Title: Understanding UL 60335-2-357 and UL 60335-2-373: Safety Standards for Air Conditioning and Heating Products

UL (Underwriters Laboratories) is a global organization that provides safety certification and testing services for a wide range of products, including appliances. Two of UL's standards that are particularly relevant to air conditioning and heating products are UL 60335-2-357 and UL 60335-2-37In this article, we will discuss the purpose of these standards, key requirements, and testing procedures.

What is UL 60335-2-357?

UL 60335-2-357 is a technical standard developed by UL that focuses on the safety requirements for appliances used in air conditioning, heating, and cooling systems. This standard specifically covers heat pumps, chillers, dehumidifiers, and air conditioners. The primary goal of UL 60335-2-357 is to ensure the safe operation of these appliances to protect both users and the environment.

The standard defines specific criteria that manufacturers must meet during the design, production, and testing process to minimize potential hazards. By adhering to the requirements outlined in UL 60335-2-357, manufacturers can demonstrate that their products are reliable, safe, and compliant with industry regulations.

Key Requirements and Testing Procedures:

UL 60335-2-357 outlines several key requirements and testing procedures to ensure the safety of the appliances. These requirements include:

Electrical Safety: The appliance must have an electrical circuit that is properly grounded and labeled.

Performance and Reliability: The appliance must be able to perform consistently and reliably over a long period of time.

Safety Protection: The appliance must have built-in safety features to protect users from electrical shock, fire, or other hazards.

: , , .Testing Procedures:

To ensure compliance with the requirements of UL 60335-2-357, manufacturers must conduct extensive testing procedures for their products. These procedures may include:

Electrical Testing: The appliance's electrical circuit must be tested to ensure that it is properly grounded and labeled.

Performance Testing: The appliance must be tested to ensure that it performs consistently and reliably over a long period of time.

Safety Testing: The appliance must be tested to ensure that it has built-in safety features to protect users from electrical shock, fire, or other hazards.

What is UL 60335-2-373?

UL 60335-2-373 is a safety standard developed by UL specifically for commercial electric cooking appliances. This standard sets out requirements to ensure the safe operation of commercial electric cooking appliances, including ovens, ranges, and grills.

The purpose of UL 60335-2-373 is to reduce the risks associated with the use of commercial electric cooking appliances in professional kitchens. These appliances are subject to high temperatures, heavy loads, and demanding operating conditions, so it's crucial to establish safety requirements that minimize the potential for accidents, injuries, or fires.

Key Requirements of UL 60335-2-373:

UL 60335-2-373 also outlines several key requirements to ensure the safety of commercial electric cooking appliances. These requirements include:

Electrical Safety: The appliance must have an electrical circuit that is properly grounded and labeled.

Performance and Reliability: The appliance must be able to perform consistently and reliably over a long period of time.

Safety Protection: The appliance must have built-in safety features to protect users from electrical shock, fire, or other hazards.

Fire Prevention: The appliance must have a fire prevention system to minimize the risk of fires.

Conclusion:

UL 60335-2-357 and UL 60335-2-373 are important safety standards that require manufacturers of air conditioning and heating products to meet specific requirements for their products. By adhering to these standards, manufacturers can demonstrate that their products are safe, reliable, and compliant with industry regulations.
