Common failure analysis plan for hot and cold shock test chamber
Question 1: Is the temperature change rate of the cold and hot shock test the faster the better?
Explanation: Is the temperature change rate in the hot and cold shock test the faster the better? Does the temperature change rate have any effect on the test results? What temperature change rate is the good impact temperature change rate?
Question 2: How to distinguish between thermal shock and temperature cycle?
Explanation: What are the differences between cold and hot shocks and temperature cycling, or are they the same but just different names?
Question 3: How to determine the residence time of the thermal shock test?
Note: There is a so-called dwell time during the impact process. How do you determine the dwell time of the product under test? Does it depend on the number of products under test or the material of the product under test?
Question 4: The impact temperature needs to be OVER or lower than the set value?
Explanation: During the impact process, should the impact temperature be 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?
Note: Should the temperature sensor of the impact testing machine be placed in the test area or the air duct?
Question 6: First flush high temperature or low temperature first?
Note: In the hot and cold shock test, should the high temperature or low temperature first be washed? How to decide if the specification does not require it?
Question 7: Why do some shocks have to go beyond normal temperature?
Explanation: Why do some impacts need to exceed normal temperature, while some impacts do not need to exceed normal temperature, and what impact does the impact test over normal temperature have on the product?
Question 8: Can the oven and freezer be used to replace the hot and cold impact machine for testing?
Note: If you do not have enough funds to buy a hot and cold impact machine, can you use the oven and freezer to manually replace the cold and hot impact machine?
Question 9: How to calculate the estimated life of the product through the hot and cold impact machine?
Note: The use of hot and cold impact machine can calculate the estimated life of the product
Question 10: The question in the experiment: the main points of holding the test product?
Note: How to get the test product in the test furnace
Question 11: How often does the test furnace wall need to be wiped?
Description: How long does the test furnace wall need to be wiped, whether it is annual maintenance or seasonal maintenance or weekly maintenance, what will happen if it is not wiped
Question 12: What should I do to shorten the test time?
Note: When I conduct a high temperature and high humidity test or an impact test, is there any way to shorten my test time and make the test results the same?
