The standard specifies criteria for load-bearing capacity, secure mounting, and resistance to leakage or rupture. These measures help prevent accidents such as collapsing shelves, toppling appliances, or release of hazardous substances.

UL 955 provides manufacturers, retailers, and consumers with a reliable way to assess the safety and quality of commercial refrigerators and freezers. By adhering to this standard, manufacturers can ensure that their products are safe for use, while retailers and consumers can have confidence in the safety and performance of the appliances they purchase.

In conclusion, UL 955 is a crucial standard in the realm of commercial refrigeration. Its implementation ensures that electrical, mechanical, and structural safety requirements are met, providing peace of mind for both manufacturers and consumers. By complying with UL 955, the industry can maintain high-quality standards and reduce the risk of accidents or injuries related to commercial refrigerators and freezers.
