What is UL 60335-2-373?

UL 60335-2-373 is a safety standard established by Underwriters Laboratories (UL) for electrical appliances that are used in professional and commercial settings. This standard specifically focuses on the safety requirements for battery-powered devices and their associated charging systems. It covers a wide range of products, including industrial machinery, power tools, and equipment used in healthcare facilities.

Importance of UL 60335-2-373

Compliance with UL 60335-2-373 is crucial for manufacturers and users of professional electrical appliances. By adhering to this standard, manufacturers can ensure that their products are designed and built to meet rigorous safety requirements. This includes protection against risks such as electric shock, fires, and other potential hazards. For users, UL 60335-2-373 certification provides confidence in the safety and reliability of the appliances they use in their workplaces.

Key Requirements

UL 60335-2-373 sets forth specific requirements that need to be met for an appliance to be deemed safe for professional use. These include provisions for insulation, grounding, appropriate labeling, protection against overheating, and adequate safeguards for the charging systems. It also details guidelines related to maintenance, user instructions, and the provision of adequate technical documentation. Manufacturers must undergo rigorous testing and evaluation processes to obtain certification for their products.

The Certification Process

To obtain certification under UL 60335-2-373, manufacturers need to submit their products for testing to a certified laboratory. The laboratory performs various tests to evaluate the compliance of the appliance with the standard's requirements. These tests may include electrical safety tests, thermal testing, impact assessments, and evaluations of the charging systems. If the product successfully meets all the criteria, it is granted UL 60335-2-373 certification, and the manufacturer can affix the appropriate markings on their appliances.
