The severity of the high and low temperature test chamber when performing high and low temperature tests depends on the test temperature level and the duration of the test. The relevant standards should be selected from the following values:
Temperature: The test temperature should preferably be selected from the following values: -65, -55, -40, -25, -10, -5, + 5 ° C.
The allowable deviation range of test temperature is ± 3 ℃.
Duration: After the temperature of the test sample has stabilized, if a low temperature test is required for a certain period of time, the duration should be preferentially selected from the following values: 2, 16, 72, 96h, if the purpose of the test is only to check the test sample Whether it can work normally at low temperature, the test time is limited to the temperature of the test sample to stabilize; but in any case, the duration should not be less than 30min.
When this standard is used as the relevant test related to low temperature durability or reliability, the relevant standard requirements for the duration of the test are required.
The high and low temperature test chamber is mainly used to test the product adaptability and reliability of various electronic appliances, optoelectronic communications, LED semiconductors, LCD screen modules, photovoltaic components, plastics, hardware and chemical products after high temperature and low temperature instant impact. To evaluate the performance of the product.
How to choose a suitable high and low temperature test chamber? Which thermal and cold shock test box should be used to test optoelectronic semiconductor products? When buyers and users first touch the device, they often have no idea about how to choose the model and price that suits them. When consulting with the manufacturer, they may not be able to provide you with the most cost-effective due to the unprofessional salesman. product.
The cost of using customers increases, but the product is not satisfactory. It is good to choose the right product.
