Thermal shock test chamber is used to test products in alternating extremes of high and low temperatures in order to observe changes in product characteristics and failure occurrence.
QT3 series air-to-air thermal shock chambers circulate cold, hot, or ambient air as needed. The conditioned air is pre-cooled or pre-heated beyond the set point, allowing quicker recovery of the desired condition after transfer.
QT3 Series Chambers Conform Following Testing Standards:
MIL-STD-883E Method 1011.9 Thermal Shock
MIL-STD-202G Method 107G Thermal Shock
JIS C 0025 Basic Environmental Testing Procedures Part 2: Tests, Test N: Change of Temperature
IEC 61300-2-47:2004 Fiber Optic Interconnection devices and passive components-Basic Test and Measurement Procedures – Part 247: Tests – Thermal Shocks
JEDEC STANDARD JESD22-A104C Temperature Cycling
