Description: Introduce the current hot and cold impact environment test, the user is using the environmental test equipment, and the problems and problems often encountered in the specification requirements. If you have the following related questions, welcome to the business department, we will be happy to help you. . :
Question 1: Is the temperature change rate of the temperature shock test as fast as possible?
Explanation: The temperature change rate in the temperature impact test is as fast as possible. The temperature change rate has no effect on the test results. What kind of temperature change rate is the good shock temperature change rate?
Question 2: How to distinguish between temperature shock and temperature cycle?
Explanation: Where is the difference between temperature shock and temperature cycle, or is it just the same?
Question 3: How is the residence time of the temperature shock test determined?
Note: There is a so-called dwell time during the impact process. How does the dwell time of the product to be tested depend on the quantity of the product to be tested or the material of the product to be tested?
Question 4: Does the impact temperature need to be OVER or lower than the set value?
Note: During the impact process, is the impact temperature correct if it is higher than the set value or lower than the set value?
Question 5: Is the temperature sensor of the impact test placed in the test area or in the air duct?
Description: The temperature sensor of the impact tester should be placed in the test area or in the air duct?
Question 6: Do you want to rush high temperature first or low temperature first?
Note: In the temperature impact test, it is necessary to first rush high temperature or first to cry low temperature, if the specification does not require it, then how to decide?
Question 7: Why do some shocks have to be normal?
Note: Why do some impacts have to be normal temperature, and some impacts do not need to be normal temperature, what effect does the impact test after normal temperature have on the product?
Question 8: Can the oven and freezer be used to replace the thermal shock machine for testing?
Note: 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 hot and cold impact machine by manual handling?
Question 9: How to calculate the estimated life of the product through the thermal shock machine?
Description: Use the thermal shock machine to calculate the estimated service life of the product.
Question 10: Problems in the test: What are the main points of holding the test item?
Explanation: To take the test item into the test furnace, how to take it correctly
Question 11: How long does it take to test the furnace wall?
Description: How long does it take to test the wall of the furnace? Is it annual or quarterly or weekly? If not, what will happen?
Question 12: What do I want to do to shorten the test time?
Note: When I am conducting high temperature and high humidity test or impact test, is there any way to shorten my test time and make the test result the same?
