Introduction

Introduction to the logo

UL is principally engaged in product safety certification and business safety certification business, the ultimate goal is to get the market with a very safe level of goods for personal health and property security to ensure that to contribute. In terms of product safety certification as an effective means of eliminating technical barriers to international trade, UL also plays an active role in promoting the development of international trade.

UL was founded in 1894, the initial stage of the UL mainly by the fire insurance sector to provide funds to maintain the action, until 1916, UL was completely independent. After nearly a hundred years of development, UL has become a world-renowned certification body, its own with a set of strict organizational management system, the standard development and product certification procedures. UL is governed by a board of directors of security experts, government officials, consumers, education, public utilities, insurance and standards departments. The day-to-day work is handled by the president and vice president. At present, UL in the United States has five laboratories, headquartered in North Chicago, Northbrook town, while in Taiwan and Hong Kong, respectively, set up a corresponding laboratory. In the United States, for consumers, UL is a symbol of security signs, the world, UL is the manufacturer's most trusted one of the qualified assessment provider.

Logo style

The UL mark is usually identified on the product and / or product package to indicate that the product has been UL approved and meets the safety requirements.

composition

The most important part of these marks is the UL symbol, which is a registered trademark of UL, as shown in Figure 2.

UL product certification, the types of test services can be divided into column name, recognition and classification.

1. column name (LISTED):

In general, the column name is only applicable to the complete product and qualified personnel in the field to replace or install a variety of devices and devices, UL listed services include a variety of products include: household appliances, medical equipment, computers, commercial equipment As well as the role of various types of electrical products in buildings, such as power distribution systems, fuses, wires, switches and other electrical components. UL listed products, usually in each product marked on the UL listed mark. The use of the column name.

2. Recognized:

Recognized service is a UL service in a project, its identification of products only in the UL listed, grading or other recognized products as components, raw materials used. The approved product is not structurally complete, or has a certain limit in its use to ensure that the intended safety performance is achieved. In most cases, the tracking service of the approved product belongs to the category R. Class A approved products are electronic wire (AVLV2), processing wire (ZKLU2), wiring harness (ZPFW2), aluminum (DVVR2), and metal flexible tube (DXUZ2). Approved product requirements with a recognized mark.

3. Classification:

The grading service evaluates only the specific hazards of the product or evaluates the products other than the implementation of the UL standard (including internationally recognized standards such as IEC and ISO standards). In general, most graded products are not products that consumers use, but products that are used industrially or commercially. The classification mark in the UL mark indicates that the product has a certain limit and a specified range when UL is identified. For example, a chemical such as a solvent for industrial use is evaluated only for the range of fire that may occur when it reaches the ignition temperature. Some products are graded in the same service as a listed name, but generally only one or several aspects of the product are evaluated. As in the United States, medical devices such as the United States, medical X-ray diagnostic apparatus to comply with US law and the relevant radiation and beam Flow accuracy, but because UL only X-ray as a grading product, so only to evaluate its mechanical properties, electrical performance and other non-radiative performance of these aspects.

4. Multiple column name, multiple recognition or multiple grading services:

When a UL applicant obtains the above listed, recognized or graded service, its product is to be produced in the name of another company to meet the sales needs, you can apply for multiple column name, multiple recognition or multiple grading services, in this In the case of a manufacturer whose name, approval or classification is permitted, it is permitted to use the name of another company in the product list, but the product must, in addition to the company's code, product code or other features that UL considers acceptable, Listed, approved or graded products.

5. "AL" column name, recognition or classification services:

If the UL applicant does not wish to use the name of the company to obtain the name, recognition or classification service, he may apply for another firm (usually a retailer or wholesaler) in the name of the application name, recognition or classification, that is, "AL" Name, approval or classification service. The difference between multiple quotations, multiple recognition or multiple grading services is that the applicant is not a celebrity.

6. System certification services:

As one of the members of the International Accreditation Board, 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. In the domestic a total of 116 factories to obtain UL system certification; of which 21 for the ISO9001 certification, 85 for the ISO9002 certification, one for the ISO14001 certification, 9 for the QS9000 certification.

7. Other UL services:

Such as proof of service, inspection services, judgments of the service, research services.

Tracking test

Introduction

As an integral part of UL certification, UL has developed a "tracking test" system in order to ensure that the UL listed, approved products continue to meet UL standards and requirements. "Tracking test" is sent by the UL distributed throughout the world on behalf of the scene to the local factory production site on the UL product tracking test. The purpose is to ensure that the manufacturer's production process, inspection process and product are always in accordance with UL's requirements by verifying the production process, inspection process and product of the plant, the UL standard and the tracking inspection rules.

Follow the test

On-site representatives to the factory after the main "follow-up inspection rules" for testing. The "Follow-up Inspection Rules" was prepared by UL Engineering, after testing the samples submitted, including a comprehensive description of the product, including photographs, brochures and so on. It also specifies the various tests that are frequently done during the production of the plant, some of which require 100% of the product, such as a withstand voltage test. Some tests can be carried out at the same time, but also provides on-site representatives in the factory site inspection must be checked when the pilot project. The on-site representative is judged on the basis of the detailed information and regulations of such tests.

Tracking the classification of inspection products

Review is divided into the first review and quarterly review, the cost of the first review is relatively high, UL tracking test is divided into R class and L class. L class services are mainly used for life safety related products, such as fire extinguishers, smoke detectors, fire doors and some considerable production of products, such as electrical equipment, wires and circuit breakers. For products belonging to category L, the manufacturer must be affixed directly to the product on the UL order label. Class R services are mainly used for electrical equipment, such as fans, televisions, hair dryers, ovens and other commonly used products to produce the corresponding line.

Charges

UL tracking test costs by the two major components, one is the annual service fee, the second is tracking the cost of inspection. The annual service fee of $ 580, in January each year, UL will send the bill to the factory, which for the R class and L products are the same; if the tracking test requirements to send samples to the United States for testing, the UL But also to the factory charge test fees.

For tracking and testing costs, R and L products are very different:

Class R services

R class service, the tracking test fee and the number of tests have a direct relationship. If the inspector is in the factory, the factory is producing or stocking UL products, the cost of each inspection is $ 280; otherwise, it is $ 93.5; if the number of inspections is increased due to product rework, Dollar calculation. The cost of inspection and the complexity of the product is not directly related to the time required by the inspector at the factory. If it is a special inspection, it is generally determined by the time spent at the factory and the rate at which it was tested, which is notified to the factory when the UL decides to carry out the special inspection. Billing is usually sent within one month of inspection.

L class service

For Class L services, UL is charged through the label to track the cost of inspection. When the factory applies for a label to the UL application, the price of the label includes two costs: the cost of the label and the service charge (ie, UL's tracking test fee). Therefore, UL on-site representatives in the inspection factory, UL no longer charge to the factory, unless a large number of product re-inspection or UL on the implementation of a special inspection plant.

Regardless of Class R or Class L services, UL requires the factory to send the bill as soon as possible after the receipt, otherwise, when the time limit of more than 3 months, UL will clear your file. If you do not understand the cost of the place, you can contact the local test center or contact with the UL accounting department.
