GB/T 32221-2015 Sanwood Technology Large Altitude Test Chamber: Boosting the Development of the Aviation Industry

Sanwood Technology Large Altitude Test Chamber, built strictly in accordance with GB/T 32221-2015, can accurately simulate the space environment under extreme vacuum and -70°C ~ +150°C conditions, providing highly reliable verification for aerospace

In humanity's quest for space exploration, the reliable operation of every satellite and spacecraft begins with countless rigorous extreme tests in ground-based laboratories. Sanwood Technology's Large Altitude Test Chambers are critical equipment for simulating space environments and verifying product reliability. They strictly adhere to the national standard GB/T 32221-2015, providing comprehensive support for aerospace customers from material testing to complete system validation.

GB/T 32221-2015, "Vacuum Technology - Vacuum Thermal Environment Simulation Test Equipment for Spacecraft - General Technical Requirements," is a national standard that regulates the design, manufacture, inspection, and acceptance of thermal vacuum and thermal balance test equipment for spacecraft (satellites, spacecraft, space probes, etc.). Its core purpose is to ensure that such critical equipment can simulate the vacuum, cold darkness, and solar radiation conditions of space on the ground, thereby verifying the performance, reliability, and lifespan of a spacecraft's thermal control system during in-orbit operation. This standard applies to vacuum thermal environment simulation test equipment operating at pressures between 1×10⁻² Pa and 1×10⁻⁴ Pa.
