Many users are not very familiar with the hot and cold impact test chamber. After all, it is a complex functional testing instrument. Therefore, it will produce various questions at the same time. Today, Kunshan Haida Instrument puts together a number of questions for everyone to help you. A good understanding of the thermal shock chamber.

Question 1: Is the temperature change rate as fast as possible?

Answer: Whether the temperature change rate in the temperature impact test is faster, the better, and the temperature change rate has no effect on the test result. What kind of temperature change rate is the good impact temperature change rate?

Question 2: How to distinguish between temperature shock and temperature cycle?

Answer: Where are the differences between temperature shocks and temperature cycles, or are they just the same?

Question 3: How to determine the residence time of temperature impact test?

Answer: During the impact process, there is a so-called dwell time. How to determine the dwell time of the product to be tested depends on the quantity of the product to be tested or on the material of the test product.

Question 4: Should the rush temperature be over or below the set value?

Answer: In the process of impact, is the impact temperature correct because it is higher than the set value or lower than the set value?

Question 5: Does the temperature sensor of the impact test be placed in the test area or in the air duct?

Answer: The temperature sensor of the impact tester should be placed in the test area or inside the air duct.

Question 6: First flush hot or cold?

Answer: In the temperature impact test, because it is necessary to first flush high temperature or to first flush the low temperature, if the specification does not require it, how to decide?

Question 7: Why do some shocks go beyond normal?

Answer: Why do some shocks go beyond normal temperature, and some shocks do not need to be at room temperature. What impact does the normal temperature impact test have on the product?

Question 8: Can ovens and freezers be used instead of thermal shock machines?

Answer: If you don't have enough money to buy a hot and cold impact machine, can you use the oven and freezer to replace the cold and hot impact machine through manual transportation?

Question 9: How to calculate product life expectancy through hot and cold impact machines?

Answer: Using the thermal shock machine can calculate the estimated service life of the product

Question 10: Problems in the test: What are the main points of holding the product under test?

Answer: To get the product to be tested in the test furnace, how to get it right

Question 11: How long does the test furnace wall need to be wiped?

Answer: How long does the test furnace wall need to be cleaned, whether it is annual maintenance, seasonal maintenance, or weekly maintenance? What happens if it is not rubbed?

Question 12: I want to shorten the test time. What should I do?

Answer: When I conduct a high temperature and humidity test or an impact test, there is no way to shorten my test time, so that the test results are the same.
