Selection principle and use cautions of cold and hot shock box equipment
2019-02-11 23:12:04
When using the hot and cold shock box, it is necessary to pay attention to check the power supply before use, and it is necessary to have a good grounding wire to ensure the safety of the product equipment. In the case of cold and heat shock box equipment, some flammable items and items with relatively high volatility may not be put into the cold and hot shock box for testing.
Do not make any changes to the components inside the cold and heat shock box device to prevent some failures and affect the service life of the device.
The inside of the box is cleaned and necessary maintenance is performed periodically.
When checking the maintenance of the thermal shock box, it is necessary to cut off the power supply to prevent electric shock.
The selection of environmental testing equipment is based on simple facts. The main selection criteria are the test specifications and test standards for engineering products and some principles. The same applies to cold and heat shock box equipment. The five principles that need to be followed include reproducibility, reproducibility, measurable control, exclusiveness, and safety and reliability.
The reproducibility is that a cold and thermal shock box environmental test equipment may be used for multiple tests of the same type of product, and a tested engineering product may also be tested in different environmental test equipment and be subjected to a cold and heat shock box. The stress level of the test product (such as thermal stress, vibration stress, electrical stress, etc.) is consistent with the requirements of the same test specification.
The controllability is measurable; the environmental conditions provided by any environmental cold and thermal shock box test equipment must be observable and controllable. The accuracy of the general requirements for parameter testing in various test specifications should not be less than the allowable error of the test conditions. One-third.
Safety and reliability of test equipment: Various protection and alarm measures and safety interlock devices for cold and heat shock box test equipment should be perfect and reliable to ensure the safety and reliability of test personnel, tested products, and test equipment for cold and heat shock box. Climate chamber. The environmental test equipment must have the characteristics of safe operation, convenient operation, reliable use and long working life.
Exclusivity: Each time an environmental or reliability test is performed, the thermal shock box has strict rules on the types, magnitudes, and tolerances of environmental factors, and excludes environmental factors that are not required for the test to penetrate them so that the After the end of the test, it provides an accurate basis for judging and analyzing product failure and failure modes.
