Test Method 3
3.1 Equipment
3.1.1 Temperature/humidity chamber. The temperature can be maintained at 75 ℃ ± 2 ℃, relative humidity can be maintained at 93% ± 2%.
3.1.2 cryostat tank. the temperature can be maintained at -50 ℃ ± 2 ℃.
3.1.3 Temperature/humidity automatic recording system. real-time measurement, recording and storage temperature/humidity test chamber temperature and humidity, and can record low
Warm incubator temperature.
NOTE. As a climatic chamber can meet the requirements of 3.1.1 and 3.1.2, you can only use the same climatic chamber.
3.2 Sample Requirements
