In the North American market, property damage and personal injury incidents caused by electric fan safety accidents have attracted consistent attention from all sectors every year. In 2023, a report released by the U.S. Consumer Product Safety Commission (CPSC) showed that there were 320 fire accidents caused solely by pedestal fan tipping and motor overheating, resulting in millions of dollars in economic losses. As the core standard regulating the safety of such products, ANSI/UL 507, Standard for Safety for Electric Fans, has undergone ten revisions since it was first approved in 1993 and has now become a mandatory technical threshold for electric fans to enter the North American market.

1. Overview and Scope of Application of UL507

UL507, whose full name is Standard for Safety for Air-Moving Equipment, is developed and maintained by Underwriters Laboratories (UL). This standard explicitly applies to various types of electric fan products with a rated voltage not exceeding 600 volts, covering a wide range of categories from household to industrial use, including: household pedestal fans, table fans, ceiling fans, attic fans, bathroom exhaust fans, kitchen range hoods, duct fans, low-voltage DC fans, and the increasingly popular neck-hung portable fans in recent years.

2. Core Safety Requirements and Technical Specifications of UL507

UL507 has established a comprehensive safety assessment system, which imposes strict requirements on fan products from four dimensions: electrical safety, mechanical structure, material performance, and environmental adaptability. The core goal of this system is to prevent potential hazards such as electric shock, fire, and mechanical injury, ensuring the safety of products during normal use and under abnormal operating conditions. PEGO’s equipment can meet the testing requirements of this standard, and the specific list of equipment is as follows:
