Introduction:

The purpose of the low-temperature laboratory is to determine the adaptability of military and civilian equipment or products during storage and operation under low-temperature conditions. The technical indicators for low-temperature testing (experiments) include: temperature range, duration, heating rate, and cooling rate. To maintain uniform surface temperature of the sample, the distance between the sample and the chamber wall should be at least 5 cm when placing the sample inside the test chamber.

After the experiment, the sample needs to be restored to a stable state indoors or placed in a normal temperature and humidity environment until stability is achieved. Under specific conditions, slightly warm air may be blown onto the sample for thawing before observing changes in its performance indicators.
