UL Certification

Detail Information
Product Description

Certification introduction
UL is the abbreviation of Underwriter Laboratories Inc. UL Safety Testing Institute 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, non-profit, professional organization that conducts experiments for public safety. Different from FCC certification, UL certification is a safety certification. UL is mainly engaged in product safety certification and business safety certification business. Its ultimate goal is to obtain products with a considerable safety level for the market and contribute to ensuring the safety of personal health and property. . In the United States, UL is a symbol of safety signs for consumers. Globally, UL is one of the most trustworthy conformity assessment providers for manufacturers.

American UL
Certification Category
UL's product certification and testing services can be mainly divided into listing, recognition and classification.

1. Listed (LISTED):
Generally speaking, listing only applies to complete products and various devices and devices that are replaced or installed by qualified personnel on site. Various products belonging to UL listing services include: household appliances, medical equipment, computers, commercial equipment As well as various electrical products used in buildings, such as power distribution systems, fuses, wires, switches and other electrical components. Products listed by UL can usually be marked with the UL listing mark on each product. Usage of column name flags.

2. Recognized:
Recognition service is an item in UL services, and the products it identifies can only be used as components and raw materials in UL listed, classified or other recognized products. Approved products are not structurally complete, or have certain limitations in use to ensure expected safety performance. In most cases, tracking services for approved products fall into category R. 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 require an approval mark.

3. Classification:
Grading services only evaluate the specific hazards of products, or evaluate products that implement standards other than UL standards (including internationally recognized standards, such as IEC and ISO standards, etc.). Generally speaking, most graded products are not products for consumer use, but products for industrial or commercial use. The classification mark in the UL mark indicates that the product has certain restrictions and regulations when it is certified by UL. For example, chemicals such as solvents used in industry are evaluated only in the range of possible fires when they reach their 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 However, because UL only regards X-ray as a classified product, it only evaluates its mechanical properties, electrical properties and other non-radiation properties.

Applicable product range
Electronic, electrical, mechanical or electromechanical products

As long as any electrical, mechanical or electromechanical product bears the UL mark, it means that the product has met the minimum requirements of the universally recognized product safety standards of the United States and Canada. It has been tested and complies with relevant product safety standards, and it also represents the production factory. Agree to undergo strict regular inspections to ensure the consistency of product quality, which can be sold to the US and Canadian markets.

application process

When a component has obtained UL certification or recognition, please prove the specific model of the component and indicate its UL file number.

(5) Electrical performance: for electronic and electrical products. Provide electrical schematics (circuit diagrams) and electrical performance tables.

(6) Structural diagram: For most products, the structural diagram or exploded diagram of the product, ingredient list, etc. need to be provided.

(7) Product photos, instructions for use, safety, etc. or installation instructions, etc.


2. People make decisions based on the product information provided.
When the product information is complete, UL engineers will make the following decisions based on the information: the UL standard on which the experiment is based, the engineering cost of the test, the time of the test, the number of samples, etc., and will notify you in writing and provide a formal application form and tracking service. The agreement will be sent to your company. The fee limit is indicated in the application form, which is the maximum engineering fee estimated by UL based on the testing project. This fee limit cannot be exceeded without your company's written authorization.


3. Apply for company remittance and return application form and samples
The applicant for UL certification signs the application form and tracking service agreement, and sends the form back to UL. At the same time, the sample is sent by bank transfer at the post office or by express delivery. Please conduct appropriate inspections on the samples submitted for inspection. Description (such as name, model). Please send the application form and samples separately. For each application project, UL will assign a unique project number (Project No.). When remitting money, sending samples and application forms, indicate the project number and the name of the applying company to facilitate UL's inspection.


4. Product testing
After receiving the application form, remittance, and experimental samples signed by your company, UL will notify you of the completion time of the experimental plan. Product testing is generally conducted in UL laboratories in the United States, and UL can also accept audited third-party test data. Experimental samples will be returned or destroyed at your request. If the product test results meet the requirements of UL standards, UL will issue a test qualification report and follow-up service procedures (FollowUp Service Proccdure). The test report will detail the test situation, the indicators achieved by the sample, product structure and safety signs suitable for the use of the product. The tracking service details include a description of the product and instructions for UL regional inspectors. A copy of the test report is sent to the applicant company, and a copy of the tracking service details is sent to each production plant.


5. The applicant is authorized to use the UL mark
The UL regional inspector in China contacts the production factory for the Initial Production Inspection
.IPI), the inspector checks the status of your products and their parts on the production line and warehouse to confirm whether the product structure and parts are consistent with the tracking service details. If required in the details, the regional inspector will also conduct a witness test , when the inspection results meet the requirements, the applicant is authorized to use the UL mark.

UL necessity
Products sold in the U.S. market require mandatory UL certification. Whether they are products in the United States or products exported to other countries, they must undergo UL certification testing. We can see many electronic products in the market. All products have the UL certification mark, which is a conduction and radiation test of the product. It is of great significance in the US market. UL certification is an important passport and pass in the US market. Only products with this mark can enter smoothly. to the US market.
