What is UL 60335-2-364 ?

Title: Understanding UL 60335-2-364 and UL 60335-2-373: Ensuring Safe Operation of Refrigerant-Containing Appliances

Introduction:

When it comes to the safety of our appliances, we want to ensure that they are functioning as intended. One of the most critical aspects of appliance safety is the use of flammable refrigerants. These apps have the potential to pose a serious fire hazard if not handled properly. To address this challenge, Underwriters Laboratories (UL) has developed two safety standards: UL 60335-2-360 and UL 60335-2-373. In this article, we will delve into the technical aspects of these standards and their significance in ensuring appliance safety.

UL 60335-2-360: Understanding the Standard

UL 60335-2-360 is a set of safety standards developed by UL for appliances using flammable refrigerants. The primary objective of this standard is to address the unique challenges associated with these appliances, including their high-temperature operating conditions, heavy loads, and demanding operating conditions.

To ensure the safety of these appliances, UL 60335-2-360 sets forth specific requirements and tests to verify their safe operation. These requirements cover various aspects of the appliance's design, production, installation, and use. Compliance with the standard is mandatory for manufacturers to ensure that their products are safe to operate and pose minimal risk of fire or explosion.

Key Requirements of UL 60335-2-360

Compliance with UL 60335-2-360 is achieved by meeting various requirements established by UL. These requirements are divided into several categories, including:

1. Electrical Safety: This category encompasses the electrical safety requirements for the appliance, including the use of insulated wiring, grounding, and labeling.

2. Fire Prevention: This category includes the fire prevention requirements for the appliance, such as fire-resistant materials, fire alarms, and fire-resistant paths.

3. Electrical Performance: This category pertains to the electrical performance requirements for the appliance, including the use of appropriate voltage levels, current ratings, and grounding.

4. Physical Safety: This category covers the physical safety requirements for the appliance, including the use of appropriate materials, dimensions, and weight limits.

5. Use and Installation: This category outlines the use and installation requirements for the appliance, including the requirements for proper usage, maintenance, and repair.

UL 60335-2-373: Understanding the Standard

UL 60335-2-373 is a safety standard specifically developed for commercial electric cooking appliances. It sets out requirements to ensure the safe operation of these appliances and minimize the potential risks associated with their use.

The primary objective of UL 60335-2-373 is to reduce the risks associated with the use of commercial electric cooking appliances in professional kitchens. This includes ensuring that the appliances are safe to operate at high temperatures, under heavy loads, and in demanding operating conditions.

Key Requirements of UL 60335-2-373

Compliance with UL 60335-2-373 is achieved by meeting various requirements established by UL. These requirements are divided into several categories, including:

1. Electrical Safety: This category encompasses the electrical safety requirements for the appliance, including the use of insulated wiring, grounding, and labeling.

2. Fire Prevention: This category includes the fire prevention requirements for the appliance, such as fire-resistant materials, fire alarms, and fire-resistant paths.

3. Electrical Performance: This category pertains to the electrical performance requirements for the appliance, including the use of appropriate voltage levels, current.
