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.

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.

Introduction of Japanese PSEPSE certification is a mandatory safety certification in Japan, which is used to prove that electrical and electronic products have passed the safety standard test of the Japanese Electric and Material Safety Law (DENAN Law) or the international IEC standard. Japan's DENTORL Law (Electrical Device and Material Control Law) stipulates that 506 kinds of products must pass safety certification to enter the Japanese market. Among them, 165 kinds of A-type products should obtain the diamond-shaped PSE mark, and 341 kinds of B-type products should obtain the circular PSE mark. From April 1, 2001, "Electrical Products Control Law (DENTORL)" has been officially renamed "Electrical Products Safety Law (DENAN)". Different from the control of contractual regulations in the previous regulatory system, the new system will ensure the safety of products by unofficial agencies. Basic information of PSE certificationMandatory or not: Mandatory Certificate Validity: For diamond, 3-7 years, based on product. For round shape, there is no validity period and no certificate, only VOC Factory inspection requirements can be issued: for diamond shape PSE, only the first factory inspection is required, and there is no annual inspection. For circular PSE, no factory inspection required. Licensee requirements: For diamond PSE, factory/importer. For circular PSE, no requirementTechnical information: Voltage frequency AC 100V, 50Hz /60Hz, plug JIS 8303 Certification classificationAccording to Japan's "Electrical Product Safety Law" PSE certification is divided into two categories.PSE diamond certification: Among them, there are 165 kinds of products that are easy to cause electric shock, fire and other accidents, and are classified as "specific electrical products - called Class A electrical products", such as chargers, adapters, etc.;PSE circular certification: The remaining 341 products with less harmfulness are classified as "non-specific electrical products - called Class B electrical products", most of which are home appliances, lighting products, lithium batteries, etc. Applicable product scopeDiamond PSEElectric wires, wiring appliances, current limiters, transformers, ballasts, electric heating appliances, mechanical appliances for electric power applications, AC electrical machinery appliances, portable generators, other AC machinery appliances, electrical conduits, small AC motors, light sources and light sources Applied mechanical appliances, batteries, etc., belong to the scope of products stipulated by the specific electrical appliances safety law, such as: DC power supply devices, switches and sockets, electric water heaters, power cords and plugs, other household appliance transformers (AC-AC power supply products), etc. 165 products. Circular PSEThe scope of products that fall outside the specific electrical appliance safety law, such as: electric blankets, electric steamers, electric hair irons, electric ovens, microwave ovens, hair humidifiers, refrigerators, electric mixers, electric egg cookers, electric insulation basins , hair dryers, electric humidifiers, projectors, washing machines, incandescent light bulbs, fluorescent lamps, desk lamps, decorative lamps, advertising lamps, lithium batteries and all LED bulbs and LED lamps and other 341 products.Certificate validity periodDiamond PSE certificate: 3 years, 5 years, 7 years (depending on the product) Circular PSE certificate: usually self-declared by the factory or a test report issued by a third-party laboratory/certification agency

Certification IntroductionThe certification of radio frequency equipment in Japan is called Radio Equipment Type Approval. The official control agency is the Ministry of Internal Affairs and Communications of Japan. The main certification agency is TELEC (Telecom Engineering Center) designated by MIC, and RF Technologies /JQA/SGS/ITS/TUV/UL, etc., a total of 12 certification agencies, so it is usually called TELEC certification, also known as MIC certification, RF certification, GITEKI certification, technology certification, similar to the domestic SRRC certification.TELEC certification follows Japan's "Radio Law" (Radio Law), and the specific test specification follows the MIC (Ministry of Internal Affairs and Communications) Notice No.88 regulations. According to the requirements of Japan's "Radio Wave Law", the production, sale and operation of wireless equipment in Japan must comply with the technical regulations approved by MIC, and it is mandatory to apply for radio equipment type approval certificate (ie TELEC certification). Whether the basic information of TELEC certification Is mandatory: mandatory certification Factory inspection requirements: no requirements, but ISO certificates or accredited quality control documents are required For certificate holders: no requirementsCertificate validity: noneCertification period: about 4 weeks Technical information: Voltage frequency AC 100V/200V, 50Hz/60Hz, plug JIS 8303 Description of TELEC certification, GITEKI certification, MIC certification and MARK technology certification · TELEC certification and GITEKI certification The full name of TELEC in Japan is TELECom Engineering Center. It has obtained the certification qualification of the "Electrical and Telecommunications Business Law", and now generally speaking, TELEC certification is equivalent to GITEKI certification. ·TELEC certification and MIC certification The Japanese Ministry of Internal Affairs and Communications is referred to as MIC, and the English full name is Ministry of Internal Affairs and Communications. The Ministry of Internal Affairs and Communications is the regulatory agency of Japan's "Radio Wave Law" and "Electrical Communication Business Law". Generally speaking, MIC certification is equivalent to TELEC certification. ·TELEC certification and MARK technology certification After passing the TELEC certification, the product can be printed with the GITEKI logo. GITEKI comes from the Japanese name for certification: "Technology マーク", the Japanese word technology is spelled GITEKI in Roman characters, so GITEKI certification is also called For technical fitness certification, GITEKI certification and technical fitness certification are just different names. Certification classificationTELEC certification includes Test Certification and Type Certification. The test certification is verified for each equipment unit, and the certification is only valid for each verified equipment unit;Type approval refers to the verification of a sample of a batch of equipment of the same design and manufacture. The certification is valid for the batch of equipment, but if the design or manufacture of the equipment has changed, the equipment will need to be re-certified. It is worth noting that the use of non-low power radio stations and their terminal equipment requires a license from the MIC. In addition, there are two types of compliance certification for telecommunications terminal equipment: · For ordinary telephone devices, only JATE certification is required in accordance with the requirements of the Telecommunications Business Law; · For wireless terminal equipment, in addition to the need for JATE certification according to the requirements of the Telecommunications Business Law, TELEC certification is also required as required by the Radio Law. Applicable product scopeTELEC certification for wireless radio frequency products include: Bluetooth products, ZigBee products, telemeters, WiFi products, wireless microphones, pagers, LTE RFID (2.4GHz, 920MHz) products, UWB radio systems, GSM products, etc. otherBluetooth and WIFI product testing requirements The test certification is verified for each device unit, and the certification is only valid for each verified device unit; the test items of WiFi and Bluetooth products are basically similar to the European standard EN300 328. Among them, 2.4GHz WiFi products (802.11b /g, 2412~2472 MHz) and Bluetooth products use the standard MIC Notice No.88 Annex43, but for 14 channels (Channel 14: 2471 ~ 2497MHz) of 2.4GHz WiFi products, you need to use Annex44 for testing and reporting. The corresponding fee also needs to be increased. For 5GHz WiFi products (802.11a, 5180~5320MHz, W52 Band and W53 Band), the test standard to follow is Annex45, but it should be noted that the data shows that MIC will modify Annex45 in the near future. It is classified into Annex45 and has stricter DFS test requirements for Band 56 frequency band. Bluetooth product test content1. Frequency Error Measurement 2. Occupied Bandwidth and Spread-spectrum Bandwidth / Factor 3. Unwanted Emission Intensity Measurement 4. Antenna Power Error Power Error Measurement) 5. Limitation of Collateral Emission of Receiver Measurement 6. Transmission Antenna Gain (EIRP Antenna Power) Measurement 7. Transmission Radiation Angle Width (3dB Beamwidth) Measurement) 8. Duty Cycle Measurement 9. Retention time

Certification IntroductionJATE (Japan Approvals Institute for Telecommunications Equipment) certification is a compliance certification for telecommunications equipment. This certification is for communication equipment in Japan to ensure that the equipment complies with Japan's "Electrical Communication Business Law". All wireless products connected to public telephone or telecommunication networks must apply for JATE certification. Simply put, JATE certification is Japan's network access certification. JATE certification is a mandatory certification for Japanese public network telecommunication equipment. Japan's Ministry of Public Administration and Internal Affairs, Posts and Telecommunications (MPHPT) stipulates in Japan's Telecommunications Business Law that Japanese telecommunications equipment implements compulsory certification. The Telecommunications Business Act, established in 1985, stipulates in Article 68 that the MPHPT authorizes qualified agencies to implement qualified accreditation of technical conditions. MPHPT authorizes JATE (Japan Approvals Institute for Telecommunications Equipment) as a qualified agency to implement accreditation, so we are used to calling Japan telecommunications equipment certification JATE certification. JATE accreditation requires the certification mark to be affixed on the product, and the certification mark uses the serial number. Approved products, applicants, products, certification numbers and other relevant information will be announced in the Government Gazette and JATE's website. Generally speaking, telecommunications products entering the Japanese market must meet the testing requirements of Japan's "Telecommunication Law" (JATE certification) and "Radio Wave Law" (TELEC certification). JATE certification mark basic information of JATE certification is mandatory: Compulsory certification validity period: no validity period Factory inspection requirements: no requirements Certificate holder requirements: no requirements Technical information: voltage frequency AC 100V/200V, 50Hz/60Hz, plug JIS 8303  The differences between JATE and TELEC certification are:The scope of control is different: JATE certification is for communication equipment, TELEC certification is for radio equipment;The test content is different: JATE certification test signaling interaction test, TELEC certification is generally radio frequency test;The label characters are different: those with 'T' characters are JATE certification, and those with 'R' characters are TELEC certification, as shown in the figure: Certification classificationThere are two types of JATE certification: 1. Technical Conditions Compliance Certification Technical conditions compliance certification includes type approval and stand-alone certification. Technical condition compliance certification ensures that telephone network equipment, wireless calling equipment, ISDN equipment, leased line equipment, etc. can meet the technical requirements (terminal equipment related regulations) formulated by MPHPT. 2. Technical Requirements Compliance Certification (Technical Requirements Compliance Certification) Technical requirements compliance certification includes type approval and stand-alone certification. Technical requirements compliance certification ensures that wireless calling equipment, leased line equipment and other telecommunication equipment can meet certain technical requirements, which are formulated by telecom operators authorized by MPHPT. Applicable product scopeCommunication equipment in Japan today requires JATE certification, such as: telephone network equipment, wireless calling equipment, ISDN equipment, leased line equipment, wireless calling equipment, leased line equipment and other telecommunication equipment. Test contentJATE certification requirements for mobile communication equipment, including the following protocol test content:1.Basic functions2.Calling functions (other calling functions)3.Transmission timing4.
