Temperature gradient: the maximum value of the difference between the average temperatures of any two points in the working space after stabilization ; 3. The temperature fluctuation: after the stabilization, the difference between the maximum and minimum temperatures at any point in the space ; 4. The working room The difference between the wall temperature and the working space temperature: 1) The high temperature level should not exceed 3% of the test chamber temperature. 2) The low temperature level should not exceed 8% of the test chamber temperature . 5 , Temperature deviation: ± 2; 6, the rate of temperature change: measured at the center in the working space to the transition rate between two given temperature to ℃ / min units; Second, furniture testing equipment structure requirements 1.
