The relevant sequence in the test process of the high and low temperature test chamber is as follows: First, start from the environmental conditions (the optimal ambient temperature and humidity are: 5 ℃ ～ + 30 ℃ ≤85% RH), then adjust the test chamber to the highest specified temperature and stabilize it The performance at the highest temperature, then adjust to the lowest stable and stable and then measure the lowest time, then adjust the test chamber to the highest specified temperature, monitor the temperature change rate, and adjust the test chamber to atmospheric conditions and stabilize it, measure the atmospheric conditions Performance.
The picture above is: the temperature test change rate of heating and cooling of the test box
The test report is derived from the data in the test test results. If all test results are within the range specified in the relevant part of GB / T 2423, the performance is approved and means qualified.
The information that the performance test report should contain:
A. Atmospheric conditions in the test area
B. The size and volume of the test chamber and working space
C. Temperature fluctuations, space temperature changes and temperature test gradients specified in the standards at various stages
D. Temperature change rate of heating and cooling
E. Extreme temperature
F. Real data of any deviation
G. Test load and load
H. Details of the data acquisition system
I. Evaluation of measurement uncertainty
J. Report issuing unit, time, tester
