Altitude Temperature Chamber

Perform aviation testing (using UN testing criteria) of lithium ion batteries

Lithium ion batteries are defined as hazardous materials under the UN Restriction of Hazardous Substances and must comply with these restrictions for transportation.
They must pass the UN Manual of Test and Criteria, which includes low-pressure (high-altitude), thermal cycle, vibration, and shock criteria.
This chamber can be used to perform low-pressure (high-altitude) testing in accordance with the UN Manual of Test and Criteria for air transport.
