Apply for UL certification note UL certification body

Apply for UL certification matters needing attention
The UL engineers understand you to test the product category, product performance, application and working environment
A ) to test the products, it seems quite simple, but due to the language barrier, in the repeated translation or translation often leads to a beat all results. Cite a simple example, Zhejiang has a factory to apply for" Harness" (with various wires and terminals, insert assembly ) of the UL certification, Zhejiang area used to call" Harness" for" connector". If you open the dictionary, you'll find out" connector" English "Connector". The factory is the application of the " Connector" certification, spent a lot of time and energy, the results of course one can imagine, allowing only the factory production of" terminal" ( including the metal insert and the outside of the plastic parts ) with UL markers, and wire harness. In fact, the factory all the" terminal" ( Connector ) are bought. Therefore, in the application of authentication when should ensure that the product name is correct, unless you are one hundred percent sure, UL online recommend you prior to the UL offices in China to confirm the product name in English, this is one of the responsibilities of the office of.
B ) with a product, if the potential use of not the same, the testing method is not the same. For example the same string of Christmas lights ( DecorativeLightingStings ), used for indoor and outdoor has the very big difference, a bit simple, indoor lamp string without rain test, while the outdoor lamp string is a must. For example, if your production base for 110V voltage, you need not let it according to 220V requirements to test. This shows that there is no need to expand the use of the products you, unless you intend to put your products to the new conditions. In contrast, nor narrow applicable scope. If your production of plastic for 105 degree environment, in order to save costs, you only apply for 90 degree environment, although your products through the UL certification, but your customers cannot use it as UL products for 105 degree environment. This is of course you don't want to see. Therefore, to make your product range, so as not to waste your time and costs, to bring you unnecessary loss. For the electrical, electronic products, the range of use is mainly the voltage, current, power factor, environment temperature etc. If you are not very familiar with the range of use, please get in touch with your engineer.
Illustrate the difference between the different types
If you have a variety of models of similar products applied for certification, or you have similar products for the UL certification, please specify the types of the same and different points between, this can help UL engineers decided to reduce the unnecessary duplication of testing to reduce your costs and test time. For example, there are two types of relays to apply for certification, is a group of contacts, and the other is two points, then the engineer during the test only on the second models of the product of another set of contacts to be paid special attention to, and need not be repeated for all test.
For your product to a list of raw materials or spare parts list
UL certification body is mainly through the control of the products of various raw materials or components approach to the control of the entire product. Therefore, it requires the customer to submit product when the parts of the source. These parts once confirmed, can not arbitrarily change, if you want to use other plant other substitute, must obtain prior approval from UL agreed to and the possibility of your products tested again. Otherwise, the UL inspector will find you the trouble. In preparing this list when there are certain tips: first of all, you should be on the list that your parts suppliers, the number of models, the main indicators and certification bodies. If your widget is recognized by the UL, the best applicant UL file number ( FILENUMBER ), which can be removed from the many to the components of the test. Again, for some of the key components, a selected few suppliers, UL will bring these eligible products are included in the follow-up inspection rules. In this way, when you want to change to a supplier, will not be because UL rules and regulations and cause unnecessary trouble. You can refer to the following table is a list of. ( for the convenience of your reading, the following table uses the Chinese, in the product is submitted to the UL process, please use the parenthesis in English
Part name ( Component ) number ( No, ) manufacturers ( Manufacturer ) model ( ModelNo, main index ( Ratings ) certification body ( Certification )
Shell ( Enclosure ), U-12105C94V-0UL 1ActiveCorpLtd ( E170432 )

Although many people think in this list is more ambiguous as possible, because it can be reduced to their limit. Maybe this is a kind of skill, but its side effect is UL Engineer may write to you again, let you specify certain components suppliers, at this point, you have no choice. Do you not only has no benefit, but to delay your time. UL online only in favour of robust techniques.
List all of your production site
If you in several different places of production the application product, please tell UL all the factory name and address. UL only authorized specific address specific plant using UL markers. One plant in different address of the factory, or different address collaboration plant, need to make and UL, with UL signed tracking inspection service agreement, and the inclusion of track inspection service rules, otherwise, the other using the UL marking the production location for illegal production. UL has the right to ask the Chinese law severely punished.
With the UL certification body to maintain good ties
UL received in the laboratory customers after submission of the application, will make the following work, please in the application process to confirm the various steps of: customer advisers will reply to the customer, confirm the receipt of your application, and notify you assess products with UL standards and is responsible for the delivery test product engineering team leader the name.
In the UL engineer received all the necessary technical information and formulate good product inspection plan, UL will send a letter to customers, including brief introduction of the scope of the inspection, the required sample name and number, test cost estimates and prepayments. With a formal application form.
Application form in two copies, including product name, model, listing the name and address, the manufacturer's name and address, name and address of the applicant, the applicant 's file number, the project is expected to end date and maximum cost number etc.. Application form basically is the applicant and UL test chamber between the formal agreement or contract. It includes the terms of the agreement, the parties in the closed and products etc..
Customers in the received UL certification body with your application form, we must take the following steps:
To fill in and by units of the signature of the person in charge of an application form and send back to the UL engineers responsible for the project, another factory as a file
The advance payment sent to UL or telegraphic transfer to UL throughout the United States bank account, and will send or fax the remittance voucher to the corresponding UL engineer.
The application to check samples to UL project close to. Please specify the UL project engineer 's name, the name of the applicant, the file number, item number, type and quantity of the sample. Samples can be taken directly from the production line or is a production of the products, can also be produced sample. But these samples using the components and materials and formal production product of the same.
In UL all of your products and the related letters, please specify the file number ( FILENUMBER ), if it is in the process of testing, please indicate the project number ( Project Number ), which can help engineers to quickly, correctly deal with your letter.
In the testing process, the client will receive" tracking the inspection agreement". If there are multiple manufacturers involved in the production of similar products, will receive multiple copies of the agreement. Agreement with the manufacturer's name, in two copies. " Tracking the inspection agreement" should be made by the manufacturer responsible person or authorized person signature and return UL test chamber. UL certification body in one copy and return to the factory. This is the factory and UL signed between the inspection contract, has the force of law, should be properly kept.
If the UL certification body to your factory in the production line and testing equipment have certain requirements, UL certification body will be sent to the factory to check and accept, and therefore should be prepared in advance and the necessary equipment, as to which equipment to need, usually at the beginning of the project, the engineer will inform the factory, without this information, usually there is no requirement.
