What is UL 60335-2

In the field of electrical appliances, safety and reliability are of paramount importance. Manufacturers and consumers alike rely on standardized testing protocols to ensure that products meet certain safety standards. One such standard is UL 60335-2, a globally recognized standard for the safety of household and similar electrical appliances.

Scope and Purpose

UL 60335-2 sets out specific requirements for the construction and performance of electrical appliances, including their components and materials. The standard covers a wide range of household appliances such as refrigerators, washing machines, vacuum cleaners, and cooking equipment. Its primary goal is to reduce the risk of fire, electric shock, and injury to users or bystanders by ensuring that these appliances are manufactured with adequate safeguards in place.

Key Requirements

UL 60335-2 specifies various technical requirements that manufacturers must comply with. For example, it includes guidelines for insulation resistance, protection against moisture ingress, mechanical strength, and temperature rise. The standard also addresses specific safety concerns related to the use of appliances, such as control devices, heating elements, and detachable power cords. Compliance with these requirements helps to ensure that appliances function safely and reliably throughout their lifespan.

Testing and Certification

Before an appliance can be sold in many countries, it must undergo rigorous testing to determine its compliance with UL 60335-2 and other applicable standards. Independent testing laboratories evaluate appliances based on established test procedures outlined in the standard. These tests may include checking for proper grounding, insulating properties, overcurrent protection, and more. Only appliances that pass these tests and meet the necessary criteria will receive UL certification, indicating that they meet the required safety standards.
