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.


  • Testing that complies with JIS C8712 and UN Manual of Test and Criteria* (20°C±5°C, 11.6 kPa or less for at least 6 hours)
    *UN Manual of Test and Criteria, Part III, Test T.1
    JIS C8712 (Safety requirements for portable sealed secondary cells)
  • Support for use in a clean room when installed in a clean room
  • Magnetic coupling air circulator
  • Safety devices for protecting the specimen temperature and refrigeration circuit
