Confirming the temperature grade and deviation of the high and low temperature test chambers is one of the problems in which the type of test equipment purchased by the customer makes the final judgment. This chapter explains the temperature grade and deviation of high and low temperature test chambers by small series: The high temperature temperature deviation of the high and low temperature test chamber is not more than ± 2 ° C, and the high temperature temperature grade is: 30 ° C, 40 ° C, 55 ° C, 70 ° C, 85 ° C, 100 ° C, 125 ° C, 155 ° C, 175 ° C, 200 ° C. The low temperature temperature deviation of the high and low temperature test chamber is not more than ±3 °C, and the low temperature temperature grade is: 5 °C, -5 °C, -10 °C, -25 °C, -40 °C, -55 °C, -65 °C. The temperature uniformity of the high and low temperature test chamber test chamber at high temperature and low temperature should be no more than 2.0 °C. The temperature fluctuation of the high and low temperature test chamber test chamber is not more than ±0.5 °C at high temperature and not more than ±1.0 °C at low temperature. The difference between the temperature of the inner wall of the studio and the temperature of the working space: the difference between the temperature of the inner wall of the test chamber of the high and low temperature test chamber and the temperature of the working space should not be more than 3% of the temperature of the test chamber at high temperature and not more than 8% at low temperature. High and low temperature test chamber heating and cooling rate: Under full load conditions, the rate of uniform temperature rise and temperature drop every 5 minutes is: no more than 1 °C / min, 1 ± 0.2 ° C / min, 3 ± 0.6 ° C / min, 5 ± 1 °C/min. Since the high and low temperature test chamber adopts the blast principle to ensure the uniformity inside the box, the wind speed in the working space should be adjustable. However, the equipment is mainly not used for windproof tests, so only the standard value is used: 3.7m/s.
