The standard for high temperature aging test test Box structure and appearance requirements: >
1. The inner wall should be manufactured with heat resistance and not easy to oxidize and a certain mechanical strength;
2. The thickness of the insulation material is high -temperature resistant to high temperature and has self -extinguishing performance; > 3. The temperature of the external access to the site is not higher than 50 ° C;
4. The heating device must not constitute the direct radiation of the test sample;
5. Observation windows should be provided, and lighting devices should be provided in the studio;
6.
7. The sealing bar of the box door should not be easily aging, hair sticky, deformation, Lost sealing performance, and should be convenient for replacement;
9. Instruments or devices such as temperature adjustment, instructions, records, etc. should be possessed;
10. The appearance of the coating should be smooth and smooth, and the color is uniform. There must be no dew, foaming, starting layer or scratch traces.
The calculation and evaluation of the test results of the high temperature aging test box: > 1. Correct the measured temperature values according to the correction value of the test instrument;
2. Use 15 test data in 30 minutes to find the height and low temperature in each test The average arithmetic value of the difference is the temperature uniformity of the temperature at the nominal temperature; the 15 test values of the central test point are higher than half of the low temperature difference between the low temperature, and the crown is ±. Volatility at temperature.
3. Use 24h test data to calculate the difference between 蕞 height, low temperature and nominal temperature, respectively,
High -temperature aging test box The temperature deviation of the temperature at the nominal temperature. >
