FAQ
Q1: What is the difference between thermal cycling and thermal shock testing?
Thermal cycling involves gradual temperature transitions, while thermal shock involves rapid transfer between extreme temperatures.
Q2: How is temperature uniformity ensured?
Through forced air or liquid circulation combined with calibrated control systems.
Q3: When is a pressurized system required?
For testing components such as pipes or sealed systems under combined temperature and pressure conditions.
Q4: What are the key selection criteria?
Temperature range, chamber volume, pressure requirement, and test standards compliance.
