UL is an insurance laboratory and a for-profit organization, which means that it must be responsible for UL-certified products. Because we are responsible for the product, we have strict implementation standard control from parts to finished products. We must pass the product testing standards set by UL. We must sign many agreements with applicants and manufacturers of power cord manufacturers to ensure that they are regulated in law. Follow UL regulations; because you are responsible for the product, you must conduct multiple factory inspections to ensure that the actual production meets the requirements.
UL has worked hard to control from beginning to end to ensure that the products sold in the United States meet the requirements. Because he also has to control the risk, or he has to pay the price. UL is not responsible for the samples, but for the final products, so the application will be more cumbersome and rigorous, and the price will not be low.
UL is short for baiUnderwriter Laboratories Inc. (baiUnderwriter Laboratories Inc.). It is the most authoritative in the United States and the largest private organization engaged in safety testing and identification in the world. It is an independent, profit-making professional organization that conducts experiments for public safety. It uses scientific testing methods to study and determine whether various materials, devices, products, equipment, buildings, etc. are harmful to life and property and the degree of harm; to determine, compile and issue corresponding standards and help reduce and prevent life Data on property losses, while carrying out fact-finding research business. UL certification is a non-compulsory certification in the United States, mainly for product safety performance testing and certification, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of the product.
UL was founded in 1894. In the initial stage, UL mainly relied on the fire protection insurance department to provide funds to maintain its operations. It was not until 1916 that UL was completely independent. As a member of the International Accreditation Committee, UL has extensively involved in ISO9000 quality system certification, ISO14000 environmental protection certification, QS9000 automotive industry quality system certification and AS9000 aircraft industry quality system certification services. There is no way to know when it was established. But the authority of UL is obvious to all.
