What is UL 60335-2-358 ?

Title: Understanding UL 60335-2-358 and 60335-2-360: Safety Standards for Flammable Refrigerants

Appliances are an essential part of our daily lives, and the use of flammable refrigerants can pose significant safety risks. To address these concerns, Underwriters Laboratories (UL) has developed two safety standards, UL 60335-2-358 and UL 60335-2-360, to ensure the safe operation of appliances using these refrigerants. In this article, we will delve into the technical aspects of these standards and their significance in ensuring appliance safety.

Purpose of UL 60335-2-358 and 60335-2-360:

UL 60335-2-358 and 60335-2-360 are safety standards developed by UL to address the unique challenges associated with appliances using flammable refrigerants. The primary objective of these standards is to minimize the potential risks associated with the use of these refrigerants and ensure the safe operation of appliances. These standards cover the entire lifecycle of the appliance, from design and production to installation and use.

Key Requirements of UL 60335-2-358 and 60335-2-360:

UL 60335-2-358 and 60335-2-360 define specific criteria that manufacturers must meet during the design, production, and testing process to minimize potential hazards associated with the use of flammable refrigerants. These requirements include:

Material selection: The use of fire-resistant materials for the enclosure, components, and fasteners.

Electrical requirements: The use of non-flammable materials for electrical components and wiring.

Fire-resistant mechanisms: The inclusion of fire-resistant mechanisms, such as fire-resistant hinges and door locks.

Pressure relief: The use of pressure relief valves to release pressure in the event of a leak or rupture.
