Attachment What Are The UL And FM?⸺

-What is UL? 

 

UL (Underwrites Laboratories / Insurance Laboratory) is an independent certification body that sets product safety standards and tests the safety of products under these standards. UL has certified over 19,000 products. More than 20 million UL products manufactured by 7,200 factories worldwide are used every year. The UL has 64 testing laboratories in 98 countries, providing testing and certification services to its customers. UL has standards in many areas, such as building materials, food, lighting and fire protection systems.

UL is dedicated to product testing and reliability for 100 years. UL testing and certification services provide advantages to manufacturers and users of fireproof systems.⸺

 

–what is FM?

 

FM (Factory Mutual / Factory Mutual) is an independent technical organization providing performance certification for the materials and systems of FM (I Factory Mutual Insurance / Factory Mutual Insurance) for private and high risk insurance.

The FM certification of fire pump is carried out according to the requirements of NFPA 20, but the FM certification also pursues some requirements other than NFPA 20, which is called the highest level of product quality certification, which is the most difficult certification method.

 

The flow requirements for fire pumps are listed in the following table:
