Classification of UL 1703 Humidity Test Chamber

According to UL 1703 (36),

Each cycle is to consist of:

a) A transition in the test chamber temperature from 25°C to 85°C (77°F to 185°F);

b) A dwell at 85°C for 20 h minimum;

c) A transition from 85°C to minus 40°C (minus 40°F);

d) A dwell at minus 40°C for 30 minutes minimum; and

e) A transition from minus 40°C to 25°C. When the temperature is 0°C (32°F) or above, the

temperature transitions of the test chamber with respect to time are not to be greater than

120°C/h (216°F/h). When the temperature is less than 0°C, the temperature transitions of the

test chamber with respect to time are not to be greater than 200°C/h (360°F/h). The total time

for the transitions and the minus 40°C dwell together is not to exceed 4 h. If the 25 °C

temperature is the start or end of the 10 cycles, any nominal room temperature in the range

15°C – 30°C (59°F – 86°F) may be used. The total cycle time is not to exceed 24 h. See Figure 36.1.
