The significance of conducting temperature rising test
In our daily life, we cannot live without various electronic products. While these products bring us convenience, they also carry certain risks. In order to ensure the safety performance of electronic products, it is necessary to conduct safety assessments. As an important tool for safety assessment of electronic products, the temperature rise test corner can accurately measure the heat release and temperature distribution of electronic products. The black test corner is an important tool for safety assessment of electronic products.
What is black test corner?
Temperature rising test corner also be called as black test corner, due to the test corner is made of dull black painted plywood. The plywood has approximately 20mm thick. And thermocouples used for determining the temperature rise are attached to the back of small blacked disks of copper. The temperature rising test system mainly consists of a test corner, thermocouples, multiplex temperature meter and etc.. Place the electronics device in the test corner, and then set the corresponding test conditions according to more practical needs, such as heating time, heating power, heating voltage/current. When the EUT reaches the working state, the thermocouples will measure the temperature of EUT in real time, then surface temperature will be recorded by temperature meter. After complete the test, the surface temperature rise value of the electronic product is calculated and compared with the standard requirements like the table 3 of standard IEC60335-1.
The application of temperature rise test corner can help to know the heat release and temperature distribution of electronic products. So that to ensure that product safety performance meets standard requirements. And eliminate unqualified products and improve product quality stability. And provide scientific basis for product improvement and optimization, improve product safety performance and user experience.
