The  MIL-STD-810D  specifies the conditions, procedures, methods and evaluation indexes of low temperature test for military equipment, aiming at assessing the impact of low temperature environment on the safety, integrity and performance of equipment.


MIL-STD-810D low-temperature test method test purpose

Low-temperature test mainly simulates the equipment in storage, transport and use in the process of low-temperature environment may be encountered, by simulating the extreme cold conditions, to examine the equipment in the low-temperature changes in physical properties, functional performance changes and environmental adaptability.


MIL-STD-810D low-temperature test method test conditions

MIL-STD-810D standard low-temperature test temperature range is as follows:

Temperature Range:The low temperature test temperature range specified in the MIL-STD-810D standard is typically -55°C to -65°C.

Test Time:In low temperature testing, samples need to be held in a specified low temperature environment for a certain amount of time. For example, samples need to be held at -55°C for 4 hours.

MIL-STD-810D standard specifies the temperature uniformity and temperature fluctuation of the test equipment and other technical indicators to ensure the accuracy and reliability of the test results. Specific requirements are as follows:

Temperature uniformity: the temperature distribution within the test equipment should be uniform, to ensure that the temperature difference between the test points within the specified range.

Temperature fluctuation: during the test, the temperature change should be within the allowable fluctuation range to ensure the stability of the test conditions.


(ESS) High And Low Temperature Test Chamber description

Sanwood's (ESS) High And Low Temperature Test Chamber is a high-performance test equipment widely used in aerospace, aviation, electronics, automotive, battery and other industries.
