What is UL 60335-2-71

UL 60335-2-71 is a standard that focuses on the safety requirements for electrical appliances that are intended for household and similar use. This standard is a part of the broader UL 60335 series which covers various aspects of appliance safety.

Scope and Application

The scope of UL 60335-2-71 includes electrical appliances such as refrigerators, freezers, ice makers, and similar equipment. It also applies to certain components and accessories used in these appliances. The standard provides guidelines and test methods to ensure the safe design, construction, and operation of these appliances.

This standard is applicable to manufacturers, testing laboratories, and regulatory bodies involved in the development, production, testing, and certification of electrical appliances. Compliance with UL 60335-2-71 is essential for ensuring the safety of these appliances before they are marketed and used by consumers.

Key Safety Requirements

UL 60335-2-71 specifies several safety requirements that appliances must meet in order to comply with the standard. These requirements cover aspects such as electrical insulation, protection against electric shock, temperature limits, mechanical strength, marking and instructions, and more.

For example, the standard requires that the electrical insulation of the appliances is sufficient to prevent electric shock under normal operating conditions. It also sets temperature limits for different parts of the appliances to ensure they do not overheat and pose a risk of fire or damage. Additionally, the standard addresses the mechanical strength of the appliances to ensure they can withstand normal use without causing injury.

Compliance and Certification

Manufacturers must ensure their appliances comply with the safety requirements outlined in UL 60335-2-71. This involves conducting tests and evaluations to verify that the appliances meet the necessary criteria. Testing may include electrical performance, temperature rise, mechanical strength, and more.

Once a manufacturer has established compliance, they can seek certification from a recognized regulatory body or testing laboratory. Certification ensures that the appliances have been thoroughly evaluated and deemed safe for use. Consumers can look for the UL mark or other relevant certifications to ensure they are purchasing appliances that meet safety standards.
