What is UL 60335-2-24?

The UL 60335-2-24 is a technical standard set by Underwriters Laboratories (UL) that specifically pertains to the safety requirements for refrigerating appliances and ice-makers. This standard focuses on the protection against hazards related to refrigerant leaks. It provides guidelines and test procedures that manufacturers must comply with in order to ensure the safe use of these appliances.

The Purpose of UL 60335-2-24

The main purpose of UL 60335-2-24 is to prevent any potential risks or accidents caused by refrigerant leakage in refrigerating appliances and ice-makers. Refrigerants, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), can pose serious threats to human health and the environment if not properly contained or handled. This standard aims to minimize the impact of refrigerant leaks by setting requirements for design, construction, and testing of these appliances.

Key Requirements of UL 60335-2-24

UL 60335-2-24 establishes various requirements that manufacturers must adhere to when producing refrigerating appliances and ice-makers. These include:

Leakage detection: The standard mandates the inclusion of effective means to detect refrigerant leaks, such as sensors or indicators, to provide timely warnings to users.

Containment and evacuation: Appliances must be designed to ensure proper containment of refrigerants and allow for their safe removal during servicing or disposal.

Electrical safety: UL 60335-2-24 also covers electrical safety aspects, including insulation, grounding, and protection against electric shock.

Performance and reliability: The standard sets specifications for the performance and reliability of refrigerating appliances, ensuring they operate efficiently and durably.

Compliance and Certification

Manufacturers who wish to market their refrigerating appliances and ice-makers in regions where UL 60335-2-24 is recognized as a safety standard must ensure their products comply with its requirements. Compliance is typically verified through testing conducted by UL or other approved testing laboratories. Once a product successfully meets the requirements, it can receive UL certification, which signifies its compliance with this standard.
