Temperature and Humidity

Providing rapid temperature change rates to test specimen and use different levels of humidity to locate design defects so as to improve product quality and reliability.

Temperature Shock

Test the resistance of the specimen due to sudden changes in temperature. Specimen undergoes specified number of cycles from ambient temperature to extremely low temperature before expose to extremely high temperature. 

Vibration Test

Determine the effect of fatigue or degradation in the performance of the specimen structure through vibration analysis of test specimen such as free versus forced vibration, sinusoidal versus random vibration, and linear versus rotation-induced vibration.
