UL Certification

UL is mainly engaged in product safety certification and safety management certificate business, with the ultimate aim is for the market by a considerable level of product safety for human health and property is guaranteed to contribute. Product safety certification as to eliminate technical barriers to international trade in terms of effective means, UL to promote the development of international trade also played an active role. UL Certification
UL was founded in 1894, mainly by the initial phase of UL fire insurance sector to provide capital to maintain movement, until 1916, UL was completely independent. After nearly a hundred years of development, UL has become a world-known certification body has its own set of strict system of organization and management, standards development and product certification procedures. UL by a security expert, government officials, consumers, education, utilities, insurance and standards department of the Council composed of representatives of management, daily by the president, vice president of treatment. Currently, UL has five laboratories in the United States, headquartered in Chicago, Northbrook north of the town, while Taiwan and Hong Kong were established in the corresponding laboratory. In the U.S., consumers, UL mark is a symbol of security, global, UL is the most trusted manufacturers to provide one of the conformity assessment.

Edit this paragraph services
UL product certification, testing the types of services can be divided into column names, recognition and classification.
1. Column names (LISTED):
In general, the listing only applies to complete products, and qualified personnel in the field to replace or install a variety of devices and equipment, UL listing services are a variety of products including: home appliances, medical equipment, computers, business equipment and the role of building all types of electrical products, such as power distribution system, fuses, wires, switches and other electrical components and so on. The UL listing of products, usually marked on each product's UL Listing Mark. Listing Mark of usage.
2. Recognized (Recognized):
UL approved service is a service project, the identification of the product only in the UL Listing, Classification or other approved products as components, raw materials used. Approved products in the structure is not complete, or have certain restrictions on use to ensure the desired security. In most cases, the tracking services are authorized products are R classes. L is recognized products like electronic line (AVLV2), processing wire (ZKLU2), wiring harness (ZPFW2), aluminum (DVVR2), and metal flexible tube (DXUZ2). Approved product requirements with the approval mark.
3. Classification (Classification):
Grading Services only to evaluate the specific hazards of products, or UL standards other than the implementation of standards (including the internationally recognized standards such as IEC and ISO standards, etc.) to evaluate the product. Most consumer grade products are not in general use products, but industrial or commercial use of the product. The Classification Mark UL mark indicates the product identified by the UL have a certain range of restrictions and regulations. For example, a solvent for industrial use such chemicals, to reach its ignition temperature is only possible to evaluate the range of fire. The classification of certain products and services, listing services, the same, but generally only one aspect of a product or a number of aspects of evaluation, such as in the United States, medical X-ray diagnostic apparatus such equipment to the country to comply with U.S. laws and radiated emissions and the provisions of the beam accuracy, but because only the X-ray as a UL rating products, they only evaluate its mechanical properties, electrical properties and other non-radiative properties of these aspects.
4. Multiple Listing, approval or multi-grade multi-service:
When an applicant in obtaining UL listing above, approval or grading service, and its products to another company's name to the production to meet the needs of sales, may apply for multiple listing, multiple authorized or multiple classification services In this case, get the column name, the manufacturer of approval or grading is allowed to use the product directory in the name of another company, but the products are the company code, product code or a UL company acceptable to the other features, column name must be the original, approved or consistent classification of products.
5. "AL" listing, approval or classification of service
: UL, if the applicant did not want to get your own column names in the name of the company, approval or classification of service, he can apply with another firm (usually a retailer or wholesaler) in the name of the column name, approval or classification, that is, " AL "listing, approval or grading service. With the multiple listing, multiple or multi-tiered services recognized the difference between the applicant is not out of their celebrity.
6. System Certification Services:
As a member of the International Accreditation Board, UL widely involved in ISO9000 quality system certification, ISO14000 environmental certification, QS9000 quality system certification and the automotive industry AS9000 quality system certification services to the aircraft industry. A total of 116 factories in the country to obtain UL certification system; of which 21 for the ISO9001 certification, ISO9002 certification for the 85, one for the ISO14001 certification, nine for the QS9000 certification.
7. UL's other services:

Overview
UL inspection inspector essentially mechanical operations. According to different product, based on the inspection inspectors have announced (Bulletin), Rule (Procedure), FUII (If yes, included in the Conditions), and UL standards (if there is demand FUII). If inspectors visit the factory, the factory is producing UL products, or UL product inventory, the inspector will sample one of the following ways: 1. Taken from various parts of the production line drawn from the warehouse with a full product . 2. Drawn from various parts of the warehouse with a complete product line. 3. Taken from the warehouse for a complete product split. The number of samples determined by the specific details, FUII (tracking test instructions), SAP (standard attached) or directly from the UL lab orders. Inspector Each inspection does not necessarily test all products, but they will try to at least a year or two years testing all the product categories or models. In general, UL requirements for factory production system is not too high, only requires measurement of the equipment once a year, Save the plant inspection records, and the unqualified products can have some means of control. Inspection, field representatives (UL inspectors) will focus primarily on the product itself, they will be based on one by one according to the inspection and check the product structure, components and assembly. For the components related to product safety, the general rules will specify the requirements of UL certified products, and will specify the manufacturer and model; for the shell, shields and other injection molded parts, under normal circumstances and conditions will specify the size of its raw material requirements. Site representative will verify the above and the rules set forth in the UL mark.
Field Test
In addition, if the rules or standards or FUII site requirements for product testing, field representatives will ask the factory inspector to do the appropriate tests, and field representatives in the next witness. If the rules are also required to send samples to UL for tracking test, the factory inspector should be made with the corresponding samples, sample labels written by the inspector, provide the address and sealed and then sent to the corresponding UL by the plant laboratory. If you plant the products in full compliance with the appropriate test standards UL, and no other violations of the local tracking service agreement, the inspector will issue a tracking survey report (Inspection Report); factory representative confirmed the accuracy of its contents after the report should be signature; a test is completed. If the test occurred during the test does not meet with the situation, the examiner will issue a change notice (Variation Notice), and to take appropriate measures according to specific circumstances.
UL mark removal
The UL mark is not authorized product, the inspector will be asked to remove the UL mark; for the product does not meet UL requirements, the factory inspector will remove the UL mark required or reworked to conform to requirements; If the plant does not agree to the above matters of opinion, you can retain the UL mark, but must stop the shipment, the inspector will notify the appropriate laboratory to decide whether to respond by the UL UL mark can be retained; if only some small problems do not affect the safety of the product nature, the examiner will accept the decision of an interim, and report to the appropriate laboratory; standard if it is some obvious errors, such as typing errors or unit error, does not affect the eligibility of the factory product, but as a document UL processing, inspectors will issue a notice of change. Under normal circumstances, unless it is UL's liability, the examiner will ask the factories that do not conform to explain to the appropriate laboratory, UL will be made according to your interpretation of the corresponding answer.
Final decision
Of course, the examiner's judgments only temporary, of course, the final decision in all laboratories in UL. If the factories do not agree with the practice of testing where the laboratory can reflect to the appropriate at this time, inspectors obligation to provide the name and contact methods. Notice confirming the change recorded in the content is correct, the factory representative shall sign the notice.
UL certified factory inspection
UL regional inspectors in China to contact the production plant for the first factory inspection (Initial Production Inspection, referred to as IPI), inspectors check your products, their parts and components in production lines and warehouses warehousing situation in order to confirm the product structure and components is consistent with the tracking service rules, if the details of the request, the regional inspector will conduct witnessed the experiment. When the test results meet the requirements, the applicant is authorized to use the UL mark. Following the IPI, the inspector may from time to time to factory inspection, inspection of product structure and to witness experiments. The frequency of inspections by the product type and production decisions, most types of products checked at least four times a year (the cost of tracking service costs are not included in the test.) Inspectors check to ensure that products continue to be consistent with the UL requirements, the product you plan to change the structure or components, please notice UL. Changes for small changes, do not repeat any experiment, UL can quickly change tracking service details, so that inspectors can accept such changes. When the UL product changes that affect their safety, the need to apply for the resubmission necessary testing samples.
Edit this paragraph certification review
UL certified products shipped in the first before the UL authorization to go through the provincial local province of China Import and Export Commodity Inspection Bureau (CCIB) sent to the factory inspection. Follow-up examination every year.
Edit this paragraph tracking test
Introduction
UL certification is an integral part of the column names in order to ensure the UL, UL approved products continue to meet the standards and requirements, UL developed a "test track" system. "Track Test" is sent by the distribution of UL's field representatives around the world to the local factory site to track the products on the UL test. Its purpose is to plant through the production process, inspection process and product control and tracking of UL standard test conditions for verification, to ensure that the manufacturer's production process, inspection process and the products always meet the UL requirements.
The basis for tracking test
Site representative to the factory, mainly based on "Tracking Test Conditions" for testing. "Tracking Test Rules" by UL engineering, inspection of the samples in the test preparation, this document includes a comprehensive description of the product, but also including photos, brochures and so on. It also provides manufacturing facility during production often have to do various tests, some test requirements for 100% of the product, such as the pressure test. Some tests can be carried out sampling at the same time, also provides on-site inspection at the factory site representative must be spot checks of pilot projects. Field trials on behalf of the basis of such detailed information and test results provided to determine eligibility.
Follow the classification of testing products
Review and the review is divided into the first quarterly review, first review of the relatively higher cost, UL's Follow-divided into the R class and L class. L type of service is mainly used for and safety-related products, such as fire extinguishers, smoke detectors, fire doors and a large number of output products, such as electrical equipment, wires and circuit breakers. Categories of products belonging to L, the production plant must be ordered directly to the UL label on the product. R type of service is mainly used in electrical equipment such as electric fans, televisions, hair dryers, ovens and other lines commonly used to produce the corresponding products.
Edit this paragraph charges
UL's Follow-cost consists of two parts, one is an annual service fee, and the second is to track the inspection fee. Its annual service fee of 580 dollars in January of each year, UL will be sent to the factory bill, which for the R class and L are the same products; if, track inspection rules to the United States requested to send samples for testing, the UL Testing fees will be charged to the factory. For the track inspection costs, R class and L have a very different products:
R Class Service
R type of service, and its track inspection fees and a direct correlation between the frequency of inspection. If inspectors visit the factory, the factory is producing or stock of UL products, the inspection fee is $ 280 each; the other hand, compared with $ 93.5; if the product rework and lead to increased frequency of inspection is the inspection was also at 93.5 dollars. Inspection costs and product complexity and inspectors in the plant not directly related to the time required. If you belong to a special test, the test under normal circumstances by the time spent in the factory and then test to determine the rate, the rate in the UL decided to implement the special inspection will inform the factory. Test the implementation of the bill will normally be sent within one month after.
L type of service
For the L type of service, UL is tracked through the tags to collect inspection fees. Apply to the purchase of the factory UL label, the price tag includes the cost of two aspects: the cost of labels and service fees (ie UL's Follow-costs). Therefore, UL-site inspection and factory representatives, UL no charge to the factory, unless a large number of products or UL retesting the plant implemented a special test. Either L or R class type of service, UL are required to plant as soon as possible after receipt of invoice sent, otherwise, when the time limit more than 3 months, UL will take clear your files. If you still do not understand costs, you can contact the local test center or contact the accounting department with the UL.
