Cold and hot impact test chamber common problems summary and solution

Is the temperature variation in the cold and heat shock chamber the faster the better?

Note: Is the temperature variability in the temperature impact test the faster the better? Does the temperature variability have an impact on the test results? What kind of temperature variability is good impact temperature variability?

How to distinguish hot and cold impact testing machine and temperature cycle?

Explanation: What is the difference between temperature shock and temperature cycle, or are they the same but called differently?

How to decide the dwell time of cold and hot impact testing machine?

Note: There is a so-called dwell time in the impact process. How to decide the dwell time of the product to be tested? Is it based on the quantity of the product to be tested or the material of the product to be tested?

Does the impact temperature need to be OVER or below the set value?

Note: In the process of impact, the impact temperature should be higher than the set value, or lower than the set value is correct?

Is the temperature sensor of the impact test located in the test area or in the air duct?

Note: The temperature sensor of impact testing machine, its position should be placed in the test area or inside the air duct?

High or low temperature first?

Note: In the temperature impact test, should high temperature or low temperature be flushed first, if the specification does not require how to decide?

Why do some shocks exceed room temperature?

Explanation: Why some shocks should be too normal temperature, while some shocks do not need to be too normal temperature. What impact does the impact test of too normal temperature have on the product?

Can ovens and freezers be used instead of hot and cold shock machines?

Note: If there is no money to buy the hot and cold impact machine, can you use the oven and freezer through manual handling to replace the hot and cold impact machine

How to calculate the estimated life of the product through the cold and hot impact machine?

The use of hot and cold impact machine can be calculated to estimate the possible service life of the product
