Introduction to UL Certification

UL is an independent, non-profit professional organization that conducts tests for public safety. UL was founded in 1894 and initially relied on funding from the fire insurance department to maintain operations. It was not until 1916 that UL became fully independent. After nearly a century of development, UL has become a world-renowned certification body with a complete set of rigorous organizational management system, standard development, and product certification procedures. UL is managed by a board of directors composed of representatives from safety experts, government officials, consumers, education, utilities, insurance, and standards departments, with daily work handled by the President and Vice President. At present, UL has five laboratories in the United States, headquartered in Northbrook Town, north of Chicago, and has set up corresponding laboratories in Taiwan, China and Hong Kong respectively. UL stands for Underwriter Laboratories Inc. in English. The UL Safety Testing Institute is an authoritative institution in the United States and a relatively large private organization engaged in safety testing and certification in the industry. It is an independent, non-profit professional organization that conducts experiments for public safety. It adopts scientific testing methods to study and determine whether various materials, devices, products, equipment, buildings, etc. are harmful to life and property, and the degree of harm; Determine, write, and distribute corresponding standards and materials that help reduce and prevent damage to life and property, while conducting fact finding research. In short, it mainly engages in product safety certification and business safety certification, with the aim of providing the market with products with a considerable level of safety and contributing to ensuring personal health and property safety. In terms of product safety certification as an effective means of eliminating technical barriers to international trade, UL also plays a positive role in promoting the development of international trade.

UL certification process

We are UL Witness Free Laboratory, which means that UL engineers do not need to come to our laboratory to observe the testing. Our laboratory will issue a report within two weeks, submit it to UL, and then arrange for factory inspection. If it passes, evidence can be obtained. This cycle takes about a month from the time you submit the complete information.
If there is anything else you need to know, please see my personal information and contact me.

UL Certification - Certification Process
The UL certification process for product application for the UL mark includes five steps:
1. The applicant submits relevant company and product information
Written application: You should request UL to conduct testing on your company's products in writing.
Company Information: Provide detailed and accurate names, addresses, contact persons, postal codes, telephone numbers, and faxes of the following units in both Chinese and English.
(1) Application company: A company that submits a product testing application and is responsible for all engineering service fees
(2) Listed companies: Companies whose names are listed in various product catalogs published by UL Corporation
(3) Production factory: the manufacturer and producer of products.
Product information: Product information should be provided in English. Firstly, to determine whether your product falls within the scope of UL testing, you can consult with UL Teng'an Cap Laboratory.
(1) Product Name: Provide the full name of the product.
(2) Product model: List in detail all product models, varieties, or classification numbers that require experimentation.
(3) The intended use of the product: for example: home, office, factory, coal mine, ship, etc.
(4) Parts List: Detailed listing of the components and models (classification numbers) that make up the product, rated values, and manufacturer names. For insulation materials, please provide the name of the raw material, such as: GE Polycarbonate,lexan Type    104。 When the 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 meters.
(6) Structure diagram: For most products, it is necessary to provide the product's structure diagram or explosion diagram, ingredient list, etc.
(7) Product photos, instructions for use, safety measures, installation instructions, etc.
2. People make decisions based on the provided product information
When the product information is complete, UL engineers will make the following decisions based on the information: UL standards to be used for the experiment, engineering costs for testing, testing time, sample quantity, etc. They will notify you in writing and send the formal application form and tracking service agreement to your company. The application form specifies the cost limit, which is an estimated engineering cost by UL based on the testing project. Without written authorization from your company, this cost limit cannot be exceeded.
3. Apply for company remittance, return application form and samples
The applicant for UL certification shall sign the application form and tracking service agreement, and send the form back to UL company. At the same time, samples shall be sent by bank transfer to the post office or express delivery. Please verify the samples sent for inspection
Provide appropriate explanations for the product (such as name, model). Please send the application form and samples separately. For each application project, UL will assign a project number (Project Number)
When remitting, sending samples, and applying for forms, please indicate the project number and the name of the applying company for UL to check.
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 third-party testing data that has been audited. The experimental samples will be returned or destroyed according to your request.
If the product testing results meet UL standard requirements, UL company will issue a qualified testing report and Follow Up Service details
The Procpure testing report will detail the testing results, the indicators achieved by the sample, the product structure, and the safety signs suitable for the use of the product. The tracking service details include product descriptions and UL regions
Guidance instructions for inspectors. A copy of the testing report will be sent to the applying company, and a copy of the tracking service details will be sent to each production factory.
5. The applicant is authorized to use the UL logo
The UL regional inspector in China contacts the production factory for the initial production inspection
. API), the inspector checks the condition of your product and its components in the production line and warehouse storage to confirm whether the product structure and components are consistent with the tracking service details. If required by the details, the regional inspector will also conduct inspections
Conduct witness experiments, and when the inspection results meet the requirements, the applicant is authorized to use the UL mark.

 

UL certification mark

The use of UL's listing, grading, and approval marks on or in connection with products is a method designated by UL to distinguish products produced under UL's tracking inspection services. The appearance of a company's name on UL's product catalog does not necessarily mean that all of its products are listed, graded, or recognized by UL. Only products bearing the UL mark can be considered as products produced under UL's tracking inspection services.
For different types of services provided by UL, the UL mark can be divided into three categories: listing, grading, and accreditation marks. The important components of these marks are the UL logo symbols, which are all registered trademarks of UL. The three symbols are used for products of three different services and cannot be mixed, otherwise they can be considered counterfeit products. Due to the rarity of classification marks in China, only two types of marks, namely listing and recognition, will be introduced below. UL's services are not only based on the US UL standards, but also on the Canadian standards (C-UL). Therefore, the UL mark is divided into three types: for UL products and C-UL products, as well as for both,
Note: Prior to January 2008, products listed or recognized by both UL and C-UL could have both UL and C-UL markings affixed. However, by 2008, the markings in the third column of the table above must be used.
The "Inspection Rules" specify which type of mark you are allowed to use and which position this mark should be attached to the product. This logo can only be used if the manufacturer complies with the provisions of the "Inspection Rules" and the terms of the "Tracking Inspection Service Agreement". Unless permitted by the "Inspection Rules", the UL logo cannot be used in any way on products or packaging. (Paragraph 3).
If your product is under one of UL's services and meets UL's requirements, UL allows you to use the UL logo and the name U in your promotional or advertising materials, but this reference must not create a false impression that leads the public. A simple quote stating that a product is "Listed By UL" or "Recognized By UL", or a graphic of the UL logo, is appropriate depending on the service category it belongs to; The words and phrases of the product logo you use should be consistent with those stated in the "Inspection Rules". When your product belongs to UL's classification service, the reference words related to UL in your advertisement must quote the full text of the product classification mark, as stated in the "Inspection Rules". Because UL may require you to change inappropriate places in your promotional or advertising, could you please contact your UL inspection representative in advance and inform them of the way you intend to use the UL logo or name. This can avoid misunderstandings and also prevent the waste caused by UL considering inappropriate references in advertisements and revoking promotional and advertising. (Clause 4).
