Title: What is UL 60335-2-328 and UL 60335-2-298? A Guide to Safety Standards for Battery-Powered Tools

When it comes to power tools and electrically operated gardening appliances, safety is a top priority. The use of batteries to operate these tools can pose a significant risk of electrical shocks, fire hazards, and other potential dangers. To mitigate these risks, Underwriters Laboratories (UL) has established technical standards for the safety of battery-powered tools. In this article, we will discuss UL 60335-2-328 and UL 60335-2-298, two important safety standards for battery-operated tools.

Understanding UL 60335-2-328 and UL 60335-2-298:

UL 60335-2-328 is a technical standard developed by UL that specifically addresses the safety requirements for battery-powered tools and similar electrically operated gardening appliances. This standard provides guidelines for manufacturers to ensure the safety of these products for both consumers and professionals. The main purpose of UL 60335-2-328 is to reduce the risk of electrical shocks, fire hazards, and other potential dangers associated with battery-operated tools used in gardens and outdoor areas.

UL 60335-2-298 is an international safety standard that specifically applies to motor-operated hand-held tools and household and similar electrical appliances. It outlines the requirements for the design, construction, and testing of these devices to ensure their safe use. The purpose of UL 60335-2-298 is to establish safety guidelines for motor-operated hand-held tools and household appliances to prevent potential hazards that could result in injury or property damage.

Key Safety Requirements:

Both UL 60335-2-328 and UL 60335-2-298 provide specific requirements for manufacturers to ensure the safety of their battery-operated tools. Key safety requirements for both standards include:

Electrical insulation: Manufacturers must ensure that their products have adequate electrical insulation to prevent electrical hazards.

Grounding: Manufacturers must ensure that their products are properly grounded to prevent electrical hazards.

Temperature limitations: Manufacturers must ensure that their products are not operated at temperatures that could cause damage or pose a fire hazard.

Mechanical strength: Manufacturers must ensure that their products are designed and constructed to withstand the expected loads and stresses.

Protection against moisture and dust ingress: Manufacturers must ensure that their products are designed to prevent moisture and dust from entering the electrical components, which can cause damage and pose a fire hazard.

Conclusion:

UL 60335-2-328 and UL 60335-2-298 are important safety standards for battery-operated tools. They provide manufacturers with specific requirements to ensure the safety of their products, which can help prevent electrical shocks, fire hazards, and other potential dangers associated with the use of batteries. By following these standards, manufacturers can create products that are safe and reliable for both consumers and professionals.
