Underwriters Laboratories Inc. was founded in 1894 by William Henry Merrill. Early in his career as an electrical engineer in Boston, a 25-year-old Merrill was sent by underwriters issuing fire insurance to assess risk, and investigate the World Fair's Palace of Electricity. In order to determine and mitigate risk, Merrill found it necessary to conduct tests on building materials. Upon seeing a growing potential in his field, Merrill stayed in Chicago to found Underwriters Laboratories.
Merrill soon went to work developing standards, launching tests, designing equipment and uncovering hazards. Aside from his work at UL, Merrill served as the National Fire Protection Association's secretary-treasurer (1903–1909) and president (1910–1912) and was an active member of the Chicago Board and Union Committee. In 1916, Merrill became UL's first president.
UL published its first standard, "Tin Clad Fire Doors", in 1903. In 1905, UL established a Label Service for certain product categories that require more frequent inspections. In 1906, UL introduced the UL Mark to indicate products that had passed their testing. UL inspectors conducted the first factory inspections on labeled products at manufacturers' facilities.
UL has expanded into an organization with 64 laboratories, testing and certification facilities serving customers in 104 countries. It has evolved from its roots in electrical and fire safety to address broader safety issues, such as hazardous substances, water quality, food safety, performance testing, safety and compliance educationand environmental sustainability.
On January 1, 2012, Underwriters Laboratories transformed from a non-profit organization to a for-profit company in the U.S. A new subsidiary named simply UL LLC, a limited liability corporation, took over Underwriters Laboratories’ product testing and certification business.
Washing of surfaces and laundry is one of the promising areas were ultrafine bubbles can make a difference in the application. Reducing the amount of detergent, has a positive effect by reducing pollution, washing laundry without detergent, would greatly benefit the environment. Ultrafine bubbles can lower the surface tension of water, the large amounts of oxygen molecules in bubbles charge the water negative.
