What is UL 61058-2-93-2020 ?

Title: A Comprehensive Guide to UL 61058-2-93:2020 and UL 964-2020

When it comes to the safety and reliability of household appliances, two technical standards come into play: UL 61058-2-93:2020 and UL 964-2020. While both of these standards are essential for ensuring the proper functioning and performance of electrical appliances, they serve different purposes and have distinct requirements. In this article, we will provide a comprehensive overview of both standards, their significance, and how they relate to the world of appliance manufacturing.

UL 61058-2-93:2020: The Technical Standard for Switches in Appliances

UL 61058-2-93:2020 is a technical standard that pertains to switches used in appliances. It sets forth various safety requirements for these switches, focusing on ensuring the proper functioning and safe operation. By adhering to the requirements outlined in UL 61058-2-93:2020, manufacturers can develop appliances that meet high safety standards and minimize potential risks for consumers.

The standard covers various aspects of switch design, including electrical requirements, mechanical requirements, and environmental requirements. It also specifies requirements for labeling, marking, and documentation, which helps consumers make informed decisions when purchasing appliances.

Key Requirements of UL 61058-2-93:2020:

To ensure that a switch meets the requirements outlined in UL 61058-2-93:2020, manufacturers must conduct thorough testing and inspections of their products. This testing includes measuring various electrical and mechanical properties of the switch, as well as testing its performance in various environmental conditions.

To begin with, switches must undergo electrical tests to ensure that they can handle the maximum current draw of the appliance they are connected to. These tests are typically conducted using a specialized device called a "load switch" that simulates the maximum current draw of the appliance.

Meanwhile, mechanical tests are conducted to ensure that the switch operates correctly and that it is securely mounted to the appliance. These tests include tests for the switch's mechanical resistance, its mechanical continuity, and its mechanical tightness.

In addition to these tests, environmental tests are also conducted to ensure that the switch can withstand the various environmental conditions that it will be subjected to. For example, if the switch is designed to be installed in an oven, it must be able to withstand the high temperatures and humidity that an oven can generate.

UL 964-2020: The Technical Standard for Electrical Appliances and Equipment

UL 964-2020 is a technical standard that is essential for ensuring the safety and reliability of electrical appliances and equipment. It provides guidelines and requirements for the construction, performance, and testing of these products. By following the guidelines outlined in UL 964-2020, manufacturers can develop appliances that meet safety standards and are reliable and efficient.

The standard covers various aspects of electrical appliance design, including electrical requirements, environmental requirements, and performance requirements. It also specifies requirements for labeling, marking, and documentation, which helps consumers make informed decisions when purchasing electrical devices.

Key Components of UL 964-2020:

To ensure that an appliance meets the requirements outlined in UL 964-2020, manufacturers must conduct thorough testing and inspections of their products. This testing includes measuring various electrical and mechanical properties of the appliance, as well as testing its performance in various environmental conditions.

To begin with, electrical appliances must undergo electrical tests to ensure that they can handle the maximum current draw of the appliance they are connected to. These tests are typically conducted using a specialized device called a "load switch" that simulates the maximum current draw of the appliance.

Meanwhile, environmental tests are conducted to ensure that the appliance can withstand the various environmental conditions that it will be subjected to.
