basic introduction
Automobile reliability driving test is to let the car drive on a variety of different roads to comprehensively examine its performance. The various roads used in the test and the mileage of each road surface vary depending on the model, and their requirements are also different. The reliability tests that the car must do include anti-collision test and wear resistance test.

Wenxing test
It is mainly used to evaluate the adaptability of the use and storage of finished products or components under the conditions of constant humidity, temperature and cycle changes in electrical and electronic products, components, materials, etc. It is the most widely used type of artificial accelerated simulation test in products.
Argon lamp test
It uses lights to simulate the destruction of full-spectrum sunlight, and sprays to simulate the effects of rain, dew, exposure, and darkness. Simulate changes in materials exposed to sunlight in different environments. The material samples are exposed to the light of the arc lamp, heat radiation, and humidity to perform the aging test, thereby evaluating the light resistance and weather resistance of the material.
Vibration test
Refers to the evaluation of the vibration resistance of the product in the expected use environment and the test of the physical or model subject to vibration. According to the type of applied vibration load, the vibration test is divided into sinusoidal vibration test and random vibration test.
Sinusoidal vibration test
Including fixed frequency vibration test and scanning sine vibration test. Simultaneous control of temperature and humidity changes on the basis of vibration testing is called vibration three comprehensive testing.

ANATEL certification is a mandatory certification for telecommunications equipment or related equipment by the Brazilian National Telecommunications Administration (Agência Nacional de Telecomunica??es), including wireless communication equipment, wired communication equipment and related auxiliary equipment; this certification ensures that telecommunications equipment sold in the Brazilian market meets Brazil\'s technical standards and regulatory requirements, and guarantees the product\'s quality requirements such as radio frequency, electrical safety, electromagnetic compatibility, and electromagnetic exposure. If the product entering Brazil does not complete ANATEL certification, it may face fines, seizures, and other penalties.
COC certification in Algeria is a mandatory certification for products exported to Algeria, ensuring that the products comply with the country\'s safety, quality, and technical standards. The certification process includes document review, product testing, and factory inspection. Products that pass certification can be legally sold in the local market, protecting consumer interests and promoting fair trade.
GCC certification is the abbreviation for Gulf Cooperation Council certification, which is a mandatory certification requirement for products entering the market in Saudi Arabia and other countries in the Gulf region.
