Automotive Electronics EMC Testing
With the continuous development of electromagnetic compatibility technology in China, a large number of electronic devices are integrated in a small car space, such as navigators, car audio, reversing radar and airbags and other electronic integrated systems. Interfering signals in different bands. For example, when driving under the high-voltage power line, the operation is invalid due to the interference of the on-board electronic control circuit, which affects the experience of the driver and passengers, and causes the accident of car crash and death. Therefore, the relevant testing of automotive electronics plays an increasingly important role in ensuring the safety of automobiles. Lanya Testing Automotive Electronics Laboratory has complete test sites and test equipment, and has a professional technical team to escort your products and provide you with professional and reliable testing services.1. Introduction to EMC testing of automotive electronicsElectromagnetic Compatibility (Electromagnetic Compatibility, EMC). Refers to the ability of a device or system to work normally in its electromagnetic environment without causing unacceptable electromagnetic disturbance to anything in the environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment during normal operation cannot exceed a certain limit, that is, the so-called electromagnetic interference (Electromagnetic In...

E-mark certification
Lanya Testing is a professional testing and certification company in Shenzhen. The self-built automotive electronics laboratory has complete in-vehicle testing and certification capabilities, providing convenient and fast E-mark certification and CE certification (EN50498).1. Introduction and mark of E-mark certification1. Introduction of E-mark certificationE-Mark/e-Mark is the European common market. For automobiles and motorcycles and their safety spare parts, noise and exhaust gas, etc., product certification is carried out in accordance with the regulations of the European Union [EEC Directives] and the Regulations of the Economic Commission for Europe [ECE Regulation]. The certificate of conformity granted by the party to ensure the safety of driving and the requirements of environmental protection.2. E-mark certification markEurope has safety certification requirements for motor vehicles and safety-related components and systems, which are embodied in the E-mark and e-mark certification.One of the E-Mark/e-Mark certification marks is a round frame; the other is a rectangular frame, which represent different meanings.The E mark originates from the Regulations promulgated by the Economic Commission of Europe (ECE). It is the European market for automobiles, locomotives and their safety spare parts, noise and exhaust gas, etc., all need to pass the product certification requirements in accordance with the provisions of the European Union Directives (EEC Directives) and th...

Audio Test EN50332 Sound Pressure Test
1. What is the EN50332 test?As we all know, listening to music at high volume for a long time will cause damage to the ears. EN50332 is to prevent this damage. EN50332 specifies the sound pressure, output voltage and audio stability tests of portable playback devices. The scope of its testing includes all portable audio equipment with earphones or earphone jacks and separate earphone products that need to be tested to EN50332.Second, the test classification of EN50332 EN50332 is divided into two parts, EN50332-1 (the sound pressure test of the whole machine) and EN50332-2, and EN50332-2 is divided into EN50332-2-1 (player output voltage), and EN50332-2-2 (earphones) Broadband characteristic voltage test). EN50332-1 includes a measurement of the maximum sound pressure level for the performance of the player when used with headphones, and EN50332-2 includes two tests for the maximum output voltage of the player and the broadband characteristic output voltage of the headphones. The standard stipulates that the measurement of the maximum sound pressure level needs to be repeated five times, and the headphones need to be removed and re-fixed each time. The average value is the final test result, and the maximum sound pressure level cannot exceed 100dB. The maximum output voltage is the unweighted effective value measured by loading the electric signal of the headphone port of the player on a 32Ω load, and the average time is more than 30s. Wide Band Characteristic Voltage (WBCV)...
