Underwriters Laboratories Inc. (UL) is an independent product safety certification organization based in the United States. It develops safety standards and conducts testing on materials, products, buildings, facilities, processes, and systems to ensure their reliability.
UL evaluates various sectors, including building materials, energy, fire protection systems, lighting, plastic components, wire and cable systems, plumbing products, and water system components, assessing them for risks related to electricity, fire, and injury.
Since its founding in 1894, UL has approved approximately 20 billion products, developed over 1,600 standards, and assessed more than 96,000 products. The organization operates in 104 countries with 170 laboratories, providing testing and certification services worldwide.
UL’s official website (www.ul.com) offers access to the UL Directory, which provides comprehensive listings of UL-certified products and their manufacturers.
What is UL 448 Standard?
The UL 448 standard defines the design and testing requirements for pumps used in fire protection systems. It is based on the NFPA 20 “Installation of Pumps for Fire Protection” standard but has some distinct requirements.
UL 448 mainly focuses on the hydraulic aspects of the pump. Fire pumps must be manufactured and supplied with the following UL-listed equipment:
- UL-Listed Fire Pump
- UL-Listed Electric Motor Compliant with NEMA-MG1 Standard
- UL-Listed Diesel Engine
- UL-Listed Electric Fire Pump Control Panel
- UL-Listed Diesel Fire Pump Control Panel
- UL-Listed Jockey Pump Control Panel
- UL-Listed Casing Relief Valve (for Electric Pumps)
- UL-Listed Air Release Valve
- Fuel Tank Manufactured per UL 142 Standard
