What is UL 60335-2-417?

The UL 60335-2-417 is a specific safety standard for household and similar electrical appliances, titled "Particular Requirements for Electrically Operated Hand-held Tools, Transportable Tools and Lawn and Garden Machinery - Safety." This standard is published by Underwriters Laboratories (UL), one of the leading testing and certification organizations worldwide. UL 60335-2-417 sets out the safety requirements and test methods that these types of tools and machinery must comply with in order to ensure consumer protection.

Importance of UL 60335-2-417

UL 60335-2-417 is essential for manufacturers, regulators, retailers, and consumers because it guarantees compliance with safety industry standards. Without adherence to such standards, there could be significant risks associated with using hand-held tools, transportable tools, and lawn and garden machinery. These appliances are often powered by electricity and pose potential hazards, including electric shock, fire, and other malfunctions. By following UL 60335-2-417 requirements, manufacturers can minimize these risks, ensuring their products are safe for consumers to use.

Requirements of UL 60335-2-417

UL 60335-2-417 covers various aspects related to the design, construction, and testing of tools and machinery. Some of the key requirements include:

Protection against electric shock: The standard specifies measures to prevent users from being electrocuted during normal operation, such as insulation, grounding, and double insulation.

Protection against mechanical hazards: It addresses the risks associated with moving parts, sharp edges, and flying debris, ensuring user safety while operating the equipment.

Protection against fire hazards: UL 60335-2-417 sets requirements for preventing or limiting the risk of fire-related incidents caused by electrical components or flammable materials.

Protection against thermal hazards: It establishes criteria to avoid overheating, both in the equipment and its surroundings, reducing the risk of burns or fire.

Instructions for safe operation and maintenance: The standard mandates clear and comprehensive user instructions to promote safe practices during tool operation, maintenance, and storage.

Compliance and Certification

To demonstrate compliance with UL 60335-2-417, manufacturers must undergo testing procedures conducted by accredited laboratories. These tests evaluate factors such as electrical insulation resistance, durability, performance under abnormal conditions, and temperature limits. Once the products pass the tests and meet all the necessary requirements, they receive UL certification, which attests their conformity to safety standards. Consumers can look for the UL mark on hand-held tools, transportable tools, and lawn and garden machinery to identify products that have undergone and met these rigorous safety evaluations.
