Certification IntroductionThe full name of the FCC is the Federal Communications Commission, established in 1934 by COMMUNICATION ACT, it is an independent agency of the U.S. government and is directly accountable to Congress. The FCC coordinates domestic and international communications by controlling radio, television, telecommunications, satellite and cable. Involving more than 50 states in the United States, Columbia and the United States In order to ensure the safety of radio and wire communication products related to life and property, the FCC Engineering and Technology Department is responsible for the technical support of the committee and is responsible for equipment approval. Many radio application products, communication products and digital products require FCC approval to enter the US market. Authentication typeOn November 2, 2017, the FCC merged DoC and Verification into SDoC (Supplier's Declaration of Conformity). SDoC certification will replace the FCC Verification and DoC certification procedures. All equipment applicable to the FCC Verification and DoC certification procedures are taken by SDoC certification procedures. The FCC has two different certification methods for the types of electronic products: FCC SDoC and FCC ID (Certification). The former is suitable for ordinary products without wireless functions, and the latter is suitable for products with wireless functions.Comparison between FCC SDoC and FCC IDFCC SDoCFCC IDApplicable ProductsOrdinary products without wireless functions, such as display screens, lamps, etc.Products with wireless functions, such as mobile phones, Bluetooth headsets, etc.Test contentElectromagnetic Compatibility EMCElectromagnetic compatibility EMC+RFCertification feeLowhightest periodshortlong Applicable product scope1.

Certification IntroductionETL is the abbreviation of ETL Testing Laboratories Inc. It was founded by Thomas Edison in 1896 and is an NRTL (Nationally Accredited Laboratory) accredited by OSHA (Federal Occupational Safety and Health Administration). After more than 100 years, the ETL logo has been widely recognized and accepted by major retailers in North America, and enjoys the same high reputation as UL. The ETL mark is the exclusive mark of Intertek Group, the world's leading quality and safety agency. ETL inspection mark Any electrical, mechanical or electromechanical product with the ETL inspection mark indicates that it has been tested and meets relevant industry standards.Scope of CertificationETL SEMKO is part of Intertek Testing Services Ltd., the world's largest product and commodity inspection organization with 240 laboratories and 469 offices in 93 countries in North America, Europe, and Asia. ETL SEMKO provides testing and certification of product safety, EMC testing, product performance testing, as well as quality management for various industries such as pharmaceuticals, HVAC, appliances, telecommunications, aviation, automation, semiconductors, building materials, energy generation systems, etc. System registration.Any electrical, mechanical or electromechanical product with the ETL inspection mark indicates that it has been tested and complies with the relevant industry standards. Each industry has different testing standards, so be sure to consult a professional for specific product requirements. The ETL inspection mark is widely used in cable products, indicating that the relevant tests have been passed.Approval of electrical products is mandatory in most areas of the United States. ETL refers to ETL Testing Laboratories Inc. ETL's listed products are recognized by "Authorities Having Jurisdiction" and can be considered "approved".The difference between ETL and UL1. Both UL and ETL represent that the product has passed the test of the National Recognized Testing Laboratory (NRTL) and meets the corresponding safety standards.2. ETL certification and UL certification have the same North American market access effect, but the cost of ETL certification is much lower than that of UL certification, generally only half of that of UL certification. Moreover, the product testing of ETL certification can be transferred through CB test report. Save you a lot of testing costs. 3. The lead time of ETL certification is much shorter than that of UL certification. In special cases, ETL can issue a certificate first, and then conduct a factory inspection to save valuable time for the export of your products.4. UL is the most authoritative certification in the United States. On the one hand, UL is an American company, and ITS is a British company.Application informationAt present, there are two ways to obtain ETL certificate, one is to transfer through CB test report, the other is to apply directly. The required documents are as follows: 1. Application form 2. Copy of CB test certificate (not required for direct application) 3. CB test Copy of the report (not required for direct application) 4. Samples (4-8 pieces) 5. Other relevant test results and product data, such as product description, photos, component list, product performance and specifications, circuit schematics, etc. (If you pass the CB report, you need to perform a difference test)The difference between ETL, UL and cTUVus certificationprojectULcTUVusETLuse standardUL2054; UL1642; UL61558; UL62368.1 (the combined standard of UL60950 and UL60065), etc.Certification accreditation bodyUS NRTL (Nationally Recognized Laboratory) and Standards Canada SCCCertification MarketNorth America (US and Canada)Certification and Testing OrganizationUL laboratory tested and issued Notice of Authorization(NoA)ITL test TUV certificationITL test ITS certificationApplication time reference5-12 weeks2-3 weeks2-3 weeksapplication feeMore expensive than the threeThe cost is more favorableThe cost is more favorableAdvantageNative American organization, the most recognized old-fashioned certification organization in the United States and CanadaInternational certification body, authoritative and inexpensive, also recognized by NRTL in the United StatesNative American institutions, highly recognizeddisadvantageBecause it is an old-fashioned institution, the testing, factory inspection and file fees are the highest, and the cycle is long.North American market brand awareness is slightly lower than ULThe North American market reputation is slightly lower than ULotherETLus mark (only us, no c): the safety mark for the product entering the US market cETL mark (only c, no us): the safety mark for the product entering the Canadian market cETLus mark: the safety mark for the product entering the US market and the Canadian market Factory inspection: US ETL certification needs to be checked 4 times a year, Canada is 2 times a year; if there are both, it is 4 times a year.

Certification IntroductionUL is the abbreviation of Underwriter Laboratories Inc. (Underwriter Laboratories Inc.). The UL Safety Laboratory 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, not-for-profit, professional organization that conducts experiments for public safety. Unlike FCC certification, UL certification is a safety certification. UL is mainly engaged in product safety certification and operating safety certification business. Its ultimate purpose is to obtain products with a fairly safe level for the market, and to contribute to the assurance of personal health and property safety. In the United States, UL is the symbol of safety marks for consumers, and globally, UL is one of the most trusted conformity assessment providers for manufacturers.Certification CategoryThe types of UL's product certification and testing services can be divided into listing, recognized and classification.1. LISTED: Generally speaking, listing is only applicable to complete products and various devices and devices that are replaced or installed on-site by qualified personnel. Various products belonging to UL listing services include: household appliances, medical equipment, computers, commercial equipment and various electrical products that function 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: Recognized service is a project in UL service, and the identified products can only be used as components and raw materials on UL listed, graded or other recognized products. Approved products are not structurally complete, or have certain limitations in use to ensure the expected safety performance. Tracking services for approved products fall under the R category in most cases. 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 are required to carry the approval mark.3. Classification: The classification service only evaluates the specific hazards of the product, or evaluates the products that implement other standards than UL standards (including internationally recognized standards, such as IEC and ISO standards, etc.). In general most graded products are not for consumer use, but for industrial or commercial use. The grading mark in the UL mark indicates that the product has certain restrictions and regulations when it is identified by UL. For example, chemicals such as industrial solvents are evaluated only in the range where fire may occur when the temperature reaches the 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 X-ray diagnostic equipment must comply with US laws and related radiation emissions and beams. However, because UL only regards X-ray as a graded product, it only evaluates its mechanical properties, electrical properties and other non-radiative properties.Applicable product scopeElectrical, mechanical or electromechanical productsAny electrical, mechanical or electromechanical product with the UL mark indicates that the product has met the minimum requirements of the generally recognized US and Canadian product safety standards, it has been tested to meet the relevant product safety standards, and it also represents the production plant. Agree to receive strict regular inspections to ensure the consistency of product quality, and can be sold to the US and Canada markets.application process1. The applicant submits relevant company and product informationWritten application: You should request UL in writing to test your company's products. Company Information: Provide the detailed and accurate name, address, contact person, zip code, telephone and fax of the following units in both Chinese and English.(1) Application company: the company that applies for product testing and is responsible for all engineering service costs(2) Listed companies: companies whose names are listed in various product catalogs published by UL(3) Production plants: manufacturers and producers of products.

People make decisions based on the product information provided. When the product information is complete, UL engineers make the following decisions based on the information: UL standards based on the experiment, engineering costs for testing, testing time, number of samples, etc., and notify in writing. You, and send the official application form and tracking service agreement to your company. The fee limit is indicated in the application form, which is the maximum engineering cost estimated by UL according to the testing project. Without the written authorization of your company, the fee limit cannot be exceeded.3. The application company remits and sends back the application form and sample UL certification. The applicant signs the application form and the tracking service agreement, and sends the form back to UL. At the same time, through bank remittance, at the post office or by express mail Please give appropriate descriptions (such as name, model) to the samples sent for inspection. Please send the application form and samples separately. For each application project, UL will assign a unique project number (Project No.) to indicate the project number and the name of the applicant company when remittances, samples and application forms are sent, so as to facilitate UL's inspection.4. After receiving the application form, remittance and experimental samples signed by your company, UL will notify you when the experimental plan will be completed. Product testing is generally carried out in UL laboratories in the United States, and UL also accepts 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 compliance report and a follow-up service procedure (Follow Up Service Procedure). The test report will detail the test situation, the indicators achieved by the sample, the product structure and the safety signs suitable for the use of the product. A description of the product and instructions for UL area inspectors are included in the tracking service specification. 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 to contact the production factory for the first factory inspection (Initial Production Inspection. IPI) in the UL area of China with the UL mark, and the inspector will check the storage of your products and their parts in the production line and warehouse, to confirm whether the product structure and parts are consistent with the tracking service rules. If required in the rules, the regional inspector will also conduct witness experiments. When the inspection results meet the requirements, the applicant is authorized to use the UL mark.The necessity for ULProducts sold in the U.S. market require voluntary UL certification if otherwise specified by laws or regulations. Whether they are products in the U.S. or products exported to other countries, UL certification testing is recommended. We can see many electronic products in the market. All products have the UL certification mark, which is the conduction and radiation test of the product, which is of great significance in the American market. UL certification is an important passport and pass in the American market. Only products with this mark can enter smoothly to the US market.
