Within the adjustable range of the high temperature test chamber, select the highest nominal temperature or the temperature required by the user as the test temperature. as follows:
1. After the temperature at the test point in the center of the work space reaches the test temperature for the first time and stabilizes for 2 hours, test the temperature of all test points every 2 minutes, measure 15 times within 30 minutes, and measure again every 30 minutes. Test once every 1h for a total of 24h. The test procedure of the test method specified in the standard of the high temperature test chamber 2. Calculation and evaluation of the test result: the measured temperature value is corrected according to the correction value of the test instrument.
3. Using the 15 test data within 30min, find the arithmetic average of the difference between the highest and the lowest temperature in each test, and find the 15 test values ​​of the central test point for the temperature uniformity at the nominal temperature The middle and highest temperatures are half of the temperature, and are marked with "±", which is the fluctuation of the nominal temperature.
4. Using the 24h test data, calculate the difference between the highest and lowest temperature and the nominal temperature, which is the temperature deviation of the high temperature test chamber at the nominal temperature.
Note: The above are the calculation results of the high-temperature test chamber, which should meet the requirements of Articles 4.1.1 ~ 4.1.3.
