Based on the standard:
IEC******4(test method)
GB/T ***4.******2(test method change of temperature test guideline)
GB/T ***3.******2 (temperature change)
QC/T****2 (auto parts weathering test general rules)
EIA *****2{thermal shock (temperature cycle) test program electric connector and socket environment impact assessment}
USES: 
Cold and hot impact machine can be used to test material structure or composite material, in an instant by extremely high temperature and extremely low temperature continuous environment can endure degree, in order to in the shortest time test commits any heat bilges cold shrink caused by the chemical changes or physical damage. Applicable objects including metal, plastic, rubber, electronics, pv, solar... And other materials, the products can be used as a basis of improving or reference.
Characteristic introduction:
♦ high temperature groove,low temperature groove,test grove is static.
♦ Shock way uses wind path changing methods,let high temperature and low temperature leading to test area,and reach the high-low temperature shock test goal.
♦Can set rotation times and defrost times. 
♦ Use touching colourful liquid controller,easy to operate,stable.
♦ Temperature accuracy is high,use PID calculating methods.
♦Choose start-move place,high temperature and low temperature is rotation.
♦Showing test curve when operation.
♦Fluctuation two box structure conversion speed, recovery time short.
♦Strong into refrigeration import compressor, cooling speed.
♦Complete and reliable safety device.
♦High reliability design, suitable for *4 hours of continuous test.
