UL Standards are a set of safety and performance standards developed by Underwriters Laboratories (UL).

Founded in 1894, UL is a leading global safety science company headquartered in Illinois, USA.

UL standards are designed to ensure the safety, reliability and sustainability of products, materials, equipment and buildings through testing and certification.

UL standards are specifically categorized:

• Electrical Safety Standards: e.g. UL 62368-1 (Safety Requirements for Audio and Video Equipment), UL 2054 (Safety Standard for Household and Commercial Batteries), which are designed to protect against the risks of electric shock, short circuits, etc.
• Flammability standards: e.g. UL 94 (flammability testing of plastic materials), UL 340 (flammability testing of liquids), assessing the performance of materials in a fire.
• Sustainability standards: e.g. UL 110 (sustainability standard for cell phones), UL 172 (sustainability standard for toys), focusing on the environmental impact of products.
• Performance standards: e.g. UL 2596 (battery housing material performance test), UL 2802 (camera image quality test), to ensure that products function as expected.

UL Standards Application Areas:

• Electrical equipment: such as circuit breakers, switchgear, etc. UL 1558 standard and UL 1066 standard apply to metal-enclosed low-voltage power switchgear and low-voltage DC power circuit breakers, respectively.
• Industrial field: UL certified motors are widely used in industrial automation equipment, pumps, fans, compressors, etc., to ensure the safe operation of equipment.
• Medical equipment: UL certified motors are used in medical fans, infusion pumps, electric beds, etc. to ensure the safety and reliability of the equipment.
• Household appliances: such as vacuum cleaners, washing machines, kitchen appliances, etc., to ensure the safety and stability of household appliances.
• Automotive industry: UL certified motors are used in various types of electric systems in modern automobiles, such as engines, power transmission systems, air-conditioning systems, and so on.
