Product safety certification for the elimination of technical barriers to international trade in terms of effective means, UL to promote the development of international trade also played an active role.
UL was founded in 1894, the initial phase of the main UL fire in the insurance sector by providing capital to maintain the action, until 1916, UL was completely self-sustaining. After nearly a century of development, UL has become a world-known certification body, has its own set of strict organization and management systems, standards development and product certification program. UL by a safety experts, government officials, consumers, education, utilities, insurance and standards department of the Council composed of representatives of management, daily work by the president, vice president of processing. Currently, UL has five laboratories in the United States, headquartered in Northbrook town north of Chicago, while Taiwan and Hong Kong were established in the corresponding laboratory in the United States, UL is safe for consumers sign symbol. The world, UL is the most trusted manufacturers of conformity assessment providers.

UL certified product type
UL product certification, testing the types of services can be divided into column names, recognition and classification.
1) The column names (LISTED): Generally speaking, applies only to a complete listing of products and qualified personnel in the field to replace or install a variety of devices and equipment, are UL listed services a variety of products including: home appliances , medical equipment, computers, business equipment, and role in building various types of electrical products, such as distribution systems, fuses, wires, switches and other electrical components and so on. The UL listed product, usually marked on each product in the UL Listing Mark. Listing Mark of usage.
2) recognized (Recognized): UL approved service is a service project, the identification of the products only in the UL Listing, Classification or other approved products as components, raw materials use. Approved products in the structure is not complete, or have certain restrictions on use to ensure the desired safety performance. In most cases, approval of products tracking services in R class. L class products are recognized electronic line (AVLV2), processing wire (ZKLU2), 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 to perform other than the standard UL standards (including the internationally recognized standards such as IEC and ISO standards, etc.) of product evaluation. Generally speaking, most consumer grade products are not 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, on the use of industrial chemicals such as solvents, to reach its ignition temperature is only possible to evaluate the range of fire. The classification of certain products and services serve the same column names, but generally only one aspect of the product or to evaluate certain aspects, such as in the United States, this type of medical X-ray diagnostic equipment to the country to comply with U.S. laws and radiation emission and beam accuracy requirements, but only because the UL classification of products as the X-ray, only the evaluation of its mechanical properties, electrical properties and other non-radiative properties of these aspects.
4) multiple listing, multiple or multi-tiered services recognition: When the applicant to obtain a 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 column names, or multiple multi-recognized rating service, in which case, get the column name, approval or classification of manufacturers are allowed to use the product list in the name of another company, but the products are company code , product code or UL's acceptable to other characteristics, must be the original column names, product approval or production levels consistent.
5) "AL" column name recognition or classification of service: If UL applicants do not want to get out in the name of their company name, recognition or classification of service, he can apply with another firm (usually a retailer or wholesaler) in the name of the column name, recognition or classification, that is, "AL" column name, 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.

UL Listing Mark

This is one of the most common UL Marks. If the product is labeled with the mark, it means that the product samples meet UL's safety requirements. These requirements are mainly UL's own published safety standards. This type of tag is typically seen in the following categories of products: appliances, computer equipment, stoves and heaters, fuses, power panels, smoke and carbon monoxide detectors, fire extinguishers and sprinkler systems, personal flotation devices, such as life jackets and life buoy, bulletproof glass and thousands of other products.
◇ C-UL Listing Mark

This mark applies to products sold on the Canadian market. In accordance with Canadian safety requirements for such a tag affixed to the product evaluation. Canadian and U.S. safety requirements, safety requirements may be different. The following types of devices can see this on the mark: electrical and computer equipment, vending machines, household burglar alarm systems, lighting, and many other types of products.
◇ C-UL US Listing Mark
UL in early 1998 to introduce this new Listing Mark. It said that both comply with U.S. requirements, but also with Canada's claim. Canada / United States flag is optional. UL encourages those products both in the United States evidence, and evidence of the manufacturers in Canada to use this new combination of tags, but manufacturers can continue using only the United States or Canada for the UL mark.

◇ Classification Mark

The UL mark appears after the assessment of products. UL has affixed the mark on the special properties of certain products were evaluated. Here is the application of some special properties in a limited range of risk, or limited or special conditions of use. A typical situation is that UL Classified product is a versatile building materials and industrial equipment. For example, the device type from the UL rating are diving suits, fire doors, fire protection and industrial trucks.
◇ C-UL Classification Mark

The Classification Mark applies to products sold on the Canadian market. It indicates that UL has Canadian standards, on certain conditions or characteristics of hazardous products were evaluated. For example, C-UL grade products including air filters, fire stop devices, certain types of roofing systems.
◇ C-UL US Classification Mark

UL in early 1998 marked the introduction of this new classification. It said that both comply with U.S. requirements, but also with Canada's claim. Canada / United States flag is optional. UL encourages those products both in the United States evidence, and evidence of the manufacturers in Canada to use this new combination of tags, but manufacturers can continue using only the United States or Canada for the UL mark.
◇ approved parts and Canadian recognition component marks marks

Ordinary consumers rarely see these tags, because they are used in parts, these parts are some of the larger product or system components. These components themselves can not directly constitute a complete product, or its use restricted. Can be seen in large parts of the product approval marks, including some switches, power supplies, printed wiring boards, some kinds of industrial control equipment, and thousands of other products. Canada intends to sell the products on the market Recognized Component mark affixed with a "C" letter.
◇ approval for parts of Canada and the U.S. mark

This is a new UL Recognized Component Mark, it was April 1, 1998 to take effect. It can be used both by UL in accordance with Canadian requirements and demands evidence in accordance with U.S. components. Originally did not intend to introduce a combination of UL Recognized Component mark, but because both of those products sold in Canada, and sold in the United States, the UL certification customers like Canada / United States lists and classification tag, so the introduction of this new marker.
◇ System Registration mark

The UL mark registered company in the product can not be seen. It is said that the meaning is: the adoption of a facility management system in accordance with UL standards assessment. By UL to assess their management systems to process, can be used to enhance the corporate image, becoming an integral part of marketing strategy. UL standards for use in this regard is: ISO9000 series quality assurance standards; QS-9000 and TE complementary standards, which are the three U.S. auto manufacturers to their suppliers to develop quality standards; ISO14001, the environmental management system covering standards; AS9000, aerospace quality management system; TL9000, telecommunications quality management system; social responsibility management system SA8000.
◇ Marine Mark

UL Marine mark appears on the marine use of those products. This mark is affixed to the product have been published in accordance with UL standards and other marine safety standards and norms applicable to the assessment. When the product is exposed to some of the harsh maritime environment, such as vibration, shock, fire protection, water intrusion and corrosion caused by salt water, the boat or yacht will be damage. UL published the above-mentioned marine safety standards and other applicable standards and specifications that address these damages. Marine UL mark for the type of device, including alternators, batteries / charger / power change control, navigation lights, fuel tank, filter and pump.

2 product testing
Product testing is generally the UL laboratories in the United States, UL is also acceptable audited in third-party test data. Experimental samples will also send your request or be destroyed. If the product test results meet the requirements of UL standard, UL tested and the company will issue a report and tracking service rules (FollowUp Service Proccdure) test report will detail the test conditions, the sample reached the target, the product structure and appropriate use of the product safety signs. Details of the tracking service includes the product description and instructions for inspectors UL region. A copy of the inspection report sent to the applicant company, a copy of the tracking service rules sent to each production plant.
3, the applicant is authorized to use the UL mark
UL inspectors in China, contact the regional production plant for the first factory inspection (Initial Production Inspection. IPI), inspectors check your products, parts and components in production lines and warehouses warehousing situation in order to verify whether the product structure and parts rules consistent with the tracking service, if the details required in the regional inspectors 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 will check from time to time to the factory to check the product structure and to witness experiments, the frequency of inspections by the type of product and production decisions, most types of products be inspected at least four times a year, inspectors check to to ensure that products continue to be consistent with the UL requirements, the product you plan to change the structure or components before you notice UL, changes for small changes, do not repeat any experiment, UL can quickly change tracking service rules, so that inspectors can accept such a modification. When the UL product changes that affect their safety, the need for applicants to submit samples of the necessary re-testing.
Tracking service is not included in the test costs.
If the product test results can not meet UL standard, UL will notify the applicant, indicating the existence of the problem, the applicant to improve product design, you can re-produce for examination the product, you should tell the UL engineer products that do what improvements over its decision to UL certification is to apply the steps.

UL certification test details
UL inspector's test is essentially a mechanical operation. Depending on the product, the inspector's test based on a bulletin (Bulletin), Rule (Procedure), FUII (if included in the Conditions) and UL standards (if FUII in demand).
If inspectors visit the factory, the factory is producing the UL, the UL product or 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 complete product.
(2) to extract various components from the warehouse with a complete product line.
3 taken from the warehouse for a full product split.
The specific number depends on the sampling rules, FUII (tracking test instructions), SAP (standard attached page) or directly from the UL lab orders. Inspector Each inspection does not necessarily test all products, but they will try at least a year or two years test 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 their own factory inspection records, and substandard products have some means of control can be.
Inspection, on-site representatives (UL inspectors) will focus primarily on the product itself, they will check the products one by one based on the test structure, components and assembly. For the components related to product safety, general rules will specify requirements for UL certified products, and will specify the manufacturer and model; for the shell, shields and other plastic parts, general rules will specify their requirements of raw materials and dimensions. Site representative will verify the details of the above and set forth in the UL mark.
In addition, if the rules or standards or FUII required field test the product, on-site 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, factory inspectors should be made with the corresponding samples, sample labels written by the inspector, provide address and sealed and then sent to the corresponding UL by the plant laboratory.
If the plant produces the corresponding products in full compliance with UL test requirements, and no other violation tracking service agreement where the inspector will issue a tracking survey report (Inspection Report); factory representatives to confirm the accuracy of its contents on the report after signature; a test is completed. If the test occurred during the test does not meet with the situation, inspectors will issue a notice of change (Variation Notice), and take appropriate measures according to specific circumstances.
Products used for unauthorized UL mark, the examiner will be asked to remove the UL mark; the product does not meet UL requirements, the inspector will be required to remove the UL mark or rework the factory 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 shipments, the inspector will notify the appropriate laboratory, responded by UL to decide whether to retain the UL mark; if only some small problems do not affect the safety of the product nature, the inspector will make a temporary decision to accept and report to the appropriate laboratory; standard if it is some obvious errors, such as typing errors or bit errors, the product does not affect the plant's eligibility, but the document as a UL process, the inspector will issue a notice of change. Under normal circumstances, unless it is UL's responsibility, the inspector will ask the factory does not meet the laboratory to the corresponding explanation, UL will be made according to your interpretation of the corresponding answer.
Of course, the inspector is only temporary judge, the final decision of course, the various laboratories in the UL. If the factories do not agree with the practice test where can reflect to the appropriate laboratory, at this time, inspectors obligation to provide the appropriate contact and contact methods. Changes recorded in the confirmation notice the content is correct, the factory representative shall sign the notice.

UL certified factory inspection
UL inspectors in China, contact the regional production plant for the first factory inspection (Initial Production Inspection, referred to as IPI), inspectors check your products, parts and components in production lines and warehouses warehousing situation in order to confirm the product structure and parts is consistent with the tracking service rules, if the details required in the regional inspectors witnessed the experiment will be conducted. When the test results meet the requirements, the applicant is authorized to use the UL mark.
Following the IPI, the inspector will check from time to time to the factory to check the product structure and to witness experiments. The frequency of inspections by the type of product and production decisions, most types of products checked at least four times a year (the cost of follow-up service costs are not included in the test). Inspectors check to ensure that products continue to be consistent with the UL requirements, you plan to change the product mix or parts, please notify UL. Changes for small changes, do not repeat any experiment, UL can quickly change tracking service rules, so that inspectors can accept this change. When the UL product changes that affect their safety, the need for applicants to submit samples of the necessary re-testing.

UL Certifications Follow
For the UL certification is an integral part, in order to ensure the UL Listed, UL approved products continue to meet the standards and requirements, UL developed a "test track" system. "Follow-Up" is distributed by the UL around the world to send representatives to the local site plant site to track the products of the UL test. Its purpose is through the factory production process, testing process and product control and tracking of UL's standards for inspection and verification rules to ensure that the manufacturer's production process, inspection process and the products always meet the UL requirements.
Follow-based
Representatives to the factory site mainly based on "Follow-rules" for testing. "Follow-Up Rules" by UL engineering department, in the submission of samples for test preparation, this document includes a comprehensive description of the product, including pictures] manual. It also provides manufacturing facility during production often have to do various tests, some test requirements for 100% of the product, such as pressure test. Some tests can be carried out sampling, also provides on-site inspection on behalf of the factory floor to sample the pilot project. Field Representative in accordance with the details of such tests and provides test results to determine eligibility.
Tracking test product categories
UL's Follow-Up class is divided into R and L classes. L type of service used 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 for electrical equipment such as electric fans, televisions, hair dryers, ovens and other commonly used to produce the corresponding line of products.
