Today, with the increasing development of international trade, the differences in technical standards among countries have become a major challenge that hinders the circulation of electronic and electrical products. The primary task for the import and export of electronic and electrical products is to solve technical trade barriers. As a product with a significant impact on public life in the world today, the environmental protection and safety of electronic and electrical products are increasingly becoming a focus of public attention. Electronic and electrical product testing is a test conducted on harmful substances and product performance in products to determine whether they comply with relevant standards and specifications of various countries. It is an important way to solve technical barriers to import and export trade. After electronic and electrical products are discarded, the toxic and harmful substances contained in them cause great pollution to the soil and water, and the toxic gases generated by garbage incineration pose a threat to the atmosphere and human health. The scope of electronic appliance testing ITE: household appliances, audio and video products, lighting fixtures, wireless communication, medical devices, power supplies, energy efficiency testing, battery testing, railway applications, electromagnetic compatibility, product safety testing, mobile phones, connectors, automotive electronics, radiation testing, and other household appliances: household appliances, electric tools, adjustment controllers using semiconductor devices, electric motor driven electrical, medical equipment, electric toys Vending machines and movie or slide projectors. Equipment that does not fall within the scope include devices that explicitly state all emission requirements within their RF range in other standards, such as lighting fixtures, power grid communication devices, etc; Audio and video products: With the progress of science and technology and the development of society, people's pursuit of spiritual entertainment is also becoming more diverse and colorful. Various entertainment facilities, such as radio and television receivers, digital televisions, and home audio systems, are increasingly emerging, and the electromagnetic environment is becoming increasingly complex and deteriorating. Luminaires: The Luminaire Laboratory focuses on safety and energy efficiency testing of lighting products. An independent and complete testing center has been established in Shenzhen, with six major laboratories including photoelectric performance testing, lamp safety testing modules, and lamp light distribution curve testing, environmental testing, electromagnetic compatibility testing, and harmful substance testing. Wireless communication: With the rapid development of technology, wireless communication products have been widely applied in various industries and fields, and the quantity and types of exported products are also diverse. How to meet customer requirements, pass certification smoothly, and quickly seize the international market has always been a concern for various manufacturers. Medical equipment: There are relatively strict requirements for medical products entering various countries, and the EMC part only belongs to the requirements of the safety parallel standards for exported medical machinery products. Energy efficiency testing: With the increasingly prominent global energy crisis and environmental issues, the call for energy conservation and environmental protection is also increasing. Many countries are accelerating the development of a new round of energy efficiency plans to help better control product energy consumption, save costs, protect the environment, and enhance market levels. Battery testing: From hybrid motors to personal electronic devices, to renewable energy, we have extensive experience in ensuring that your battery and energy storage technology meet relevant performance, reliability, and safety standards. We also have various battery testing instruments, and for batteries with different chemical compositions and specifications, we are in the field of battery testing and certification. Specific testing items for electronic appliances: EMC electromagnetic compatibility test: The testing content includes information technology equipment, lighting fixtures and rectifiers, audio, power transformer video and similar equipment, power supply devices and similar products, uninterruptible power supplies, lithium batteries, and electromagnetic compatibility. The main testing items include EMI electromagnetic interference test, power line conducted disturbance, etc. EMS electromagnetic immunity test: The testing content includes electrostatic discharge immunity, electrical fast transient pulse group immunity of power port, electrical fast transient pulse group immunity of signal line and control line, coupling and transient immunity of power line conduction, transient immunity of signal and control line conduction space coupling, radiation field immunity of small room, surge of signal line and control line, shell radiation immunity The immunity of transverse electromagnetic waves and current injection, as well as the immunity of strip lines. Chemical testing: The testing content includes six ROHS tests, tetrabromobisphenol A tests, halogen tests, PFOS (perfluorooctane sulfonic acid)/PFOA (perfluorooctanoic acid) tests, alkylphenol polyoxyethylene ether, phthalate ester tests, polybrominated biphenyls, etc. ROHS testing: Detects the pollution of electronic and electrical waste to the ecological environment, and prohibits six categories of harmful substances from electronic and electrical products in the EU market. Other testing: Specific testing items include protection against contact with live parts, leakage current, electrical strength, insulation resistance, grounding resistance, input power and current, creepage distance and electrical gap, dust prevention, solid foreign object prevention, waterproofing, lamp power, power factor, luminous flux, illumination, harmonics, electromagnetic compatibility immunity, and photobiosafety; Electromagnetic compatibility testing includes radiation disturbance, conducted disturbance, electrostatic discharge, harmonics, voltage changes, voltage fluctuations, electrostatic discharge immunity, radio frequency electromagnetic field radiation immunity, electrical fast transient pulse group immunity, surge (impact) immunity, radio frequency field induced conducted disturbance immunity, voltage sag, short-term interruption and voltage change immunity, and power frequency magnetic field immunity; Environmental reliability, life assessment, aging testing (UV, lamp, carbon arc lamp, ozone), salt spray test, oil resistance and other liquid tests, high and low temperature impact, high and low temperature cycling, constant damp heat test, alternating damp heat test, impact test, collision test, free drop test, vibration test; The above article is a partial list of electronic and electrical testing processes.
