Test Background
The air pressure test is divided into high air pressure test and low air pressure test, which are used to determine the adaptability of the detector for use under low or high air pressure. If the nuclear radiation detector is exposed to too high or too low pressure, the performance of the product may easily decline or the operation may become unstable.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various nuclear radiation detectors, and provides professional low-pressure testing, high-pressure testing and other environmental testing services for nuclear radiation detector products.
Test method
Low pressure test:
During the test, the test sample is in a non-working state. Place the pretreated test sample into a test chamber under normal atmospheric conditions, then reduce the air pressure in the test chamber to the specified pressure value, and expose it to this condition for the specified duration. The average rate of air pressure adjustment in this test should not exceed 10 kPa/min.
High pressure test:
During the test, the test sample is in a non-working state. Place the pretreated test sample into a test chamber under normal atmospheric conditions, then raise the air pressure in the test chamber to a specified pressure value at a specified average rate, and expose it to this condition for a specified duration.
