UL Approved Equipment

What is UL?

UL was established in 1894 by William Henry Merrill for the testing of products' safety against fire and other dangers related to electricity for the purposes of U.S. insurance companies. The institute has since been testing materials, apparatuses, products, equipment, buildings, systems, etc., concerning the danger to life and property under the auspices of American Insurance Association. It is not directly related with the association but is a completely independent non-profit-making organization, which is known as the world-oldest and greatest authority for safety testing.

To ensure the safety of life and property against fire, electric shock or other dangers which may arise in using equipment, UL assumes the following missions from the consumers' point of view:

(1)	To establish safety standards
(2)	To test products based on those established standards
(3)	To make the test results known to insurers, government agencies, related organizations and general consumers

UL executes tests for above purposes, approves the products which clear applicable standards, and makes them known to the public. There are two methods for indicating UL approval:

(1) Listing service
This is generally referred to as "listing" and is applied to the products and parts which are manufactured so as to ensure safety under any working conditions. Considering that they are used by general consumers, comprehensive investigation and testing are made as to their safety. When accepted, they are given the "listing mark" and made known to the public by means of the categorized products list (Green Book) which is published by UL.

(2) Recognition service
This is applied mainly to the materials or parts which are assembled in final products in manufacturers' factories. When accepted, they are included in the registered parts list (Yellow Book).
