Project Introduction
Damp heat test includes constant damp heat test and alternating damp heat test. The high and low temperature alternating humid heat test is an essential test item in the fields of aviation, automobiles, home appliances, scientific research, etc. It is used to test and determine the temperature environment of electrical, electronic and other products and materials for high temperature, low temperature, alternating humid heat or constant test The changed parameters and performance.
For example: the temperature difference between day and night, different humidity at different temperatures and different times, the product passes through regions with different temperatures and humidity during transportation. This alternating temperature and humidity environment will affect the performance and life of the product and accelerate the aging of the product. If you are in this environment for a long time, the product needs to have sufficient resistance to alternating heat and humidity.

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.
