Project Description

Introduction to UL Certification

Underwriters Laboratories Inc (UL:) is an independent product safety certification body established in 1894 with a head office in Illinois, USA. UL’s main business is product safety, as well as standards and testing procedures for many products, materials, parts, tools and equipment.

UL Taiwan, established in 1988, is the first authorized laboratory set up overseas by UL’s US headquarters. In response to the growth of UL’s global organization, UL Taiwan officially merged with UL International Services BV (ULISBV), a new business established by UL in the Netherlands, on January 1, 2007. ULISBV is fully authorized by UL to perform all related work including UL certification, management system registration, etc. on behalf of UL. At present, UL Taiwan’s service base is located in Beitou, Taipei. It has advanced and complete testing and testing equipment and laboratories in the Asia-Pacific region, providing more immediate and localized testing services in the Asian and Taiwan markets.

UL certification service project

UL’s product certification and testing services are mainly classified into listing, recognition and grading.

  1. LISTED: Generally speaking, the listing name is only applicable to the complete product and various devices and devices that are qualified or replaced by the qualified personnel. The various products belonging to the UL listing service include: household appliances, medical equipment, Computers, commercial equipment, and various electrical products that function in buildings, such as power distribution systems, fuses, wires, switches, and other electrical components. UL listed products can usually be marked with a UL listing mark on each product. The use of the listing symbol.
  2. Recognized: An accredited service is a project in a UL service that identifies products that can only be used as components and raw materials on UL listings, grading, or other approved products. The approved product is not structurally complete or has certain limitations in its use to ensure the expected safety performance. In most cases, the tracking service for approved products falls into the R category. Approved products belonging to Class L are electronic wire (AVLV2), machined wire (ZKLU2), wire harness (ZPFW2), aluminum wire (DVVR2), and metal flexible pipe (DXUZ2). Approved product requirements are marked with an approval.
  3. Classification: The grading service evaluates only the specific hazards of the product, or evaluates products that implement standards other than the UL standard, including internationally recognized standards such as IEC and ISO standards. In general, most graded products are not products used by consumers, but products used industrially or commercially. The grading mark in the UL Mark indicates that the product has certain restrictions and specified ranges when it is UL-approved. For example, a chemical such as a solvent used in the industry only evaluates the range of fires that may occur when the ignition temperature is reached. Some products have the same rating service and listing service, but generally only evaluate one aspect or several aspects of the product. For example, in the United States, medical X-ray diagnostic equipment must comply with US laws and related radiation emissions. The specification of beam accuracy, but because UL only uses X-ray as a graded product, only its mechanical properties, electrical properties and other non-radiative properties are evaluated.
  4. Multiple listing, multiple recognition or multiple grading services: When a UL applicant obtains the above listed, approved or tiered services, its products are produced in the name of another company to meet the needs of the sale, you can apply for multiple columns. Name, multiple recognition or multiple grading services, in which case the manufacturer that is listed, approved or graded is allowed to use the name of another company in the product list, except for the company code, product code or UL company In addition to other features that are considered acceptable, they must be consistent with the original listed, approved or graded products.
  5. “AL” listing, accreditation or grading service: If a UL applicant does not want to obtain listing, accreditation or grading services in the name of his company, he can apply for another company name (usually a retailer or wholesaler) Name, recognition or grading, called “AL” listing, recognition or grading services. It differs from multiple listings, multiple recognitions, or multiple rating services in that the applicant is not a listed person.
  6. System Certification Service: As a member 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 certification, 85 are ISO9002 certification, 1 is ISO14001 certification, and 9 are QS9000 certification.
  7. Other UL services: such as certification services, inspection services, fact-finding services, research services, etc.
