UL Listed Safety Certifications

UL Listed Safety Certifications


UL is the abbreviation of the English Underwriter Laboratories (Underwriter Laboratories Inc.). The UL Safety Laboratory is the most authoritative in the United States and the largest private institution engaged in safety testing and identification in the world. It is an independent, not-for-profit, 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 and harmful to life and property; determine, write, and issue corresponding standards and help reduce and prevent life and property. Lost data, while conducting fact-finding business. In short, it is mainly engaged in product safety certification and operating safety certification business, and its ultimate goal is to obtain products with a relatively safe level for the market, and to contribute to the assurance of personal health and property safety. In terms of product safety certification as an effective means to eliminate technical barriers to international trade, UL also plays an active role in promoting the development of international trade.

UL was founded in 1894. In the initial stage, UL mainly relied on the funds provided by the fire insurance department to maintain its operations. It was not until 1916 that UL was completely independent. After nearly a hundred years of development, UL has become a world-renowned certification body, with its own set of strict organizational management system, standard development and product certification procedures. UL is governed by a council of representatives from safety experts, government officials, consumers, education, utilities, insurance, and standards departments, with day-to-day operations handled by the president and vice president. At present, UL has five laboratories in the United States, headquartered in Northbrook Town, north of Chicago, and has established corresponding laboratories in Taiwan and Hong Kong.

UL's product certification types can be divided into:

  • LISTED:

    Generally speaking, listing is only applicable to complete products and qualified personnel in other electrical components, etc. Products listed by UL can usually be marked with the UL listing mark on each product. Usage of column name flags.

  • Recognized:

    Recognized service is a project in UL service, and the products recognized by it can only be used as components and raw materials on UL listed, graded or other recognized products. Approved products are not structurally complete, or have certain limitations in use to ensure the expected safety performance. Tracking services for approved products fall under the R category in most cases. Approved products belonging to category L are electronic wire (AVLV2), processing wire (ZKLU2), wire harness (ZPFW2), aluminum wire (DVVR2), and metal flexible tube (DXUZ2). Approved products are required to carry the approval mark.

  • Classification:

    The classification service only evaluates the specific hazards of products, or evaluates products that implement other standards than UL standards (including internationally recognized standards, such as IEC and ISO standards, etc.). In general most graded products are not for consumer use, but for industrial or commercial use. The grading mark in the UL mark indicates that the product has certain restrictions and regulations when it is identified by UL. For example, chemicals such as industrial solvents are evaluated only in the range where fire may occur when the temperature reaches the ignition temperature. The grading service and listing service of some products are the same, but generally only one or several aspects of the product are evaluated. For example, in the United States, equipment such as medical X-ray diagnostic equipment must abide by US laws and regulations related to radiation emissions and However, because UL only regards X-ray as a graded product, it only evaluates its mechanical properties, electrical properties and other non-radiative properties.

  • Multiple listing, multiple accreditation or multiple grading services:

    When a UL applicant obtains the above-mentioned listing, accreditation or grading services, and its products are produced in the name of another company to meet the needs of sales, it can apply for Multiple Listing, Multiple Approval or Multiple Rating Services, in which case the manufacturer listed, approved or graded is permitted to use the name of another company in the product list, but the product is subject to a company code, product code or Except for other characteristics that UL considers acceptable, it must be consistent with the original listed, approved or graded product.

  • "AL" listing, accreditation or grading services:

    If the UL applicant does not want to obtain listing, accreditation or grading services in the name of his own company, he can apply for the name of another firm (usually a retailer or wholesaler) Application for listing, accreditation or grading is called "AL" listing, accreditation or grading service. It differs from multiple listing, multiple recognition or multiple classification services in that the applicant is not a listed person.

  • System certification services:

    As one of the members of the International Accreditation Committee, UL is widely involved in ISO9000 quality system certification, ISO14000 environmental protection certification, QS9000 automotive industry quality system certification and AS9000 aircraft industry quality system certification services. So far, a total of 116 factories in China have obtained UL system certification; 21 of them are ISO9001 certified, 85 are ISO9002 certified, 1 is ISO14001 certified, and 9 are QS9000 certified.

  • UL's other services:

    such as certification services, inspection services, factual judgment services, research services, etc.
