What is UL 60335-2-73 ?

Title: Understanding UL 60335-2-73: The Safety Standard for Electrical Appliances Near Water

When it comes to the safety of our electrical appliances, it is essential to have certifications that guarantee their reliability and quality. The United States of America has created the National Electrical Code (NEC) to ensure that all electrical products are safe for use. However, for appliances that are used in close proximity to water, the use of UL 60335-2-73 is mandatory. This standardized safety certification ensures that electrical appliances are safe to use in wet environments and minimize the risk of electric shock or other hazards.

What is UL 60335-2-73?

UL 60335-2-73 is a safety certification standard that applies to electrical appliances that are used in close proximity to water. It is specifically designed to address the requirements for UV irradiators and aims to minimize the risk of electric shock, fire, and injury caused by exposure to ultraviolet radiation.

The Purpose of UL 60335-2-73:

The main purpose of UL 60335-2-73 is to ensure the safe operation of UV irradiators, which are used in various applications such as water disinfection, air purification, and surface sterilization. These devices emit ultraviolet radiation and can pose potential risks if not designed, constructed, and tested properly. UL 60335-2-73 sets stringent requirements for UV irradiators, aiming to minimize the risk of electric shock, fire, and injury caused by exposure to ultraviolet radiation.

Key Requirements of UL 60335-2-73:

To obtain UL certification for their products, manufacturers must comply with the requirements outlined in UL 60335-2-7The standard has several key requirements that manufacturers must meet, including:

Reduced voltage: The appliance must have a reduced voltage rating that is equal to or lower than the maximum voltage level that the UV irradiator can operate on.

No contact with water: The appliance must be designed to prevent contact with water or moisture.

Electrical isolation: The appliance must be designed to prevent electrical currents from flowing from the UV irradiator to the user or other components.

Compliance with UL 60335-2-73: Manufacturers must ensure that their appliances comply with the requirements outlined in UL 60335-2-73, including the use of appropriate materials and the marking of the appliance with the UL certification symbol.

Conclusion:

UL 60335-2-73 is an essential safety standard that ensures that electrical appliances are safe to use in close proximity to water. By adhering to the requirements outlined in the standard, manufacturers can provide assurance to consumers and regulatory bodies that their products meet recognized safety standards. It is important to be aware of the requirements of UL 60335-2-73 to ensure the safety of our electrical appliances
