Project Introduction
The rapid temperature change test is used to determine the product's adaptability to storage, transportation, and use in a rapidly changing climate with high and low temperatures. The test process generally takes normal temperature→low temperature→low temperature stay→high temperature→high temperature stay→normal temperature as a test cycle. Verify the functional characteristics of the sample after the temperature change or continuous temperature change environment, or the operation functionality in this environment.
The rapid temperature change test is usually defined as a temperature change rate of ≥3°C/min, which changes between a certain high temperature and low temperature. The faster the temperature change rate, the larger the high/low temperature range, the longer the time, the stricter the test. The temperature shock usually affects the part close to the outer surface of the equipment more seriously. The farther away from the outer surface, the slower the temperature change and the less obvious the effect. Transport boxes and packaging will also reduce the impact of temperature shocks on enclosed equipment. Rapid temperature changes may temporarily or permanently affect the operation of the equipment.
Testing purposes
Evaluate the storage or workability of products under temperature changes. The purpose of the qualification test is to check whether the product meets the requirements of the relevant standards; the improvement test is mainly used to assess the durability and reliability adaptability of the product under temperature change conditions.
Application range
The rapid temperature change test is widely used in electronic and electrical, vehicles, medical, instrumentation, petrochemical and other fields, complete machines, components, packaging, materials, etc.
Method Standard
Test standard reference: GB/T 2423.22, IEC 60068-2-14, EN 60068-2-14.
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.
