GB/T 38924.2-2020 "Methods for environmental testing of civil light and small drone systems, Part 2: Low temperature testing" specifies the requirements for low temperature environment testing of civil light and small drone systems (including aircraft and ground stations). The standard covers test conditions, equipment and instrument selection, test process, test interruption and recovery, evaluation of results and preparation of test reports. This part aims to evaluate the adaptability of drone systems in low temperature environments, ensuring their Reliability and Stability in extremely low temperature conditions. The standard applies to any drone system that may encounter low temperature environments, helping to confirm its performance and tolerance in low temperature conditions.
