The three slot cold and hot shock test chamber is used to assess the ability of products (whole machines), components, parts, etc. to withstand rapid temperature changes. This temperature shock test can understand the impact of temperature changes on the test sample once or continuously multiple times. The main parameters that affect the temperature change test are the high and low temperature values within the temperature change range, the holding time of the sample at high and low temperatures, and the number of cycles of the test. Generally used in a wide range of fields, from research and development to inspection and production.
Low temperature impact principle
After lowering the temperature of the low-temperature box to the set value through the refrigeration system, open the cylinder damper of the low-temperature box, and use the circulating fan to send low-temperature air into the test box, causing the temperature of the test box to rapidly drop to the set value, thereby achieving low-temperature shock.
Thermal shock principle
The air is heated by a heating wire, and the heat is sent to the testing box through the high-temperature box damper by a circulating fan, causing the temperature of the testing machine to rapidly rise to the set value and complete the high-temperature test.
Test Standard
Meet GB/T2423.22 (1IEC60068-2-14); IS016750; Temperature shock test in series standards such as IPC-TM-650.
