Title: What is UL 60335-2-218 and UL 60335-2-373? A Guide to Safety Standards for Electrical Tools and Appliances

When it comes to the safety of our electrical tools and appliances, we want to ensure that they are reliable, safe, and meet the requirements of various safety standards. The Underwriters Laboratories (UL) is a non-profit organization that develops and maintains safety standards for a wide range of products, including electrical tools and appliances. In this article, we will discuss UL 60335-2-218 and UL 60335-2-373, two important safety standards for motor-operated handheld and transportable electric tools, and what they require.

What is UL 60335-2-218?

UL 60335-2-218 is a safety standard developed by UL specifically for the construction, marking, and testing of motor-operated handheld and transportable electric tools. This standard focuses on the requirements for these tools to minimize the risk of electrical shock, fire, and other hazards associated with their use. The main purpose of UL 60335-2-218 is to ensure that these tools are safe for use by consumers and professionals alike.

Key Requirements of UL 60335-2-218:

UL 60335-2-218 sets out several key requirements for the construction, marking, and testing of motor-operated handheld and transportable electric tools. These requirements include:

* The tools must have an internal overcurrent protection device (ICP) that can detect and interrupt the flow of current in the event of an overcurrent.

* The tools must also have a grounding feature that can provide a return path for the current in the event of a grounding failure.

* The tools must have a weatherproof enclosure that can withstand exposure to the elements, such as rain, snow, and moisture.

* The tools must also have a user-operable activation switch that can be easily turned on and off.

* The tools must have a label or tag that includes the name and rating of the tool, as well as any other relevant information.

* The tools must also have a serial number or batch number that can be used to identify them and track their use.

What is UL 60335-2-373?

UL 60335-2-373 is a safety standard developed by UL specifically for commercial electric cooking appliances, such as ovens, ranges, and grills. This standard applies to these appliances and sets out requirements to ensure their safe operation, such as:

* The appliances must have an automatic shut-off feature that can be easily turned on and off.

* The appliances must also have a heat-resistance feature that can withstand exposure to high temperatures.

* The appliances must have a grounding feature that can provide a return path for the current in the event of a grounding failure.

* The appliances must also have a user-operable activation switch that can be easily turned on and off.

* The appliances must have a label or tag that includes the name and rating of the appliance, as well as any other relevant information.

* The appliances must also have a serial number or batch number that can be used to identify them and track their use.

Conclusion:

UL 60335-2-218 and UL 60335-2-373 are important safety standards for motor-operated handheld and transportable electric tools and appliances, respectively. These standards are developed by UL to ensure that these tools and appliances are safe for use by consumers and professionals alike, and are subject to strict requirements that minimize the risk of accidents, injuries, and fires. By following the guidelines set out in these standards, we can ensure that we are using safe and reliable tools and appliances for our daily lives.
